Mifare Ultralight data
Mifare UltraLight cards have 512-bit EEPROM memory, which is organized in 16 pages with 4 bytes each. These are
low-cost contactless smartcards that do not offer any security features. The Mifare Ultralight C authentication is not
supported.
Specify the following parameters;
Page number
Page number to start reading from (in range from 0 to 15).
Always 4 pages are read. The reading will wrap around to page number 0 if additional data after page 15 should be
read.
Data length
Number of data bytes to read. The maximum number of bytes depends upon operating-mode and frame-length.
Data offset
Number of data bytes to skip.
Example
Data to read:
MIFARE UltraLight data
Byte order:
Normal byte order
Page number:
4
Data length:
8
Data offset:
2
In this example the reading starts at page 4. The first 2 bytes are skipped because the offset is set to 2. The following 8
bytes are read from the card as configured data length is 8
Driver-ID = 0102030405060708.

Reverse example
Data to read:
MIFARE UltraLight data
Byte order:
Reverse byte order
Page number:
5
Data length:
6
Data offset:
1
In this example the reading starts at page 5. The first byte is skipped because the offset is set to 1. The following 6
bytes are read from the card. Finally, the bytes are reversed
Driver-ID = 060504030201.
