Hi,
Does the Ultralight EV1 have unique chip UID? I mean that 14-digit number is unique chip UID? For example 04FA90838730K3, 04FA9083873089, 04FA9083873090.....
The customer wants to use chip UID "04" 14 digits number one. I have read the specifications and it said unique, but the customer would like to confirm again as their system does not support repetitive UID.
Thank you
Best regards
Bonnie
