I have a R20D-USB RFID reader. When I connect it to the machine, open a text editor application or and webpage with an input form, and read the RFID card the RFID is automatically typed in the text editors/input form. (As I found out to use other RFID readers, we have to develop a script to read the input from the port and insert into our application)
How does R20D-USB RFID reader (uses RS232 port) read directly into text editors/input forms?
I need a technical explanation.
