Validation mask on credit card payment types

I would like to share my recent experience with latest install of RMS 1.2 SP3. This customer uses Preferred Acquirer Credit Card Processing. I have not set up validation mask on their credit card payment types at first. And I didn't have to wait long enough when one of their employees typed amount of the sale and swiped credit card in the Account number field. They were able to get authorization for the sale, but when time came to close the batch, they have to void the sale and rerun again with the correct card number. After that I typed in, suggested by RMS help, validation masks. This masking would eliminate most problems when first digit validated. However this kind of validation masking is a bit primitive. I am working with another POS software for the restaurants, and they validate card numbers by first digit, number of digits on the card, and it runs check sum on the number itself making sure the number is legitimate one. My hopes that RMS will take this in consideration for future fixes and updates.

Typically, credit card numbers start with a unique number. For example, MasterCard credit card numbers start with a 5. VISA credit card numbers start with a 4. If you want to separate the credit card tender types, you have to set up individual tender types for each type of credit card that the store accepts.

You can use the Validation Mask feature to prevent a cashier from accidentally selecting an incorrect credit card tender type when tendering a sales transaction.

To set up a Validation Mask for a credit card tender type, follow these steps:

In Store Operations Manager, click Tender Types on the Database menu.
Make sure that you have created a Tender Type for all the credit card types that the store accepts.
Select the first credit card Tender Type, and then click Properties.
Click the Verification tab.
In the Tender Verification area, type the appropriate value in the Validation Mask box. You can enter the Validation Mask in two ways. For example, if you are setting up a VISA credit card Tender Type, the Validation Mask can be entered in either of the following formats:? 4* When you use the unique credit card number identifier of 4 followed by an asterisk, Store Operations requires the first digit of the swiped card to be a 4. The remaining numbers are not validated. ? 4############### When you use the unique credit card identifier of 4 followed by 15 pound signs, Store Operations requires the first digit of the swiped card to be a
Store Operations also requires that the credit card contain 16 numbers. If the credit card does not meet the criteria that you enter for the Validation Mask, you receive the following error message: Validation Error 323: An invalid credit card number was detected. The following table lists the most common credit card types, together with the prefixes and the credit card number length.Credit card type Prefix Length

MasterCard 5* VISA 4* American Express 3* Diners Club/Carte Blanche 3* Discover 6*
