Which payment methods should a Hong Kong restaurant accept?

First: do you actually need more of them

"Accept whatever the guest wants to use" sounds obviously right, but every method carries a hidden cost: the till staff must remember which button, someone settles the terminal nightly, someone reconciles a statement monthly, and every discrepancy has to be traced. Five payment methods means five sets of books to tie out.

A more useful approach is to look at your own guests. A neighbourhood cha chaan teng at lunch may be well covered by Octopus and cash. A shop serving tourists cannot skip AlipayHK and WeChat Pay. A delivery-heavy or high-ticket operation needs cards and FPS. Decide from your guest mix, rather than adding a method every time someone asks.

Octopus: fast, but check the hardware and settlement terms

Octopus coverage in Hong Kong needs no explanation, and fast-food and cha chaan teng operators almost always take it. The question is not whether to accept it, but three details: whether the reader is rented or bought, how long settlement takes, and how refunds work.

Octopus refunds do not work like card refunds and are not a single button on the terminal. Ask before you sign: if a guest is charged wrongly, what happens at the counter right then? Discovering this on the day of your first refund is too late.

AlipayHK and WeChat Pay HK: local wallets are not mainland wallets

This one catches a lot of restaurants out. AlipayHK and mainland Alipay are two different wallets, and the same is true of WeChat Pay HK versus mainland WeChat Pay. Enabling the local version does not mean a mainland visitor’s phone will work.

If your shop is in a tourist area, confirm specifically with your provider: are mainland wallets accepted, and if so is settlement in HKD or CNY, and how are the exchange rate and fee applied? This changes what you actually receive.

• Are the local wallets (AlipayHK, WeChat Pay HK) enabled?
• Are mainland wallets (Alipay, WeChat Pay) accepted?
• Is settlement in HKD, or does it involve conversion?
• Merchant-scans-guest or guest-scans-merchant? Fees can differ

FPS: lowest fees, but think about reconciliation

FPS is attractive because the fee is minimal or nil, which is why small shops like it. The cost lands elsewhere: FPS money arrives in your bank account with no automatic link back to the POS ticket, so month-end reconciliation becomes manual, line by line.

The other practical problem is fake screenshots. A guest shows a "transfer successful" screen and the till has little chance of verifying it in the moment, especially during an evening rush. If you accept FPS, require staff to check the actual credit notification in the bank app rather than the guest’s phone.

Cards and EPS: the right question is not "what percent"

Most operators ask acquirers a single question: what is the percentage. That is not enough. Two providers quoting the same 1.x% can cost very differently once you include the monthly minimum, any fixed per-transaction fee, whether settlement is T+1 or T+3, whether refunds carry a charge, how chargebacks are handled, and whether the terminal is rented.

Ask each provider to price your last month’s actual volume, the number of transactions and the average ticket, and give you one total figure. That number is the one you can genuinely compare between providers.

• Is there a monthly minimum fee or minimum volume?
• Is there a fixed per-transaction fee on top of the percentage?
• Is settlement T+1 or T+3? How are weekends treated?
• Do refunds carry a fee? Is the original fee returned?
• Is the terminal rented or bought, and how fast is a replacement?

The real cost is reconciliation, not the processing fee

If a shop takes five payment methods and the POS does not record them separately, closing the day becomes a manual split: how much cash, how much Octopus, how much AlipayHK, how much FPS. A few dollars out and someone re-checks from the start. That time usually costs more than the processing fees.

So when choosing a POS, ask: can one bill be settled with two payment methods, for example Octopus plus cash? Does the daily report break totals down by method? Do delivery-platform orders settle into their own bucket instead of polluting the cash count? Getting those three right saves hours every month.
