Things used in this project

Hardware components:
11113 01
SparkFun Arduino Pro Mini 328 - 5V/16MHz
×2
RFID reader (generic)
Any (small) reader will suffice, as long as the antenna is made of wire, not embedded in a board.
×1
SparkFun RFID Tag
Remember they have to be compatible, i.e. same frequency, with the reader

10217 02a
SparkFun SparkFun LiPo Charger Basic - Micro-USB
Or similar. The USB input socket is not neccessary, yet useful if the other way of charging fails.
×1
10968 01
SparkFun Step-Up Voltage Regulator - 5V
Or similar - I used one with a built-in USB socket and cut it out.
