Cat (not-)scan

I got an RFID reader and demo kit from CoreRFID. This low frequency (125 kHz) reader works as a USB input device so requires no special drivers — the reader simply appears as a virtual keyboard.

This is how it appears to Linux:

[1282173.577869] usb 1-1.1: new low speed USB device number 19 using ehci_hcd
[1282173.684076] usb 1-1.1: New USB device found, idVendor=1241, idProduct=e000
[1282173.684084] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[1282173.684090] usb 1-1.1: Product: USB Keyboard
[1282173.684094] usb 1-1.1: Manufacturer: HOLTEK
[1282173.698805] input: HOLTEK USB Keyboard as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.0/input/input12
[1282173.707123] generic-usb 0003:1241:E000.0001: input,hidraw0: USB HID v1.10 Keyboard [HOLTEK USB Keyboard] on usb-0000:00:1a.0-1.1/input0

So far so good, it reads the four demo RFID tags that come with the kit perfectly.

However the real reason I got this was to try and scan the microchip in my cat.

Everything I read online seemed to indicate that these are 125 kHz RFID chips. But this reader can’t seem to read it …

    Hi, I think for animals is used 134 kHz RFID frequency.
