摘要

The transaction system delivers a secret code unique to each transaction. The code is provided by the purchaser to uniquely identify them. The code can be generated from an electronic unit with a key pad and a screen, or alternatively with a personal organizer. The code generation function is accessed after a personal code has been entered by the user.
