Some months ago I bought this 125kHz RFID Reader / Writer from eBay.
I was wondering how can I actually read or write an RFID Tag with it. So I attached it by usb to my computer (running Linux) and saw just this:
[786026.932028] usb 3-1: new full-speed USB device number 3 using uhci_hcd [786027.092100] usb 3-1: New USB device found, idVendor=10c4, idProduct=ea60 [786027.092107] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [786027.092111] usb 3-1: Product: CP2102 USB to UART Bridge Controller [786027.092115] usb 3-1: Manufacturer: Silicon Labs [786027.092122] usb 3-1: SerialNumber: 0001 [786027.262224] usbcore: registered new interface driver usbserial [786027.262243] usbcore: registered new interface driver usbserial_generic [786027.262257] usbserial: USB Serial support registered for generic [786027.267525] usbcore: registered new interface driver cp210x [786027.267546] usbserial: USB Serial support registered for cp210x [786027.267583] cp210x 3-1:1.0: cp210x converter detected [786027.376029] usb 3-1: reset full-speed USB device number 3 using uhci_hcd [786027.522286] usb 3-1: cp210x converter now attached to ttyUSB0
I tried to print characters to serial port
echo "blah" > /dev/ttyS0 but nothing is answered by the RFID reader ( with
cat /dev/ttyS0 ).
Since it's a chinese RFID Reader not much infos could be retrieved from internet. No usage specifics. Nothing.
I tried to search over internet the model name:
HL-208 but I haven't found anything that could help me reading / writing my RFID tags.
I also looked for that
cp210x and undercovered that is actually an USB to UART Bridge.
"Bonus" Question: How can I actually determinate which type of RFID tags are these? Is there anything I can do, except trying it with every single RFID Reader specific to the model, to determine which frequency and type they are?
