From VISA FAQ page on Buxx card, a card meant for teens with parental control of usage.
"Is identification required to use the card?
As a security measure to protect the teen, a merchant might ask to see a teenís ID, which could be a school ID or a driverís license. If the teen doesnít carry ID, the merchant can match the signature on the back of the card to the teenís signature on the receipt. "
The language of this answer is suggestive that asking for ID is ok, sends a false message that its acceptable for merchant to require ID and signature checking is secondary.
What idiot thought its okay to write the plain English version of answer in a misleading language?
It should read that "Some merchants may ask for an ID, but it is up to your teen to present it. Merchants can't require ID from your teen for using their VISA unless it is also required for every customer no matter the payment method"
