Play date cards

Sorry deleted previous message in error. From Beckah Floyd, it read:

Hi guys,

Have you heard about these Streetcards play date cards you can get? They are supposed to make it easier to arrange play dates for kids.

 I was just wondering what you thought of them?

You can have stuff like photos of the child on them and all your contact details. Do you think they would be safe?

People misplace things all the time.
