I recently managed to reverse engineer a POS RFID card reader attached to a touch screen.
Now I want to go deeper and use it in a Flask enviroment as a quick form of local user login authentication. But is it realy possible for a flask webb app to recieve data from such an external device on client side ? How could server get the data from a client browser that might not even know of the existence of such a device ?
The RFID reader does not simulate keyboard presses. I need to control it by HIDAPI package which writes and reads specific packet data.
