Back in 1998, ATM was still a new thing. Few people knew what it was; leave alone how it is used. I was in 7th or 8th standard, and was aware of how basic bank transactions work. Owing to me innate curiosity, I was more than eager to know how an ATM works. I would listen to friends of Uncle talk about it in awe, as to how one could withdraw cash from an apparatus in the wall, instead of the lengthy procedure we follow. Unfortunately, neither my uncle nor his friends knew the details or wanted to find out.
