RFID Tag Error

Post by zethra »

I just got the RFID shield for Arduino product 789 and the MiFare Classic Card product 359. I ran the mifareclassic_ndeftoclassic then the mifareclassic_formatndef sketch with no alterations with no issue. Then I attempted to read the card with the readMifare sketch and got this error:

Seems to be a Mifare Classic card (4 byte UID)
Trying to authenticate block 4 with default KEYA value
Ooops ... authentication failed: Try another key?

Can some one please help and explain why this isn't working?

mem dump output:

Looking for PN532...

Firmware ver. 1.6

You seem to have run these in the wrong order. The cards are Mifare Classic by default but you tried to convert from ndef to classic and then format as ndef.

What happens when you run ndeftoclassic again?

If I try that then the read program gives me:

Seems to be a Mifare Classic card (4 byte UID)
Trying to authenticate block 4 with default KEYA value
Sector 1 (Blocks 4..7) has been authenticated
Reading Block 4:
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

And mem dump:

This looks like a vanilla Mifare Classic (not NDEF formatted) card.

Here is a dump of a clean Mifare Classic 1K card:

Code: Select all

Found an ISO14443A card
  UID Length: 4 bytes
  UID Value: 0x3E 0xB9 0x6E 0x66

Seems to be a Mifare Classic card (4 byte UID)

When I take the tag above and I run the 'mifareclassic_ndeftoclassic' sketch and then do another memdump via 'mifareclassic_memdump' I now get this, which is a clean Mifare Classic Tag (factory default state):

ndeftoclassic output:

Code: Select all

Found chip PN532
Firmware ver. 1.6
Place your NDEF formatted Mifare Classic 1K card on the reader
and press any key to continue ...
Found an ISO14443A card/tag
  UID Length: 4 bytes
  UID Value: 0x7E 0xCC 0x6E 0x66

Seems to be a Mifare Classic card (4 byte UID)

Reformatting card for Mifare Classic (please don't touch it!) ... 


Done!

Which is similar to the output you have.

Running 'mifareclassic_formatndef' on this class card formats it for NDF data and writes an NDEF record:

Code: Select all

Looking for PN532...
Found chip PN532
Firmware ver. 1.6

PLEASE NOTE: Formatting your card for NDEF records will change the
authentication keys.  To reformat your NDEF tag as a clean Mifare
Classic tag, use the mifareclassic_ndeftoclassic example!

Place your Mifare Classic card on the reader to format with NDEF
and press any key to continue ...
Found an ISO14443A card
  UID Length: 4 bytes
  UID Value: 0x7E 0xCC 0x6E 0x66

Seems to be a Mifare Classic card (4 byte UID)
Card has been formatted for NDEF data using MAD1
Writing URI to sector 1 as an NDEF Message
NDEF URI Record written to sector 1


Done!
And the memdump gives me this where we can see the NDEF record:
