C#

Hi,

I have a card reader for read a user card but reading appears that:

<b>For user 7196: %00007196_ç00007196_ - this is a new card</b>

<b>For user 910202: ç00910202_ - this is a old card</b>

Another card reader appears:

<b>For user 7196: 00007196 - this is a new card</b>

<b>For user 910202: 00910202 - this is a old card</b>

The problem is when i pass the card the system sends all codes like a copy-paste but i need control this paste. Eliminate chars, etc...

This code receives all ps/2 codes:
