hello leena..

ur are right..the datasheet which u have read, doesn\'t
reveal about psc verification..

its ok upto reading on card..but before writing on card u must do psc verification which is two bye code..default code on card psc=( 0xff,0xff )

their is particular sequence for verification..
fisrt write error counter..
verify two bytes..
then procesed for writing..

just take care while verification....after 7 wrong attempts it will block the card permantely..

this card is based on standards: ISO 7816..
i2c smartcard is totally different from this..
