AOL will offer a system that stores key purchase information, such as a user's credit card number and preferred shipping address, that can be recalled instantly when a user is prepared to buy a product via the AOL service. AOL will offer a system that stores key purchase information, such as a user's credit card number and preferred shipping address, that can be recalled instantly when a user is prepared to buy a product via the AOL service. The company plans, in the coming months, to test the digital wallet service initially with a handful of retailers before expanding the service throughout AOL, said Senior Vice President David Gang. "This is something we would like to have in place before the holiday shopping season," he said. The idea behind the service, likely to be marketed to AOL subscribers under the name "Quick Check-Out," is to remove a stumbling block to completing merchandise transactions online. AOL estimates that 79 percent of its subscribers have used the service at least once to browse for products online; however, less than half of its subscribers have taken the next step and carried out purchases online.
