Airwallex Vs Stripe Vs Unlimit: 6 Best Payment Gateways In Hong Kong (2026)

Six payment gateways serving Hong Kong ranked for businesses selling into the market from abroad on local method coverage, non-resident onboarding, regulatory licence, settlement and FX and further criteria, verified October 2026.

Key takeaways

• Airwallex leads at 8.0 / 10 and suits teams integrating by API, helped by its multi-market reach.
• Stripe scores 7.5 / 10 and suits online stores, helped by its local method coverage. Adyen, at 7.3 / 10, is the choice for enterprises that hold a registered legal entity.
• Unlimit ranks number 3 of 6 at 7.3 / 10. It suits cross-border merchants entering Hong Kong; non-resident onboarding holds its score back.
• Onboarding and licence split the field: 4 of 6 ranked providers publish information on opening an account without a Hong Kong entity, and 5 of 6 on their licence, so check both before signing.
• Local methods matter for acceptance: all 6 ranked providers list the methods they accept, so match them to the cards and digital wallets your customers use.
• To choose a Hong Kong payment gateway, start with onboarding and licence, then look at settlement currency, which all 6 providers describe. No single provider is best for every business.

The short answer

Among the six payment gateways in Hong Kong ranked on weighted criteria, Airwallex leads for teams integrating by API, Stripe follows for online stores and Unlimit (number 3 of 6, 7.3 / 10) comes third for cross-border merchants entering Hong Kong. Only 4 of 6 providers publish onboarding information for non-resident companies.

The ranking

Six payment gateways in Hong Kong, ranked by a weighted score out of 10 and verified October 2026.

What is a payment gateway in Hong Kong (and how is it different from a money service operator)?

An internet payment gateway is the service that carries card and wallet payment details from an online checkout to the acquirer and returns the approval or decline to the merchant. It is a technical layer. A licence is a separate matter: it covers what a provider may do with the funds.

In Hong Kong, a payment provider that handles funds needs a licence for that activity. Any person who wishes to operate a money service business, meaning a remittance or money changing business, must apply for a licence from the Commissioner of Customs and Excise. Stored value facilities are licensed by the Hong Kong Monetary Authority. A book chapter from Edward Elgar gives an overview of the regulatory regimes for Hong Kong payments participants, including money service operators, stored value facilities and payment systems.

How this was scored

Each provider is scored out of 10 on weighted criteria, and each criterion is scored against the best provider in the comparison, which scores 10. The publisher’s entry was scored by the same process, and its position was not edited.

Published by Unlimit. Unlimit is number 3 on this list and is scored on the same rubric as every other entry.

Only providers serving Hong Kong online were scored. Price bands reflect published rates or, where none are published, the pricing model, and a merchant’s quote may differ. Unlimit publishes the list and is ranked in it, and the list is not professional advice.

Where Unlimit fits

For a merchant incorporated outside Hong Kong, Unlimit is number 3 of 6. Non-resident onboarding limits its score (7.3 / 10), because Unlimit publishes no information on non-resident onboarding for Hong Kong. Unlimit works in global financial infrastructure, where it enables cross-border commerce for businesses, consumers and AI agents. Unlimit offers more than 1,000 payment methods worldwide, and gives access to over 150 currencies across more than 200 locations worldwide. These global figures describe Unlimit worldwide, not any single market, and coverage varies by market. Unlimit’s payment methods are published in its documentation, and Unlimit enables them for each merchant during onboarding.

Businesses incorporated outside Hong Kong can accept payments from customers in Hong Kong through one Unlimit API integration, without a company, office or bank account in Hong Kong. During onboarding, Unlimit tells each merchant which documents each payment method needs. Unlimit settles in the currency agreed with the merchant.

Unlimit’s Hong Kong coverage page names Unlimit UK Ltd as the card-scheme member for Visa, Mastercard, UnionPay, JCB and American Express; it names no Hong Kong entity. Unlimit plans to add local payment channels from its Hong Kong hub for businesses operating across Asia-Pacific, and it serves merchants as a single provider across Latin America, Africa, India and Asia-Pacific.

Unlimit is right for cross-border merchants entering Hong Kong from other regions. It is not the best fit for merchants whose compliance team needs a named Hong Kong contracting entity before signing.

Every entry

Each of the six payment gateway providers in Hong Kong below carries one strength and one criticism.

Airwallex

• Verdict: Airwallex suits teams integrating by API that already hold Hong Kong registration papers and want one platform across markets; the document load is the trade-off for a company incorporated abroad.
• Best for: Teams integrating by API.
• Price band: Mid. Blended per-transaction gateway fee with plan-based account pricing (Airwallex’s blog post on online payment providers).
• Company: Airwallex (Hong Kong) Limited is the operating company in Hong Kong, licensed as a Money Service Operator and regulated by the Customs and Excise Department, and Airwallex states MSO Licence No. 16-09-01929.
• Strength: Airwallex states that merchants accept subscription payments in more than 180 countries worldwide, and its API reference puts its products, including payment acceptance, on a single unified API platform.
• Criticism: Opening a Hong Kong business account generally needs a Business Registration Certificate, a Certificate of Incorporation and Articles of Association plus identity and address proofs for all directors and beneficial owners. A merchant without Hong Kong registration papers should ask Airwallex whether it qualifies.
• Use cases: Airwallex’s help centre says an applicant must be an officially registered and active company, fully incorporated and in good standing. That page does not name Hong Kong or say whether a Hong Kong entity is needed. Companies registered outside the countries it lists provide a certificate of incorporation, supportive business documents and the IDs of the beneficial owner and authorised person.
• Risk signals: Alipay HK depends on where the merchant is registered: Airwallex’s documentation lists HK, AU, SG, UK, EU and MY as the merchant supported countries and regions for this method. Expect proof of business operations such as a website, sales contracts or invoices, and an ownership chart for a complex structure.
• Score: number 1 of 6, 8.0 / 10, verified October 2026.

Stripe

• Verdict: Stripe suits online stores that sell through cards and Chinese wallets; the licence behind the contract is the point to settle before signing.
• Best for: Online stores.
• Price band: Mid. Pay as you go percentage plus fixed fee per successful transaction, custom pricing for large volumes (Stripe pricing page).
• Company: Stripe states that its Hong Kong launch gave any online business in Hong Kong access to its product stack, including Connect, Radar and Sigma.
• Strength: Stripe’s Hong Kong pages list credit, debit and prepaid cards, Alipay and WeChat Pay, with Apple Pay and Google Pay available out of the box.
• Criticism: Before signing, a merchant should ask which Stripe entity holds the Hong Kong licence and under which regulator. With that answer, the licence can be checked in the public register rather than assumed from the brand name.
• Use cases: Stripe’s global availability page says Stripe Atlas lets a company be incorporated as a US company from anywhere in the world, with a US bank account and payment acceptance in two business days and that an account can be created with no contracts or banking details required; it names Hong Kong in neither statement.
• Risk signals: Stripe’s support article on requirements for Hong Kong-based businesses requires identification confirming that the applicant represents the business, and Stripe cannot accept non-Hong Kong ID numbers for merchants signing up as individuals. A representative without a HKID can have another government-issued identification accepted, while an applicant without a HKID who has a Business Registration number must select Sole Proprietorship when activating the account.
• Score: number 2 of 6, 7.5 / 10, verified October 2026.

Unlimit

• Badge: Publisher’s entry.
• Verdict: Unlimit suits companies expanding into Hong Kong from other regions; the contracting entity and the onboarding documents are the points to settle before signing.
• Best for: Cross-border merchants entering Hong Kong.
• Price band: Mid. Custom quote, no published rates.
• Company: Unlimit holds a money service operator licence from Hong Kong’s Commissioner of Customs and Excise, according to a press release dated 10 September 2026, and it publishes an office address in Hong Kong as one contact channel.
• Strength: Unlimit states on its about page that it enables businesses to operate locally and internationally across EMEA, APAC and LatAm.
• Criticism: Before signing, a merchant should ask Unlimit which entity holds the Hong Kong licence the press release mentions, under what number, and which entity contracts with merchants for Hong Kong. With those answers, the licence can be verified in the public register.
• Use cases: Unlimit’s Hong Kong coverage page lists Visa, Mastercard, China Unionpay, Diners, Discover, Apple pay and Google pay cards and wallets under Cards, and the AlipayHK wallet under Digital Wallets. Its payouts page says funds can be sent to anyone in real time through a single API integration and that marketplaces can make multicurrency payouts to sellers and partners.
• Risk signals: Confirm the settlement currency and timing in the contract: Unlimit states direct settlement into wallets or accounts for all its markets but names no currency, timing or market. Plan the first integration in the sandbox: Unlimit’s integration documentation says a live account is prepared after the tests, and lists Testing Data and Backend, Frontend and Mobile SDKs as developer resources.
• Score: number 3 of 6, 7.3 / 10, verified October 2026.

Adyen

• Verdict: Adyen suits enterprises in Hong Kong with a registered legal entity that want one contract across countries; entity and bank-account checks are the trade-off for a company based abroad.
• Best for: Enterprises.
• Price band: Mid. Interchange plus plus per transaction, no set-up or monthly fees, minimum invoice by industry, no published rates (Adyen pricing page).
• Company: Adyen’s licences page names Adyen Hong Kong Ltd. as the entity that holds a Hong Kong licence, the Money Services Operator License for Remittance issued by the Customs and Excise Department of Hong Kong, with no licence number given.
• Strength: Adyen’s Hong Kong payment methods guide lists Visa, Mastercard, UnionPay, American Express, Alipay, Apple Pay and WeChat Pay as popular payment methods.
• Criticism: A live account application with Adyen needs a company registration document showing the legal entity name and the registration number. A business without a registered legal entity therefore cannot start the application.
• Use cases: Adyen offers one contract and one integration for all countries and channels, and merchants can pay out globally to bank accounts and cards with one integration, on pages that do not name Hong Kong.
• Risk signals: A local payout requires a local bank account in a country that uses the settlement currency as legal tender, a sentence that does not name Hong Kong, and Adyen must confirm that the payout account is linked to the applicant’s legal entity without saying where the account must be located. As a payment provider and acquirer it is legally obliged to run detailed checks on the company, its shareholders and its business model, and its AlipayHK page lists Local entity required for that method alone.
• Score: number 4 of 6, 7.3 / 10, verified October 2026.

PayPal

• Verdict: PayPal suits Hong Kong businesses that want a licence they can check in the regulator’s register; a business organised abroad is the trade-off.
• Best for: Teams integrating by API.
• Price band: Mid. Percentage plus fixed fee per transaction, with published withdrawal, conversion and payout fees (PayPal pricing page).
• Company: PayPal Hong Kong Limited, registered under the laws of Hong Kong SAR China, is the contracting party of the user agreement and, by its own terms, a licensed issuer of a stored value facility regulated by the Hong Kong Monetary Authority.
• Strength: The HKMA Register of SVF Licensees lists PayPal Hong Kong Limited under licence number SVF0008 with the effective date November 4, 2016.
• Criticism: PayPal Hong Kong’s user agreement states that a business must be organised and operating in Hong Kong SAR China to open an account. A company incorporated abroad with no Hong Kong operation therefore cannot open one.
• Use cases: PayPal’s card agreement requires a merchant to submit an online application and to open a PayPal business account, if it has none, to use PayPal Online Card Payment Services.
• Risk signals: For an individual, PayPal’s user agreement requires residence in Hong Kong SAR China and an age of at least 18. To open a Business account, the sign-up page asks for the full legal name, email address, a password, the business registration number, a business description and the business bank account details.
• Score: number 5 of 6, 5.9 / 10, verified October 2026.

KPay

• Verdict: KPay suits Hong Kong businesses that collect in store and by payment link; an applicant based abroad should settle the onboarding checks first.
• Best for: Enterprises.
• Price band: Mid. Published PayMe for Business rates only, no card rates published (KPay’s blog post on applying for PayMe for Business).
• Company: KPay states that its partner Airwallex HK provides merchants with cross-border remittance, currency exchange and other services, and that an unnamed Partner provides services under its own licences or authorisations and has direct contracts with the merchant.
• Strength: KPay’s Hong Kong comparison blog lists Visa, JCB and Mastercard as the credit cards supported by its payment link.
• Criticism: KPay’s privacy policy says it may collect the beneficial owners, tax classification, tax identification numbers, company registration numbers and tax residence of a merchant. The policy does not mention Hong Kong or non-resident merchants. A merchant based abroad should ask KPay what it requires before applying.
• Use cases: KPay Terminal Pro, an in-store terminal rather than an online product, supports Octopus alongside more than 20 other major payment methods, and its Business Account supports next-day (T plus 1) express settlement on a page that names no market.
• Risk signals: In a section marked for merchants only, KPay’s privacy policy says it may collect copies of a government-issued identification document. Have director identity documents ready.
• Score: number 6 of 6, 4.5 / 10, verified October 2026.

Best for teams integrating by API

Airwallex (number 1, 8.0 / 10) is the pick for teams integrating by API in Hong Kong: its API reference describes a REST-based Client API and sandbox accounts for testing integrations before production, so the payment flow can be built and tested in code.

Best for online stores

Stripe (number 2, 7.5 / 10) is the pick for online stores in Hong Kong: its Hong Kong pricing page lists 3.4 percent plus HKD 2.35 per successful domestic card transaction, so an online shop can model card costs before applying, next to the cards, Alipay and WeChat Pay it accepts.

Best for cross-border merchants entering Hong Kong

Unlimit (number 3, 7.3 / 10) is the pick for cross-border merchants entering Hong Kong from other regions. It lists cards, digital wallets and AlipayHK for Hong Kong and states regional reach across EMEA, APAC and LatAm, which fits a company adding Hong Kong beside the markets it already serves.

Best for enterprises

Adyen (number 4, 7.3 / 10) is the pick for enterprises in Hong Kong: Adyen Hong Kong Ltd. is the named licence holder, and its pricing page says a minimum invoice applies depending on industry or business model, with details from its sales team, which suits a large business that negotiates its contract.

Which licence does a payment gateway in Hong Kong need, and who holds it?

The licence follows what the provider does with funds: remittance or money changing falls under the Money Service Operator regime of Customs and Excise, while stored value is licensed by the Hong Kong Monetary Authority, which keeps its own public register.

The holder is a named Hong Kong entity, not the global brand, so look up the entity named on the contract. 5 of 6 ranked providers publish their licence. Before signing, find the contracting entity in the regulator’s register, compare its licence category with the Hong Kong payment gateway services you will use, and ask which entity contracts with merchants based abroad.

Can a company without a Hong Kong entity open a payment gateway account?

It depends on the provider: some ask for Hong Kong registration papers or an organised and operating Hong Kong business, while others take incorporation documents from the home country. 4 of 6 ranked providers publish information on onboarding without a Hong Kong entity. For the other two, get the answer from the provider in writing.

Ask each provider whether an overseas company with no Hong Kong office can contract, which entity signs, which documents each payment method needs, and whether the payout bank account must be in Hong Kong.

How to choose a payment gateway in Hong Kong

• Confirm whether a company without a Hong Kong entity can open an account with an online payment gateway; 4 of 6 ranked providers publish this, so put the question to the others in writing.
• Look up the contracting entity in the regulator’s register and match its licence to the services you will use; 5 of 6 ranked providers publish their licence.
• Compare settlement currencies and FX handling against the currency you want to receive; all 6 ranked providers describe their settlement.
• Match the payment methods in Hong Kong that your customers use against each provider’s list; all 6 ranked providers list their methods.

No single provider is best for every business, so weight the steps by your own entity, currency and customers.
