That's fun - can you see the antenna they mould into the plastic?

There's no antenna, contactless payment cards are pretty uncommon in the US.

There is an Amex clear card with antenna. They kind of built it into the design. I can't remember which one is was though.

I have the Canadian Amex Simply Cash, it's clear and has an antenna for contactless payments
