RC522 13.56Mhz RFID Reader + Card + Keychain

13.56Mhz RFID Reader Module + Card + Keychain

Mini NFC Magnetic Card Tag Reader Personnel Tracking Door Entry Control Counter Portable Handheld Device Rfid

     This set consists of a black RC522 Mini RFID reader / writer module with the NXP MFRC522 chip, 1 white 13.56MHz card and 1 blue keychain tag. The module reads and writes ISO14443A Mifare S50 (1K) and S70 (4K) cards and Ultralight tags contactlessly at 13.56MHz. It is powered from 3.3V, draws 13mA - 26mA while operating and connects to the controller board over the SPI interface.

     It is clearly smaller than the standard blue RC522 board (about 60mm x 40mm): the black PCB measures about 37mm x 25mm and fits behind a device cover or into small enclosures. The antenna coil is printed on the board; the card or keychain is read when brought close to the surface of the module. The 8-pin order is printed on the board (3V3, RST, GND, IRQ, MISO, MOSI, SCK, SDA); the package contains 1 straight and 1 right-angle 8-pin male header, one of which is soldered depending on the mounting.

     By reading the unique UID number of the card and keychain, door access, personnel tracking (attendance), turnstile, smart lock and membership systems can be built; with its write function, balance, counter or user data can also be kept on the card itself.

Key features:

     Small black PCB: At about 37mm x 25mm it takes roughly half the space of the standard RC522 board; suitable for small enclosures and behind-panel mounting.

     Reads and writes: The MFRC522 chip reads the UID of Mifare S50 / S70 cards and writes data to their key-protected blocks.

     Card and keychain included: 1 white 13.56MHz card and 1 blue keychain tag come in the package; the set is ready for the first test.

     SPI connection, 3.3V supply: Single-row 8-pin connection, connects to the controller board over SPI; low consumption with 13mA - 26mA operating current.

     Two header types: Two separate 8-pin headers, straight and right-angle, are supplied; the module can be mounted upright or flat.

Usage information:

• Connect the 3V3 pin to the 3.3V supply and GND to ground; connect SCK, MOSI, MISO to the SPI bus of the controller board, and SDA (SS) and RST to two separate digital pins. The IRQ pin can be left unconnected if interrupts are not used.
• Hold the card or keychain parallel to the surface of the module and bring it close; the best reading is when the card almost touches the module. Do not place the module on a metal surface or inside a metal box, the reading distance gets shorter.
• Solder the right-angle header for upright mounting, the straight header for flat mounting on a board or perfboard.

Applications:

•  Door access control and card entry systems
•  Personnel tracking and attendance (time tracking) devices
•  Turnstile and parking barrier access
•  Smart lock, locker and drawer lock
•  Hotel room card reader trials
•  Gym and club membership card reading
•  Card-based counter, balance and point applications
•  Inventory, asset and stock tag reading
•  School and library card systems
•  Card-activated games and interactive exhibit setups

Things to consider:

•  The module's supply and logic level is 3.3V. Do not apply 5V to the 3V3 pin; the module can be permanently damaged. With 5V logic controller boards a level shifter on the signal lines is recommended.
•  This module reads 13.56MHz cards; it does not read 125kHz (EM4100 etc.) cards. It is not a phone NFC pairing device or a bank card payment terminal.
•  The UID in block 0 of the card is written at the factory and cannot be changed. When changing sector keys and access bits, record the new key; a wrongly written sector trailer (key) block can lock the sector permanently.
•  Because the antenna of the mini module is small, its reading distance is shorter than the standard RC522 board; choose a reader with a larger antenna where longer range is needed.
