The difference between RFID card and NFC card
NFC is developed on the basis of RFID, and NFC is not much different from RFID in essence, both are based on the signal transmission between two objects with similar geographical location.
However, there is still a difference between NFC and RFID. NFC technology adds a point-to-point communication function, which can quickly establish P2P (point-to-point) wireless communication between Bluetooth devices. NFC devices find each other and establish communication connections. The two devices in P2P communication are peer-to-peer, while the two devices in RFID communication are in a master-slave relationship.
There are some other technical details:
Compared with RFID technology, NFC has some characteristics such as short distance, high bandwidth, and low energy consumption. details:
1. NFC is only limited to the 13.56MHz frequency band! The frequency bands of RFID are low frequency (125KHz to 135KHz), high frequency (13.56MHz) and ultra high frequency (860MHz to 960MHz).
2. Working effective distance: NFC (less than 10cm, so it has high security), RFID distance from a few meters to tens of meters!
3. Because it also works at 13.56MHz, NFC is compatible with the existing contactless smart card technology, so many manufacturers and related groups support NFC, while there are many RFID standards, and the unification is more complicated (it is estimated that it is impossible to unify), only Under the special needs of special industries, the corresponding technical standards can be adopted!
4. Application: RFID is more used in production, logistics, tracking, asset management, while NFC plays a huge role in access control, public transportation, mobile payment and other fields.

Differences between Mifare series cards
Mifare series cards are divided into
Mifare UltraLight, also known as MF0;
Mifare S50 and S70, also known as MF1;
Mifare Pro, also known as MF2;
Mifare Desfire, also known as MF3.
Mifare 1 has a password, Mifare UltraLight has no password.
M1/ML/UtralLight/Mifare Pro comply with the 14443A protocol, AT88RF020 complies with the 14443B protocol, and the Fudan card depends on which one it is.
