Why do checkout lines start backing up in cashless society trials?
In cashless society trials, the process works, but checkout lines start backing up because participants can never find their card and their purse and so forth. The trial shows a cashless system functions, yet human difficulty locating payment cards creates delays at checkout.
Les explains that areas in America and Scandinavia tried a cashless society, testing whether a community could go 30 or 60 days without ever using a checkbook or a billfold. The trial worked, but the only problem they had was that the checkout lines started backing up because the people in these trials could never find their card and their purse and so forth. He uses this as an example of how a cashless system can function while still running into practical human problems.
