I have a client with a spotty satellite connection. Many times they will have credit card transactions time out, apparently due to the internet connection being dropped. This results in 2 problems:
- Each successive attempt to swipe the card results in a I/O Failure 602 (the port is in use). The only way to get rid of this is to restart the POS program and "unlock" the port.
- Even with a manually entered verbal authorization (CC#, exp date, and authorization code), the user will STILL get a failure 602 error. I was under the impression that entering the approval code would bypass the need to contact the payment server and simply add the transaction to the batch. Again the only way to resolve this is by closing and restarting the POS program.
We've been insisting that these problems are due to their terrible satellite connection, but without hard evidence to back it, it's our word against theirs. If anyone can shed some light on this, it would be greatly appreciated.
