smart card write error
Mar 27 2014 2:47 AM
hi,
i am working in smart card development. i have created MF (Master file), DF (dedicated File), EF (Elementary file) in smart card. EF file is used to store the data. This EF may be transparent file or record oriented file. i have written the data to transparent file using 00D1000008 540100 5303 010203 this command.i am also try to write the record oriented file using 00DD000008 540100 5303 010203 this command. but i got the error (6700 error code) wrong length. i need solution to write the smart card EF record oriented file. please guide me.
Screen shot:
i have used winscard.dll
