we have migrated recently from Mifare Classic to Mifare Plus SE and we have faced many issues of operating distance.
Acoording to application notes, we knew that the Hmin for Mifare Plus SE is 0.8 A/m against 0.25A/m for Mifare classic.
Now we are working on Desfire EV1 and EV2. I cannot find information about Hmin for Desfire.
Can you please give the minimum values for Hmin ?
