Well that was fun. Did my first transaction today for £110. Customer, an elderly lady was very impressed by the terminal. Anyway i keyed in the £110 and obviously forgot to push enter. I then gave it to my customer to put her pin number in and then push enter. Looked at the screen and her 4 numbers had gone on to the total, giving a grand total of over £110,000!! Anyway, between us we worked out how to cancel the transaction and start again!
