In reply to JM:
Interesting thought about a cashless society and to be honest it probably will become the norm sooner rather than later.
Just thinking at present I can go weeks/months without seeing cash. I don't even have a wallet just a mobile and a bank card in my pocket.
The vast majority of my payments are
Chip and Pin
Contactless
Paym (mobile to mobile money transfers)
Specific App that can be preloaded with money etc. Lunch time at work I like to eat at a certain places that have apps that you load with money. To pay you then just scan the barcode on the phone screen saves having to carry a wallet or cash etc.
Paypal I have been in loads of shops that allow you to pay with paypal at the till
Mobile card readers (I have been to many markets recently were the stall holders has a card reader attached to mobiles)
Bank transfers great now that all banks use faster payments etc
When parking in Liverpool city centre I pay using my mobile, no need for cash just phone or text your car reg and bingo parking is sorted.
Then cash after that. The only time I really carry cash is on a night out but I have found myself asking more and more retailers if they accept card or phone payments. If they don't I usually move on. However living in a modern city the majority of places permit a near enough cash free lifestyle.
Heck I don't even need cash to take the bus or train anymore plus lots of taxis are now accepting card payments.
Cashless society, one day it might be the reality.
