Costco Pay fob for gas

Does anyone know what kind of tag is it? Google doesn't return any information at all.  I want to clone a copy, so I can give to my wife as well. Both hf/lf did not return anything.

Re: Costco Pay fob for gas

Interesting..  first few times that I did it, I got the following:

pro> hf search

#db# Multiple tags detected. Collision after Bit 2

no known/supported 13.56 MHz tags found

pro> hf search

#db# Multiple tags detected. Collision after Bit 1

no known/supported 13.56 MHz tags found

Now I ran it again, I got this, but when I do hf search again, it's back to the same result, where no tags found.
