General troubleshooting steps are found in the EMV pin pad setup at the end of the web page.

If you activate a pinpad, you should see 6 entries spread out in the web listener log that might help identify where things are in the communication process. These are:

1. the activation of the pin pad
2. a payment validation receipt with the request id - saying that we are going to request the CUSTOMER receipt
3. a payment validation receipt with the SAME request id - saying that we are going to request the MERCHANT receipt
4. a notification that the CUSTOMER RECEPT was retrieved (matching the request ID in step 2)
5. a notification that the MERCHANT RECEPT was retrieved (matching the request ID in step 3)

The above messages are followed by a housekeeping message indicating the number of receipts processed and the number that had an error. Normally, that is 1 processed and 0 in error (unless it is declined for some reason)
