SMART CARD READER
When the power is switched on it will display SMART CARD on the terminal
(hyper terminal). This indicates that the smartcard reader is ready to work.
After getting this display message on the terminal if you insert a
smartcard green led(ln2) will be glowing.It will check whether it is inserted
properly or not. If not, it will display the error message like “Please insert
the card properly”. If you have inserted the card properly it will prompt you
to enter password which is called as security code.
Enter password:
Now you have to enter 3byte password.
NOTE:- Default password in SLE 4442 will be in hex format “FF FF FF”. By using
X-CTU we can change the default password.
Here the password is nothing but 3 byte reference data in the SLE4442
smartcard. So we must enter 3byte password (security code) here.
If you enter more or less than 3byte of password then it will give error.
Wrong Password:
If the password length is 3bytes and it is a wrong password or inserted
card is blocked then it will display
Card Error
If entered password is correct then it will display.
Card Accepted
If the password entered is correct then the middle led(green) will glow for three
times.
NOTE:-We have three led’s on the two green led’s(ln1,ln2) and one is red. RED is
for power indication, if smartcard is inserted then green led(ln2) will be glowing,if
the password entered is correct then the middle led(ln1) will blink for three times.
Now you can perform all operations on the inserted smartcard including
read, write and erase.
This reader is designed for SLE4442 type of smartcards. These smartcards
consists byte-wise addressable 256, 8-bit EEPROM. Here in these 256 (0 to 255)
bytes the starting 32 (0 to 31) bytes are protected bytes which consists some of
manufacture data like ATH (Answer To Reset), ICM (IC Manufacture identifier), ICT
(IC Type). Remaining 224 bytes are user configurable (read, write and erase)
bytes.
Additionally to the above functions the SLE 4442 provides a security code
logic which controls the write/erase access to the memory. For this
purpose the SLE 4442 contains a 4-byte security memory with an Error
Counter EC (bit 0 to bit 2) and 3 bytes reference data. These 3 bytes as a
whole are called Programmable Security Code (PSC). Only after a
successful comparison of verification data with the internal reference data
the memory has the identical access functionality of the SLE 4432 until the
power is switched off. After three successive unsuccessful comparisons
the Error Counter blocks any subsequent attempt, and hence any
possibility to write and erase.
COMMANDS: -
1. READ <M> <N> - To read the smartcard memory from 32 to 255 bytes
READ - Command
M - Starting memory location
N - Number of bytes to read
EX: - READ 32 13
O/P: - This is NGESC
Where “READ” is the command to read data from smartcard.
“32” is the starting memory location to read.
“13” is the number of bytes to read.
Remarks: - If you have entered the memory location which is less than 32
or greater than 255 or if you enter wrong number of bytes to read it will give
error as given in the below
ERROR
2. WRITE <M> <STRING> - To write data into smartcard memory from 32
to 255 bytes
WRITE - Command
M - Starting memory location
STRING - Data to be written
EX: - WRITE 32 This is NGESC
O/P: - OK
Where “WRITE” is the command to write data to the smartcard.
“32” is the starting memory location to write.
“This is NGESC” is the string which we are going to write into
smartcard.
Remarks: - - If you have entered the memory location which is less than
32 or greater than 255 to write, it will give error as given in the below
ERROR.
3. FORMAT - To format the entire smartcard memory (32 to 256)
EX: - FORMAT
O/P: - Format Completed
4. SET PSW <old password> <new password> <new password>
-To change the password (security code) of the smart card.
EX: - SET PSW ngesc - nge
O/P: - Successfully set the password
Where “SET PSW” is the command to change password (security
code).
Remarks: - If you enter wrong password it will display error as given in the
below
Wrong Password
If you have wrong command format it will display error as given in
the below
ERROR
NOTE:-Default password in SLE 4442 will be in hex format “FF FF FF”.By using XCTU
we can change the default password.
5. READ SMEM - To Read Secured Memory.
EX: - RSMEM
O/P: - ATR HEADER: 162 19 16 145
ICM: 129
ICT: 21
Where ATR - Answer to Reset Header
ICM - IC Manufacture identifier
ICT - IC Type
6. READ PBITS – TO READ PARITY BITS
EX:- 000011001111
