Jagdeesh, my colleague, told me an story one day. A doctor was travelling with his driver and they passed through a toll booth. Doctor paid 40 bucks as toll tax using his credit card and moved on. When he read the SMS, sent by the card issuer, around 15 minute later, he as satrteled. He has been charged 400 thousand bucks. Since his credit card has limit, the transaction went through. Although he came back and settled the things with toll company and his bank, I could never understand how that can happen. Well, not untill yesterday when I was about to pay 27 million. Of course, I do not have such limit in my card.
What actually hapened was that after entering the amount, the petrol pump attendant missed to press the enter button. As he handed over the swipe device to me, I entered the pin without looking at the little lcd screen. However, I happen to look at the screen before I pressed the enter button. I noticed the amount, took a moment to understand what has happened, and returned the machine to attendant to cancel the transaction. She looked at the amount, stranged look came on her face as if she has seen a ghost, and she immediately pulled out the card. I was relieved and saved.
The amount was 2704.83 and I after added 4 digit pin, it became 27048311.11 (pin changed to 1111). This is 27,048,311.11 i.e. 27 million. Although the transaction would not have approved because of insufficient limit in my card, it was a very good lesson for me.
- Always have a second look at the amount. You must know how much you are actually paying.
- Always look where are you typing and ensure that you are typing at the correct screen.
- Always press enter after you have entered your four digit pin.
