Pay By Touch -- the company behind the fingerprint scanners in supermarkets like Piggly Wiggly and Albertsons -- is planning to make biometric payments the norm on the web as well. The company's new service, Pay By Touch Online, aims to create a standard for biometric hardware and software. Pay By Touch says it expects to certify millions of scanners this year, and that its service "diminishes consumers' fears and increases customer satisfaction" by allowing customers to use a fingerprint instead of a credit card to pay for online purchases.
