checkdgt v1.3

checkdgt is a feature-rich checksum/check digit tool that includes verification/generation tools for many commonly used algorithms such as Luhn, Verhoeff, and Damm. There are also tools to generate and verify credit card numbers, scan and search UPC barcodes and ISBN barcodes, and verify Vehicle Identification Numbers (VIN).

checkdgt is an excellent solution for Software Testers who need valid test credit card numbers to use in testing, as well as anyone interested in learning about or testing many other check digit systems. Each check digit system also includes a short summary of its uses and how the check digit is calculated.

Additional utilities include a QR code scanner and ISBN/UPC product search.

NOTE: Credit card generation functionality should only be used for testing and educational purposes, do not attempt to use the numbers generated by this app to make purchases.
