Great for individual ID badges

Recomendado

The mifare chip worked fine. The problem was that I printed an ID badge. Every print came out bad with things missing where the chip pressed the roller. If you print on these they look bad, which is especially bad if you use a barcode as well. If you look in the picture you can see the texture is not good, but can actually see the Mifare chip and antennae. All are like this out of 100 cards. The wireless is fine, it is the actual PVC card that is an issue.

I received what looked like very old inventory, the box was partially collapsed and wrapped with tape. The cards inside were individually wrapped as advertised so I did not send them back. I SHOULD HAVE. I registered these cards to an access system along with 100 from another vendor, all of the cards that I purchased from the other vendor registered flawlessly without any problems, but with these cards I needed to place them extremely close to the reader, sometimes having to touch the reader itself before it was recognized, and one card would not register at all. I expect to have problems with these cards working down the road and I will not by from this vendor again.

Only Half of Order Came & It Arrived Damaged

The listing describes these as read-only. In my batch (100 cards), they were MIFARE Classic compatible (Fudan FM11RF08S) with default keys and writable sectors. I was able to write to non-manufacturer blocks successfully. Buyers needing true read-only cards should verify before purchase. Otherwise good cards and compact packaging, vinyl stickers stay on and are very easy to apply.
