1. First go to mobile phone settings-other networks and connections/more settings -NFC- turn on NFC switch and NFC card reading switch, and set the payment method as vivo wallet.

2. Then enter the access card page of vivo wallet and select the type of card to open.

3. Put the unencrypted physical campus card near the NFC antenna of the mobile phone to read the card.

4. According to the page prompts, complete the authentication and write the card, and you can add the campus card.

The premise is that the mobile phone has NFC, and it is necessary to ensure that the NFC function is turned on. The payment method is vivo wallet.

Near Field Communication (NFC) is a new technology. Devices using NFC technology (such as mobile phones) can exchange data when they are close to each other.

It is developed from the integration of contactless radio frequency identification (RFID) and internet technology. By integrating the functions of sensor card reader, sensor card and point-to-point communication on a single chip, mobile terminals are used to realize applications such as mobile payment, electronic ticketing, access control, mobile identity recognition and anti-counterfeiting.

NFC is called near field communication technology in Chinese. NFC is developed on the basis of non-contact radio frequency identification (RFID) technology combined with wireless interconnection technology, which provides a very safe and fast communication mode for various electronic products that are becoming more and more popular in our daily life.

The "near field" in the Chinese name of NFC refers to the radio waves near the electromagnetic field. Because radio wave is actually electromagnetic wave, it follows Maxwell's equation, and the electric field and magnetic field will always alternate energy conversion in the process of propagating from the transmitting antenna to the receiving antenna, and will strengthen each other in the process of conversion.
