The TCFWcard!


I wonder if my Fivestars rewards card will still like this?

When I first scanned it, the user data areas were all just blank. Fivestars likely just uses the card id number as a user id token and that’s all.

I still like to imagine somewhere a server is getting mad and leaking a rainbow of colorful pastel suds, of course.

At least I was nice and didn’t turn it into an SQL injection card. Yes it’s been done.
