What are people using for electronic access control of pets?
I'm aware of a few antiquated "mag lock" solutions, but actually I am interested in the newer RFID, both collar based as well as microchip implant technology. Specifically how well it works, how reliable it is. For 2 cats ~10lbs each.
Here is an example of one unit I am considering, up to 20 pet registration, flexible scheduling and usb connectivity, though a relatively weak reporting module, by human standards.
