What's involved in building your own RFID reader? As you guys would know industrial RFID readers aren't cheap, how do you energise the antenna, then read back the output?

before beginning, you have to know that there are mainly two type of RFID Reader:
- 125 khz : antenna of 100 turn coil
- 13.6 Mhz : antenna of 3-5 turn coil, more sofisticated can include communication protocol and security issues
if it just to open a door or something like that you can use the 125 khz

This is a bit old, but in case someone else is reading in 2012. Actually there are then three "types".. Another common one is 134.2 kHz
Quoted from above answers: ....before beginning, you have to know that there are mainly two type of RFID Reader:
125 khz : antenna of 100 turn coil 13.6 Mhz : antenna of 3-5 turn coil, more sofisticated can include communication protocol and security issues.....
