When they scan the card at the entrance to a place does it bring up your birthday or anything?
We have family membership. My 19 year old daughter and her boyfriend really want to visit somewhere but they're skint (they're going to buy lunch so will be making a contribution to the place which they'd otherwise not visit as they can't afford it).
If they used my husband and my cards, would the person working there just see Mr & Mrs Plops and let them in?
