I guess this is a "money matters" question...
The other day my daughter (16) told me she'd forgotten she needed to take in some money (about 30 pounds) to school the next day, urgently of course! I couldn't make it to the bank before then and had no cash, so I could think of nothing else to do but give her my bank card and tell her the number.
My husband says I shouldn't ever do anything like this as the P in PIN stands for "personal" and the bank always tells you not to share your number. But I trust my daughter, and she has her own bank account she withdraws money from, so was in no more danger of being attacked or something than when withdrawing her own money. It was quite important and I couldn't go myself.
Would others do this, or do you also think like my husband that this is simply an absolute no-no?
