The original translation, while correct linguistically, sounds a bit clumsy, like a literal translation. The suggested translation is "card year" rather than "expiration year", but people will know what it means.
Geçersiz bir son
a erme yılı girdiniz.

This version is the actual terminology (expiration date) but it's slightly longer.
