AUTHENTICATION OF E-COMMERCE TRANSACTIONS USING A WIRELESS TELECOMMUNICATIONS DEVICE

摘要

An e-commerce transaction is conducted between a merchant system and a telecommunications device on a consumer's account. The merchant system obtains authorization from an authentication device of the consumer before completing the e-commerce transaction. A registry server, accessible by the merchant system, may be used to maintain a database of telecommunication devices authorized to conduct e-commerce transactions on the consumer's account.
