Awesome

Perfect for making backups to your fobs.

Work great to copy 125mhz card keys using the keysy

These key cards are nice and thin, thinner than most standard-issue HID badges with laminated photo card. If you have one of the really old (10? 15 year?) beveled-edge badges then youre in for a treat -- this is just half the thickness. They programmed perfectly in one try with the Keysy writer, and work on every card reader. No batteries, of course, so I expect them to run forever. Were good here!

Great alternative to the battery powered device if you just want to leave some cards in your bag or card.

When my family came to visit me (7 people), I made 2 cards for them. My building not only charges 100USD each card, but they also explained to me that I already had 2 cards and that I couldnt have more. LOL 1 problem: Most of the building keys are white, so its easy to identify the hacker the is cloning access cards. They dont appreciate when you remind them that their whole access control scheme is homeopathic. If I ever lose one of these keys and I feel my serial code might be compromised, I would absolutely report it to the community management so they deactivate the card. Ill get a new one and make copies for my convenience. Just like a normal key.
