What are NFC and QR Code Payment? All you need to know about mobile payment

With the increasing popularity of smartphones, many people start to go out with only a mobile phone, because the phone can not only make phone calls and play games, but also can be used for payment. The most common tools are Apple Pay, Google Pay, Alipay, WeChat Pay, etc. Mobile payment can be divided into two types: NFC payment and QR Code payment.

NFC payment

NFC (Near Field Communication) is used for contactless identification and interconnection of two electronic devices. It allows two electronic devices to send and receive data within a few centimetres of each other. Nowadays, most smartphones have built-in NFC functions, which can be used to complete contactless mobile payment. Apps supporting this function include Apple Pay, Google Pay, Samsung Pay, Huawei Pay, etc. 

Customers only need to add their credit or debit cards to the wallet app (e.g. Apple Wallet, Google Pay, Samsung Pay, Huawei Wallet, etc.) on their smartphones in advance. After that, even if the phone is not connected to the network, they can still use it to make NFC payments at stores with contactless payment logo.

In fact, NFC payment is more secure and less prone to card theft than normal credit card payment, because NFC payment requires double verification with fingerprint or face recognition to confirm the cardholder's identity before the payment can be made.

QR Code Payment

QR Code (or “two-dimensional code”) payment is another popular mobile payment in recent years. Customers can complete the transaction by showing the payment QR code to the merchant through their mobile wallets, such as AlipayHK, WeChat Pay HK, UnionPay Cloud QuickPass, BoC Pay, etc. Unlike NFC payment, QR code payment requires an Internet connection to obtain the QR code after entering the payment password. 

Currently, AlipayHK, WeChat Pay HK and other wallets can be linked with not only credit cards, but also bank accounts, so that even people without credit cards can pay with their phones. Moreover, mobile wallets will launch payment offers from time to time through collecting stamps to redeem cash coupons and other cash rebate offers, thus attracting a lot of users. 

The popularity of mobile payment not only eliminates the need to carry a physical wallet, but also the hassle of dealing with changes among other concerns. The biggest appeal might be the rebate offer of electronic payment tools, which is the reason many consumers began to use the technology in the first place.
