What standards for RFID chips in pets?

1

My other half has requested an RFID-activated lock on the cat flap, due to incursions by other animals in the area.

Does anyone know whether the typical 125kHz RFID modules are capable of reading the chips in cats? What sort of ranges are possible, and is it relatively easy to build a high-gain antenna such that I can detect a cat within a foot or two without waving a wand all over its body?

In this project, the maker supplied their own RFID tags to hang on collars of the respective animals.

ISO 11784 and ISO 11785 - Wikipedia

One of the tags for my cats is 982xxxxxxxxxxxx (a 15 digit number), indicating that it conforms to the ISO 11784 standard.

ISO 11784 and ISO 11785 - Wikipedia

Indicates frequencies of 124–135kHz for these chip types.

Seeed studios wiki page indicates their readers use EM4100 protocol, not ISO 11784/etc.

Here is a reader/writer with RS232 (and looks like holes for a TTL interface) that handles the FDX-B and HDX animal identification tags.

No help I’m sorry, but a great project that should make you a fortune, there has to be a market for that. Owen
