Cash will remain king......or will it?

According to an article just published by KAL Software: "Every time a new way of paying for something has arrived – credit and debit cards, internet payments, contactless cards,mobile phone payments – the imminent death of cash has been announced. It sounds a reasonable prediction to make given the convenience of these new methods."  Written by Peter Jones, the article maintains that cash remains well used in a mixed economy of competing payment methods.  It seems that people get 70% of their cash from ATMs, which reduce the cost to banks of dispensing cash by 80%, and can also be used to cut costs further.  I can't argue with that.
