and if you try YOUR real card, you will get an error, so u know your card has been "hacked"...
u need to reinitialize your real card, and when the "hacker" come back, it don't work anymore...
I don't know if u understand what i mean, quite difficult for me to explain such things in english...
but u need to change the key on your rfid tag each time u'r using it, and u need a storage (TF shield) to store the new keys...
a0000 -> a = user1
b0000 -> b = user2
u got it?

great you just took a relatively secure safe and made is unsecure

@stdavross666 Why is that? You don't think the 125kHz EM-MARINE RFID system is secure?

@mindthomas
125khz is really unsecure...
A way to secure it, like i do with my webapp for iphone :
u need to change something everytime u scan your card..
First scan, the card contain the code "a0000", when u scan that card, it become "a0001" and so on...
u just need a database like on the arduino to compare the rdif card with it.
So the concept is that, if someone copy your card, and use it before u, let's say it change the "a0001" into "a0002", your real card is still "a0001"...

@Shinika01 You can't write and save data to these 125kHz EM-Marine RFID cards - they contain a unique ID, programmed by the manufacturer!

nice, but it had been more cool if you had connected the safe´s keypad and LED's also, and place the RFID-antenna behind the front panel.

@EcOEcOEcOEcO Yeah indeed. Though it would have required much more hacking, as the keypad is directly on the PCB with the locking chip too. But I might do that sometime ;-)
