ICODE DNA freeze (No reply) until RF Off

Question asked by Patrick Soto on Nov 4, 2019

We use the ICODE DNA chip on inlays with our own RFID reader.

On some tags, sometime the chip doesn't reply on an addressed read single block command and after that, the chip seems to be frozen. We have to switch off / switch on the RF signal to return to nominal operation.

The freeze can also occur on a mutual authentication command.


This happens with several readers, several different environments and only on some chips.



Is someone experiments the same kind of issue with ICODE DNA?

What can be the root cause of a total freeze of the chip ?


Thank you for your help.
