The accuracy of captured data from a coupon scanline is extremely important.
For this reason the coupon scan line should include check digits if possible.
This check digit calculator allows you to quickly test a check digit validation
against your scanlines exactly as they are calculated in the Aqurit product.
For more information on any of the steps that go into a check digit
calculation, click on the blue title of the step.
Internet Explorer with vbScript enabled is required to use the check digit
calculator
