Visa number

[immihelp]

Hello,

I work in a clinic and I need help in interpretting a patient's visa card. Where do I find the patient's visa number? There are a lot of numbers and letters and I just can't find any information on what means what.

Any help you can provide I would appreciate it.

Thank you,
