Things used in this project

Hardware components:
11113 01
SparkFun Arduino Pro Mini 328 - 5V/16MHz
RFID reader (generic)
Any (small) reader will suffice, as long as the antenna is made of wire, not embedded in a board.
SparkFun RFID Tag
Remember they have to be compatible, i.e. same frequency, with the reader
Adafruit industries ada258 image 75px
Li-Ion Battery 1000mAh
Or similar
10217 02a
SparkFun LiPo Charger Basic - Micro-USB
Or similar. The USB input socket is not neccessary, yet useful if the other way of charging fails.
10968 01
SparkFun Step-Up Voltage Regulator - 5V
Or similar - I used one with a built-in USB socket and cut it out.
NRF24L01 board
Reed switch

Linear Regulator (7805)
09590 01
LED (generic)
I used yellow and green for status and "low battery" notifications at the receiver.
12V Power Supply
depending on your electronic lock or other actuator you use, more than 600mA might be neccessary.
Electronic lock
this is just an example of an output for your setup - this might be a regular push/pull solenoid, a simple electromagnet or anything else you want.
DC Barrel Jack
Anything that fits your power supply's output.
09716 01
SparkFun FTDI Basic Breakout - 5V
Or any other USB to UART converter.
