Read/Write to RFID

Question

I have a RFID card reader device from unknown company. I'd like to read/write to it using any programming language.

My question: is there a general way to read/write cards (using C# as example)? Do I need a specific driver/API for every RFID reader?

Answer 1

No, but without drivers you can try to read raw data from USB device and find out what it means. Actually there should be a GUID. Here is the article/question reading data from a USB port which may help
