This script will automatically recognize and dump full content of a NFC NDEF Initialized tag; non-initialized tags will be ignored.
|
|
|
|
It also write the dump to an eml-file <uid>.eml.
|
|
|
|
(The difference between an .eml-file and a .bin-file is that the eml file contains
|
|
ASCII representation of the hex-data, with linebreaks between 'rows'. A .bin-file contains the
|
|
raw data, but when saving into that for, we lose the infromation about how the memory is structured.
|
|
For example: 24 bytes could be 6 blocks of 4 bytes, or vice versa.
|
|
Therefore, the .eml is better to use file when saving dumps.)
