The bill could be a playable CD too if you don’t care about folding, or add bends around the central square. The widest rectangle that can be cut out of a CD and still retain a bit of the data area is about 108×51 mm, as opposed to approx. 156×66 mm of a $1 bill.
But yeah, NFC or just printing the data is more viable.
