Most high street banks are now using automated calls to alert customers to any unusual transaction and to ask them if they have made it.
Santander says it is making around a thousand calls a day just to verify cheque payments.

Free help to cut fuel bills
Four major energy companies are offering free home insulation to any householder. You don't have to be a customer of that firm and your personal or family circumstances or income isn't taken into account. It sounds too good to be true - but it isn't if you act quickly.
There is also more money going begging for updating heating systems but that is confined to low income households of particular types.
Paul Lewis talks to Jessica Forster, Energy doctor at the Energy Saving Trust to find out what deals are available.
Bankrupts not welcome, says Coop
If you're declared bankrupt but still need a bank acccount for your wages, your benefits or to manage payments, then your choices are now much reduced.
By fifty per-cent, in fact. From this week, the Co-operative Bank has stopped offering a bank account to new customers who are undischarged bankrupts. Which leaves only Barclays on the high street willing to provide them.
Paul Lewis hears from the Cooperative Bank's Head of Banking, Robin Taylor and talks to Mike McAteer, Director of The Financial Inclusion Centre.
