Hi,

I am trying to develop an app that store value into the card. I am using VB6 Sample Code supplied by the ACS reader.

I write a value (number) into Sector 3 Block 3. The write is not succesfull , there is error
"Unknown Reader Error : 3040"
. After that, i can not login into the Sector 3 anymore. There is error
"Operation Failed : -3030"
.

Why this is happening ?
Which Sector is safe / recommended to write, which is not ?
+ 0  |  - 0
