Toronto’s parking meter boxes were like this. They just had GPRS so they’d do an overnight dump (possibly a part of their data deal with the telecom back when data was actually saturated during the day). So people were using cancelled or empty prepaid visa/mastercards. Initially they’d just push out blacklists. Once they really caught on, they did a firmware upgrade to do online verification and it took fooooreeeeveeeeerrrrr to do a credit card purchase.
