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.....
