26kbps, modulation 10%, CRC automatically
added
02020200 – ISO/IEC14443A, 106kbps
transmission & reception, Frame Delay Time
(FDT) of 86/90µs
Frame Delay Time (FDT) definition: These 3
bytes are optional. When PP, MM and DD are
not specified or set to 0x00, the default value
corresponds to FDT of 86/90us, used during
anti-collision process.
Otherwise, the following formula applies:
FDT  ^{2PP  MM1 DD 128 32} [s]
13.56
3 7:0 DD (max 127, i.e. 0x7F)
If PP is defined, MM must be also set, but DD
still remains optional
