Kinda. ;-)
5############### that's a 5 with 15 # after it. MasterCard starts with a 5 and has 16 digits total in it. Visa would be a 4 with 15 #, AMEX a 3 but with only 14 # becasue its a 15 digit card number, etc.
@ Jeff- Do you just add the 5 for mastercard in the validation mask field?
This has been a great discussion. I have checked with the client and this has only happened a handful of times, the CC has always been VISA. They had been running for years and never saw this and now in the past three months it has happened 6 times. I will follow your suggestions and see how it goes and update this thread.
Now that is interesting!
@ Richard, Correct in Tender types of your credit card tenders on the Verification tab.
@Jerry,
Some loyalty and club cards add the member number to the card number if track3 is enabled on the scanner. Costco AMEX and Sam's Club Discover cards as well as some Airline cards do this. If track 3 is enabled and a mask is not turned on, either the card will fail or it will self approve because of the extra numbers that look like a validation code.
Adding the mask prevents any extra numbers to be read, so it will always fail to process the card until the track 3 is turned off in the scanner and will not self approve.
Jeff, how does that help Richard?
Do I find these settings under Tender Types?
Make sure you have validation masks for your credit card tenders.
| Credit card type | Prefix | Length |
|---|---|---|
| MasterCard | 5 | 16 |
| VISA | 4 | 16 |
| American Express | 3 | 15 |
| Diners Club/Carte Blanche | 3 | 14 |
| Discover | 6 | 16 |
I just checked another receipt that did not get to the CC processor and the authorization number is there. The Perform Verification VIA EDC has always been checked. I will asked if it is a certain CC where this happens. Perhaps it is a Discover card that is causing this.
Probably not. It may be an issue with your merchant services, make sure they support discover and all that. Also have the clerks make sure they get an appoval # on the receipt for each transaction, sometimes that can slip through.
Good luck! You can also check the VisaNetAuthorization table in sql to look for it and see if there is anything funny there.
