Behind the more convenient topic of Apple Pay and Alipay, there are years of debate about the pros and cons of NFC and QR code. More specifically, it is the debate between the near field communication and the graphic code (including QR code, barcode, etc.).
The two-dimensional code encodes "0" and "1" with a point of a specific arrangement and carries information. Information can be output to the network through an image input device or an optical scanning device. Although the reading is slow, one-way, and the amount of information that can be carried is small, the cost is low and the copyability is strong, and it is often used as a one-way read voucher and an identification mark.
NFC evolved from high-frequency wireless communication technology to transmit data through near-field RF signals. Although the cost is high, it can transmit data in two-way communication, fast reading, high security, and includes various methods such as card and device, device and device (reader mode is reading, card emulation mode is read, point-to-point mode) Is interactive), a wide range of applications, such as access control, payment.
Many analysts believe that NFC has a better outlook, especially in line with mobile payments – non-contact, fast, and secure. In addition to mobile payments, bus cards, data transmission, new train tickets, boarding passes, access control, etc. can be achieved through NFC technology. It seems that NFC is the future of smart living.
In fact, whether it is the application of NFC in payment, or the application of QR code in payment and voucher, it is just the tip of the iceberg. Their larger application is to provide solutions for the connection of the Internet of Things.
