Topic: Xfailed to write trailer block - what's wrong ?
Hi,
I've got blank MIFARE 1k cards and can read all blocks. But when I try to write the data to the card I always get an error:
Connected to NFC reader: ACS ACR122 0 / ACR122U103 - PN532 v1.6 (0x07)
Expected MIFARE Classic card with UID starting as: dc0b86bb
Found MIFARE Classic card:
ATQA (SENS_RES): 00 04
UID (NFCID1): 07 be 52 28
SAK (SEL_RES): 08
Guessing size: seems to be a 1024-byte card
