In Citigroup (NYSE:C - news)'s most recent annual report, the world's largest financial company began its list of achievements in 2006 with its launch of a biometric credit card in Singapore.

Meanwhile, shoppers at several Shop 'n Save supermarkets in Pittsburgh are signing up for SmartShop, a card-based loyalty system that directs special offers to each customer based on their previous shopping history
"Both Shop 'n Save and Citi are using technology developed by Pay By Touch, a rapidly expanding privately held company that wants to shake up a global payments industry dominated by Visa, MasterCard and American Express."

Supervalu, the second largest traditional US grocer, remains the system's largest client, although a senior executive from the UK's Tesco last year highlighted Pay By Touch's system in a review of new payments technology - noting in particular the potential for integrating biometrics into its current ClubCard loyalty scheme.
Several factors lie behind the surge in interest. The biometric system still allows a customer to choose from an "electronic wallet" of payment methods, such as direct debits, credit card accounts, or state food benefits.

Beyond simple payments, Pay By Touch has sought to move further into customer loyalty with its SmartShop technology - which uses proprietary software to offer weekly incentives and special price cuts to an individual customer based on their shopping habits and preferences.
For retailers, the system offers a way to direct offers effectively to their most loyal customers, rather than supporting "cherry picking" of bargains by customers who only buy the offers.

"Our data suggests they're doing more of their shopping at the store where they're getting their offers," says Mr Morris, a veteran of IBM.
Pay By Touch now has about 800 employees and is largely unchallenged by biometric competitors, since it acquired its main rival in 2005. It has also won over $300 million in financial backing, including support from Ron Burkle, the billionaire investor who made his reputation in retail
