Clarify transaction fees, monthly charges and settlement

As with card terminals, a payment app's main cost is the Transaction fee (MDR) , calculated as a percentage of each sale. Before applying, ask:

  • Rates by payment method: Are Visa, Mastercard, American Express and WeChat Pay charged differently?
  • In-person vs remote transactions: Do card-not-present and in-person transactions have the same rate?
  • Instalment fees: Does the merchant or customer pay? How much for each instalment term?
  • Monthly and account-opening fees: Are there fixed charges or minimum transaction requirements?
  • Settlement: When do funds arrive? Are instant transfers for higher-risk merchants charged separately?
  • Refunds and chargebacks: How are refund and chargeback processing fees calculated?

For how transaction fees, monthly charges and rental affect costs, see the homepage's our complete card terminal charges guide .

*Actual rates and terms depend on platform approval and the contract.

Remote payment security: 3-D Secure, chargebacks and PCI DSS

Remote and online payments are card-not-present transactions. Without seeing the physical card, stolen-card risks are higher than for taps or chip payments. Reports in September 2026 described over 100 police reports involving stolen card details used for phone pre-orders, totalling about HK$4.6 million. Such incidents highlight the importance of remote payment security.

3-D Secure: additional authentication for online payments

3-D Secure (3DS) exchanges information between the merchant, issuing bank and cardholder to verify an online purchase. Network brands include Visa Secure, Mastercard Identity Check and American Express SafeKey. Cardholders may confirm through their bank app or enter a one-time password. Banks describe 3DS as additional protection, but merchants determine its use, so confirm that your payment page supports it.

How does a chargeback work?

  1. The cardholder disputes a transaction with the issuing bank.
  2. The issuer assesses whether the claim may be valid.
  3. The issuer informs the card network, and funds may be temporarily returned to the cardholder.
  4. The merchant responds with evidence such as orders, receipts, communications and delivery records.

PCI DSS card-data security standard

PCI DSS was established through the five founding members of the PCI Security Standards Council: Visa, Mastercard, American Express, Discover and JCB. When choosing a platform, confirm its PCI DSS certification to protect customers' card data.

Remote collection security checklist

  • Do not collect full card numbers or security codes over WhatsApp, email or paper
  • Use only payment links or pages supplied by the payment platform
  • Verify identity and contact details for new customers making large orders
  • Watch for repeated transactions on one card in a short time and unusual delivery addresses
  • Keep orders, conversations, receipts and delivery proof for chargeback responses
  • State refund and cancellation policies clearly to reduce disputes
