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

I would either dynamically add +15-20 years to the current date's year OR provide a textbox input for the year (which personally I find faster to type the two digits in than to scroll through a list of years).
