5198f2e2 2THIS IS WORK IN PROGREESS, very much not finished.

4This library utilises other libraries under the hood, but can be used as a generic reader for 13.56MHz tags.

103 We start by trying this command:
104
105 proxmark3> hf 15 cmd sysinfo -2 u
106 0F C4 81 FF 70 00 01 04 E0 01 00 1B 03 01
107 UID = E004010070FF81C4
108 Philips; IC SL2 ICS20
109 DSFID supported, set to 01
110 AFI supported, set to 000
111 Tag provides info on memory layout (vendor dependent)
112 4 (or 3) bytes/page x 28 pages
113 IC reference given: 01
114
115 This command is not always present in ISO15693 tags (it is an optional standard command) but if it is present usually the tags contain all the "colored" info above.
116
117 If the above command doesn't give an answer (see example below):
118
119 proxmark3> hf 15 cmd sysinfo -2 u
120 timeout: no
121
122 we must send the MANDATORY (present in ALL iso15693 tags) command (the example below is sent to a tag different from the above one):
123
124 proxmark3> hf 15 cmd inquiry
125 UID=E007C1A257394244
126 Tag Info: Texas Instrument; Tag-it HF-I Standard; 8x32bit
127 proxmark3>
128
129 From which we obtain less information than the above one.
