In this live demo, user can type in any valid card number and card type. He can choose any customer ID (kind of unique number you can use upto 10 digits). Once you enter this input, select the tokenization button to generate the token number. This token number will be 25 digits long, which will be equal to CCNUM field.

You can select "Decrypt" button to arrive at the original card number. "Reset" button will make you start another set of testing live tokenization.

You can simulate the same tokenization and decryption for the same card number, but by varying unique customer ID. In other words, you can use the same card number in many sub-division of your company by assigning unique division ID so that different departments can have different tokens for the same card data - providing you extra security.
