Anyone ever try to read RFID cards? I have worked a lot with barcodes and I'd like to upgrade to RFID. We have HID access badges here at the office. I'm wondering if I can read the cards to identify users. I'm not sure what is on the cards, but all I want to read is any unique value to ID the user and preferably use some kind of keyboard emulation as a barcode reader would do. I saw a cheap reader that may or may not work - omnikey 5321. I don't know enough about the card technologies to know if it's even compatible with the cards we have and what exactly it sends to the application. I did find a USB reader (RFID RW) that mentions keyboard emulation but the company is in Portugal and there is no price listed. Anyone ever try RFID integration? Could really use some advice.
