Payment Plus is still a new system with undiscovered wrinkles. Only errors that are reported can be fixed.

If you get an error message during a payment transaction – REPORT IT TO LIBRARY IT.

The preference is for a screen shot of the error message – image saved and sent is best, but at least print the page so that the error message can be reported accurately.

If you get a FATAL ERROR message during a transaction, do not repeat the transaction on the same or another PC. Report the error to Library IT at the first opportunity. Override the fine if necessary. It is likely that the transaction will still have gone through (but slowly due to poor network speed) and the fine payment made on both systems 10 or more minutes later.

Thank you for your vigilance
