read the memory content from a mifare and/or Felica

[PNamg.1295]

I would like to be able to read the memory content from a mifare and/or Felica tag similar to how the NXP tag detector app on Android does. How would I go about doing that?

I have implemented the demo polling example using nfc03a1 and a non st chip over SPI. When reading the Felica tag I get the UID and system code but I get "check block: FAIL". it seems this if statement is failing: checkRes[RFAL_NFCF_CHECKUPDATE_RES_ST1_POS] != RFAL_NFCF_STATUS_FLAG_SUCCESS in the rfalNfcfPollerCheck function.

this is the output:

For the mifare tag all i get is the UID. Would using ndef commands help me read their memory content?

Mifare is a proprietary protocol and can therefore only be supported by its manufacturer, see e.g. also here.

For FeliCa™ see e.g. there.

Hi,

Mifare: it depends, which variant: Mifare Classic is proprietary. Mifare UL / Desfire should be compatible (when formatted) to NFC Forum T2T/T4T.

This way they will be read by e.g. STSW-ST25R017 (ST25 Embedded NFC lib for ST25R95) using its ndef_rw project.

Resolved the Felica memory read issue by using the correct nfcid2 and the NXP_APP defined service code in the RFAL_NFCF header file.

In terms of formating Mifare cards, what does it mean to format a Mifare Desfire to NFC Forum T4T? Is it similar to formatting a hard drive from one file system to another? Would it still be recognized as a Mifare Desfire card in the NXP Tag Info app?

Thank you,

Palden

Hi,

regarding DESFire T4T formatting, see Application Note AN11004 (MIFARE DESFire as Type 4 Tag) from the manufacturer of this tag. If your application basically requires memory read/memory write only, I would suggest to use ST25TA tags instead of DESFire.for T4T and ST25TN tags instead of MIFARE UL for T2T
