American Express (Amex) has developed a package of anti-crime measures to fight an anticipated 174% increase in fraud where the card is not presented by 2003.
European head of fraud risk management Joy Przeczek said use on the Internet of information culled from discarded till receipts was "the perfect opportunity for fraudsters to order goods and remain anonymous".
She said Amex had been developing sophisticated methods of spending pattern analysis, not only checking the location and frequency of sales, but also the type of purchase and whether it matched a card holder's normal spending habits.
Another check is being made on purchases for less than £50, which usually fall below the threshold for analysis by fraud management systems. Przeczek said Amex's systems would be combing records for evidence of fraudsters using fake credit cards to make purchases at petrol stations, just under the £50 limit.
Another tactic will be to refuse to allow the use of Amex on sex or gambling Web sites that have a poor record for confidentiality.
