One very painful case is credit card spending in the run-up to major
holidays, such as Christmas, where the credit card companies feel the
need for central authorisation of all transactions to reduce fraud. Fraud
is, naturally, at its peak at these times. The price of wrongly refused
transactions is also high, because it means customers march out of shops,
having wasted retail staff time.
