Cashless Society?

In a world of credit cards and bank transfers, vouchers and buses you can't even get on unless you've pre-bought your ticket it seems we're closer than ever to living in a cashless society.  But, is it possible to live a normal existence free of the bounds of paper (well, plastic paper) and metal tender?  We shall see.  The ninth month of 2008 will be Credtember (for lack of a better name) for me - all monetary transactions throughout the month will be virtual.  Obviously, the bigger transactions will be easier - nobody thinks twice about buying big-ticket items with a credit or debit card but the little things may well prove to be an issue.  To that effect, IOUs and tabs will be a valid form of purchase for Credtember (as long as the vendor agrees - the first tab secured is the morning coffee from Platos, the 1 Market St cafe that produces a very serviceable piccolo late and I'm hoping that their generosity will extend to the occasional sammich although I'm planning to minimise such inordinate expense by making my own luncheon which is usually preferable anyway).  I've also decided that little purchases can be made in cash, as long as it's not with my cash.  This may mean pushing the limits of various friendships for the month but most of my friends are aware of my strange and varied principles so they shouldn't be too perturbed.  Let's see how we go.
