The function of nfc

1, used for quick payment.

With the popularity of mobile payment, NFC technology enables us to use mobile phones or other NFC-enabled devices to make fast and convenient payments. Simply put the device near the NFC-enabled POS terminal to complete the payment. This convenient payment method not only reduces the burden of carrying a lot of cash or credit cards, but also improves the security of payment.

2, for the connection of smart devices

Through NFC technology, we can bring two NFC-enabled devices together to realize wireless connection. For example, we can connect mobile phones and speakers to play music through NFC. In addition, we can also transfer personal information such as files and contacts between NFC-enabled devices. This wireless connection is not only convenient, but also time-saving and labor-saving.

3, used for labeling and ticket sales

We often see NFC tags in supermarkets and buses. By putting the mobile phone near these labels, we can get detailed information of goods, compare prices or get coupons. In addition, NFC technology is widely used as an electronic ticketing system in cinemas, concerts and other activities. As long as the mobile phone is placed near the entrance reader, the authentication and ticket confirmation can be completed.
