A credit card checker is a must have for retailers who rely on credit card sales to keep their business afloat. Unfortunately most retail stores are still using an old fashioned check system. Most stores still only print the last four digits of a credit card. To make matters worse, most credit card processing machines only read a tiny number of digits. This means that when a customer punches in credit card information it can take up to 10 seconds for the information to be processed. This can lead to long delays in the cash registers and can frustrate customers who are trying to pay for products while they are waiting.Credit card checkers come with a program which performs a complex mathematical algorithm to solve this problem. Windows Checker comes with its own patented algorithm that is based on patented algorithms developed by award winning computer scientists. The patented algorithm takes the customer's last four digits of any debit or credit card number and creates a unique checksum.
That is all there is to Windows Checker. It will perform the basic operation of a normal credit card checker, such as storing customer data in its secure server, generating and comparing unique checksums to verify the authenticity of a transaction, and reporting any discrepancies it finds. But the unique thing about Windows Checker is that it can also perform a more advanced operation called "linking". If a customer pays with a debit card and the check amount falls under a certain range, then Windows Checker will compare the range with a pre-determined range of other ranges using the luhn algorithm.
