If it indeed is the ultralight chip, there seems no encryption: "The disposable passes are cheaper Mifare Ultralight cards that do not employ any encryption or keys, and can be read by anyone."

Would spoofing be doable? I got my wallet full of cards for "all kinds" of things, that is, entrance to the office and subscription for the library. I guess these are linked to the chip ID (although I know of libraries that don't use the ID of their labels, if I understood them correctly! I asked a few times, under different angles of question-attack, but got the same answer each time. Unbelievable...). Does this kind of antenna need to have right-angled corners, as in the photo? Or is that shape easier sculpted in the PCB? Thanks for the experiment!
