# ATR\_analysis(1p)

analyse a smart card ATR

## NAME

ATR\_analysis - analyse a smart card ATR

## SYNOPSIS

**ATR\_analysis** \[*ATRstring*\]

## DESCRIPTION

**ATR\_analysis** is used to parse the ATR (Answer To Reset) sent by a smart card.

The command also tries to find the card model using an ATR database stored in a text file called *smartcard\_list.txt*.

The *smartcard\_list.txt* file is searched in  *$XDG\_CACHE\_HOME/smartcard\_list.txt*, *$HOME/.smartcardlist.txt* and */usr/share/pcsc/smartcard\_list.txt*.

Example:\
  $ ATR\_analysis '3B A7 00 40 18 80 65 A2 08 01 01 52'\
  ATR: 3B A7 00 40 18 80 65 A2 08 01 01 52\
  \+ TS = 3B --\> Direct Convention\
  \+ T0 = A7, Y(1): 1010, K: 7 (historical bytes)\
    TB(1) = 00 --\> Programming Param P: 0, I: 0\
    TD(1) = 40 --\> Y(i+1) = 0100, Protocol T = 0\
  \-----\
    TC(2) = 18 --\> Work waiting time: 960 x 24 x (Fi/F)\
  \+ Historical bytes: 80 65 A2 08 01 01 52
