Thanks :)
By reverse engineering I'm not talking about the card, but the access scheme set by the company that handles our security cards. Thing is they'll take upward of $50 for a keyfob I can make for less than $1. As the card readers aren't connected to a central server they're not checking uid and they're not logging anything. If I can reverse engineer the scheme I can set up fascilities for our janitor to create keyfobs and save the building cooperative (?) a #¤%load of money :)
