Retail of the future

I've been thinking about the future of retail.  You will need some sort of  account to conduct business. You'll have to log into an account and the transaction will be stored electronically.  Or just by passing through the door your id will be scanned with a time date stamp.  Anyhow I haven't really played with the idea much.   I'm just trying to decipher a strange dream I had recently.  The customer and employee where separated by a computer terminal.  Business was conducted through the computer not direct human to human contact.
