I have some keytags with the following manufacturer block:
1. 4550ce65be0804006263646566676869
2. c7ba8023de0804006263646566676869
3. 37897123ec0804006263646566676869
Does anyone know who is the chip manufacturer for these keytags?
These keytags can't be broken by PROXMARK3!
Thanks in advance.
Dear Vasile Cadinoiu,
Hope you are doing great, I would like to know what is the purpose of trying to break the tags you mention, using the PROXMARK3.

It is known that 1k mifare is vulnerable to key and data readout. I make mifare 1k keyfob readers, which I use for building access systems. I'm interested that these keyfobs can not be cloned. We have tested several types of 1k mifare from several manufacturers. This type I noticed can not be broken with proxmark3, but I do not know who the producer is. That's all. Thanks for reply.
Dear Jonathan,
Have you a reply for my request?
Thanks.
