I think L22 had a card, onto which payments were added.
The first year at JA's secondary school was when they introduced a cardless payment system - you're recognised by your fingerprints. On the one hand, eeek, on the other, you just know that losing your card is going to happen.
Until this school year,** if you ran out of credit then you had to go and borrow money from the Pastoral office. Next day, you were expected to pay it back in cash.
Now, you're allowed to go overdrawn on your account - as a parent you get a 'please top up the account' email.
It turns out that you're only allowed to go overdrawn if you start with some credit. So if you have 80p credit in the morning, and spend it all on a drink in the morning you're stuffed: because you have zero in your account, the system won't let you go overdrawn.
As well as emailing to say that's silly, my solution has to been to top up the account with £x.01 - as everything is priced in multiples of 5p, she will never have zero money in the account again...
