Method and system for dissemination of paperless transaction receipts in non-networked environments
Abstract:
Electronic transaction receipts in remote non-networked sales equipment are sent through infrared or radio frequency means to portable electronic devices such as personal digital assistants (PDA's)/smart cellular telephones that are in the possession of the consumer. These portable devices are possessed by the consumer and are in very close proximity to the POS device transmitting the information. Security procedures also verify the receiving device to avoid inadvertent transmissions and to provide addition security for the transmission. The information and records received by these portable devices may be stored and uploaded into other electronic media at the discretion of the consumer.
