摘要
A method for validating and securing transactions involving multiple agents separated by physical space or scheduling constraints is presented. In the invention messages (informational tokens) are communicated at key junctures during a transaction (a transfer of goods or provision of services) to provide confirmation of the transaction to parties that are not present during the transaction. The transfer of informational tokens may occur by attachment to products or service related packages, through telephone, Internet or other inter-party communications channels.
