In this instructable I show you how I made a simple RFID UID reader which reads the UID of a Mifare RFID card.

The program is quite simple and on a breadboard the reader was quickly made. Then I soldered it all on a piece of perf board and I designed an enclosure for it.

It has a built-in LiPo charger.

Supplies:
I bought the components from Aliexpress:

- Oled screen (SPI)
- MFRC522 RFID module
- TP4056 charger IC
- Arduino pro mini 3.3V 328P
- LiPo battery”
