Can credit/debit cards indicate age?

Question

If a minor attempts to buy salvia ,or any other herb of dubious legality, online can the company check their age though the credit card?

Answer 1

Sometimes it can. Some cards do have age verification but it has to be set up by your merchant provider. However, I thought herbs could be sold legally even to a minor. (Note-I am an adult)

Answer 2

Actually, no they cannot. I had a Visa card when I was 14 (and still have it). It is interesting that many web sites for pornography use a credit card to verify age. Age isn't actually verified at all. It is merely presumed that you must be at least 18 years of age to have a credit card.
