All of these elements are present in the Xiaomi Redmi Note 5. If the RFID tag is inserted into a specific magnetic field, the RFID will emit a signal of a certain frequency – the reader will be able to obtain pieces of information previously written on the RFID tag. If necessary, the RFID reader will also be able to rewrite any information on the RFID tag.

NFC is a bit the same, except that RFID readers and tags are included in NFC technology: An NFC device can be read and modified by another NFC device. The two devices can exchange information. Note that each of the two devices can write information to the other device.

To prevent malware, this last possibility of reciprocal writing requires specific NFC IT security measures. So, your Xiaomi Redmi Note 5 can adopt three modes in NFC:

1. Passive mode: Your Xiaomi Redmi Note 5 becomes an RFID tag containing information that can be read. The reader can obtain this information and modify it if necessary.
