3.4.5. Reading a long string from a Mifare UltraLight card
Note :
This option is only available on Prox’N’Roll RFID Scanner, RDR-K632 and
ProxRunner.
When bits 4 and 6 in TOF.MIF are set (ASCII output, long string reading
extension enabled), the reader behaves as follow :
•
The output length (bits 0 to 3 of TOF.MIF) is ignored,
•
The reader reads sequentially all Mifare data blocks starting at address
specified in LOC.MIF (absolute address or pointer found in MAD), until
one of those events occurs :
o
The end-of-string character (‘\0’ i.e.
h
00) is read,
o
The end of the card is reached,
o
16 pages (64 bytes) have been read.
Doing so, the reader is able to return ASCII strings up to 64 characters
16
.
16
Well, not really, as Mifare UltraLight currently features only 64 bytes of data, with only 48 bytes
actually usable to store data.
