What is a Debit Card?

Many people are unfamiliar with the nature and usage of Debit Cards, often confusing them with commonly seen ATM or credit cards in Hong Kong. However, Debit Card is an unique payment method that differs from the concept of "spending future money" with credit cards. Before using a Debit Card, you need to have sufficient funds in your account to complete the transaction.

Debit Cards are also different from ATM cards, as the primary function of ATM cards is not for consumption. They can only be used for UnionPay or EPS payments, with limited capabilities. Debit Cards, on the other hand, support the payment methods of most credit cards. Take Airwallex Borderless Card as an example, it can be used for all Visa Payment Gateway transactions, including contactless payments like Apple Pay and Google Pay, making it very practical.
