February 2007 I came to the conclusion that my idea for a simple RFID-reader that must work. Since it was so simple.
Some days before I placed my order I noticed that the swedish computer magazine Dator Magazin ran an article about building a RFID reader that used the exact parts I was considering buying. So well someone had already proved that it was going to work.
Wiring USB TTL-232 - RFID reader module
Components: Basically it's a prallax RFID reader module and a USB TTL-232 adaptor.
