Project Description:
We have a C# program to communicate with the serial port SWIPE card device.

We are having issue like the swipe device responds to the first message but further messages its giving error.

we have used other programs from CNET.com to communicate and the swipe device
communicates very well NO ISSUES at all.

We can show you the program and also give you a remote connection to sort this out.

It should be very simple who have been working with serial ports.

Skills required:
