My 16 year old son has just phoned me from the cinema, asking me to send a photo of his passport so he can get into the cinema to see a 15 film. I've just looked up on the internet to find out about I.D cards, but there seems to be quite a few on offer. I'm not sure if they are all nationally recognised or if I would just be wasting my money. Has anyone already done this and was it accepted everywhere.
