Desfire Magic Card

I currently have some Desfire UID magic card with me. I will verify with some other users in the forum on how good are they.

I will only put it on sale after some verification with some users.

The very few first desfire UID magic card even created. UID only can be change with our in-house software so we will only release on sale with limited sets with device and software with cards. Probably 50-100 sets. Purely for research purposes.

Stay tune.

Any questions please post on this trend.

Re: Desfire Magic Card

The card is not stable yet. There are some bugs. We are only able to clone the UID of the card. In order for it to work, you probably still need the key to access to the original cards to extract the blocks inside.

It is more for research card.

Re: Desfire Magic Card

This may be a silly question.. but: how would you go about actually writing the UID to the card using the pm3? Is there a custom firmware that supports that functionality?

I see the site says "Only in-house software with reader able to change the UID.", but does that mean we would have to send the cards off to you in order to be rewritten?

Re: Desfire Magic Card

Well. Obviously pm3 has the functionality to change the UID but you got to know how.

I can give a discount if you order more cards with the magic command to change the UID.

I am left with only a couple of the cards.

Re: Desfire Magic Card

I don't have magic cardd but I'm wondering how the magic mifare classic/ultralight/desfire cards work. Are they
1)A microprocessor card emulating the real card (with UID changeability)
2)Chips from a certain manufacturer that are found to have a backdoor
3)They are chip that are not already locked (On normal RFID chips the UID is written then locked when testing the wafer)


Those who forget the past are doomed to repeat it.
