Maximum Year in Expiry Date of Credit Card

Question

Various online services have different values for maximum year of expiry, when it comes to Credit Cards.

For instance:

• Basecamp: +15 years (2025)

Answer 1

If you want a solution that does not yield three-digit years 2100+ you must modulo the date, accordingly you must fill with leading zero for xx00-xx09 years to not get single digit years.

This will be very important starting in 2080.
