We have come so far

Lmao ok not at 6 but my daughter was 11 and knew our card from memory so she could order something online.
But we fully trust her and we have a lock on the card so if we want to use it we have to punch in a code which she doesn't know and unlock the card.

I think My card starts with a 6...or a 4.....

Well if she starts exercising her memory early on, that's a good thing.
