Maybe they use recycled credit cards?

That doesn't explain why it's zeroed everywhere except for a few spots, though.

It's definitely re-encoded. There are words "FLEA" and "TICK" encoded on the cards for respective insects. My bet is on recycling mag cards by cleaning them up, cutting in three and reencoding.
