Mainland bank cards are generally UnionPay cards, and only those merchants with UnionPay logo can swipe their cards. At present, there are more than 2,000 ATMs and 4,000 POS shops with UnionPay logo in Hong Kong. The scope of application basically covers major tourist areas in Hong Kong, such as major department stores, brand-name stores, audio-visual appliances, fashion clothes, beauty and makeup, etc. in Central, Causeway Bay, Wan Chai, Tsim Sha Tsui and Mong Kok. For example, Wanning, Broadway and Chow Tai Fook can all use UnionPay cards.

Remember to remind the toll collector to swipe the UnionPay channel when you can swipe the UnionPay store, because most of the local bank cards in Hong Kong are now deposited by MasterCard, visa and UnionPay, so if you don't say anything, the toll collector will help you swipe the visa channel, and you will lose a lot. (Mainland UnionPay cards are exempt from handling fees when swiping the UnionPay channel in Hong Kong, and are converted into RMB by China UnionPay according to the selling price of Hong Kong dollars announced by the country on the transaction day, and the issuing bank deducts RMB from the cardholder's account according to this RMB amount. )

Pay attention to payment security and password protection.

When a cardholder swipes a card at a POS machine in Hong Kong, whether it is a debit card or a credit card, he needs to enter a password (if there is no password set on the card, you can press "OK" directly) to protect the interests of the cardholder. Cardholders also need to sign the purchase order for the record. When using, the cashier will check the shopping list and the signature on the back of the card. Therefore, please keep your personal password, whether debit card or credit card, please sign on the back of the card.
