# NFC tag reader with Arduino

> The idea is build a simple prototype to read NFC tags and validate them against a remote server

Original author: Gonzalo Ayuso (source: https://gonzalo123.github.io/2017/06/12/nfc-tag-reader-with-arduino/)

## Components

- **Arduino UNO** x 1 ([docs](https://www.farnell.com/datasheets/1682209.pdf))
- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))

## Documents and links

- [GitHub](https://github.com/gonzalo123/arduino-nfc-reader) (code)

## Article

The idea is build a simple prototype to read NFC tags and validate them against a remote server (for example a node tcp server). Depending on the tag we’ll trigger one digital output or another. In the example we’ll connect leds to those outputs, but in the real life we can open door or something similar.

We’ll use a MFRC522 module. It’s a cheap Mifare RFID/NFC tag reader and writer.

MFRC522 Connection:

- sda: 10 (*) -> 8

- sck: 13

- Mosi: 11

- Miso: 12

- Rq: –

- Gnd: Gnd

- Rst: 9

- 3.3V: 3.3V
