Obviously from the YAAMAVA' Resort & Casino, San Manuel, CA, but what exactly is it?

It feels plastic, but has a high-relief, wood-grain finish. It is also laminated, and is exceptionally rigid. It is the same size as a standard room key and slot card, but slightly thicker being laminated.

Most likely it is a room key, with an RFID tag/load inside.

But it could also be something else, like an employee ID or some sort of computer token, or???

Anyone? Anyone? ANYONE?
