Definitions

  • the present invention relates to electronic transactions and, more specifically, to a system and method for ensuring transmittal of payment and product in transactions. Relevant Technology
  • Electronic commerce is an expanding and dynamic form of business which is receiving growing acceptance. Although, the term "electronic commerce" is used loosely, it is frequently associated with transactions which occur over a network, such as the Internet.
  • Internet commerce is attributed with an ever increasing portion of various markets and is a popular method for performing transactions.
  • Numerous merchants have expanded into the Internet market and have noted the advantages in having an electronic presence. These advantages include reducing physical store location expenses and reducing inventory distributions to the various store fronts. Thus, merchants are able to consolidate their inventory in a central location and reduce expenses. Consumers enjoy the convenience in shopping on-line and avoiding crowds, parking, and difficulties in finding products.
  • Credit and debit card technology readily lends itself to electronic commerce.
  • An account number may be readily transferred over the Internet and verified.
  • a customer may enter or otherwise use the credit or debit card. Debiting or crediting is frequently performed first by the merchant before the customer receives the product. The customer is therefore at a disadvantage in that the customer has in effect transferred a payment before receiving the product. If the product is not sent or received, or if the product is received in unacceptable condition, the customer must seek recourse from the merchant or from the third party account holder. This is often an unpleasant and inconvenient task and may not remedy the situation to the customer's satisfaction. Alternatively, the product may first be shipped or otherwise transmitted and then the customer's account may be debited or credited upon receipt. This scenario is unacceptable for merchants who must send products without first having assurances of payment. Thus, transactions which are not performed at store fronts are not simultaneous in that either one party or the other receives their compensation first.
  • products may be embodied and sold as electronic signals, such as executable files, operational data, data structures, and so forth.
  • the electronic signals may constitute software applications which may be purchased and downloaded.
  • the electronic signals may also constitute various computer readable media such as text, audio, and video files. Such electronic signals are referred to herein collectively as product files.
  • the customer may receive and store the purchased electronic signals on the customer's computer for use.
  • a common issue in a transaction involving a product file is to ensure that payment for the product file is confirmed before the product is sent. Likewise, it is a concern to ensure that receipt of the product file is verified before payment is sent. Given that the transaction is entirely based on the transfer of electronic signals, one entity may withhold their obligation in the transaction while receiving the benefit. The transfer of electronic signals which constitute payment and product may provide an opportunity for unscrupulous individuals to take advantage of the system.
  • a further innovation in the arena of electronic commerce is the introduction of processor chip cards or "smart cards.”
  • the so-called smart card is capable of processing instruction code and has far more advanced memory capability than the traditional magnetic strip cards.
  • the smart card is able to process and manage transactions for a plurality of accounts stored on the card.
  • the accounts may include debit, credit, and incentive accounts, which may be redeemable for goods and services.
  • the smart card is capable of managing and maintaining running totals of the user's accounts.
  • a smart card user may therefore store multiple accounts on a single smart card and enjoy the security and convenience of the smart card.
  • the smart card may be readily integrated into electronic transaction technology. Given the benefits of smart card technology, it is anticipated that it will ultimately replace magnetic strip cards.
  • the present invention incorporates a buyer portable device having a value stored thereon and a buyer provider device, in electronic communication with the portable device.
  • the buyer portable device and the buyer provider device are configured to operate in conjunction to generate a view-only payment file and a payment file reflecting an adjustment to the value.
  • a buyer base device is in electrical communication with the buyer portable device and the buyer provider device and is configured to transmit the view-only payment file and the payment file across the network.
  • a seller base device is also in electrical communication with the network.
  • the invention may further include a seller portable device and seller provider device in electrical communication with the seller base device.
  • the seller base device is configured to receive the view-only payment file and the payment file from the network during a transaction.
  • the seller base device is further configured to transmit a view-only product file and a product file to the buyer base device.
  • a buyer accesses the network through the buyer base device.
  • the buyer may then review a seller's site which is hosted on a seller base device.
  • When the buyer may select one or more products on the site to purchase.
  • the products are capable of being embodied in a computer readable format and therefore may be electronically transmitted.
  • the buyer places the buyer portable device in electrical communication with the buyer base device.
  • the buyer base device deducts the purchase amount from the buyer portable device and relays the purchase amount to the buyer provider device.
  • the buyer provider device generates a payment file which constitutes payment and a view-only payment file which confirms the existence of the purchase amount file.
  • the buyer provider device encrypts the view-only payment file with a buyer system key.
  • the buyer provider device further encrypts the payment file with a buyer user key received from the buyer portable device and the buyer system key.
  • the view-only payment file and the payment file are simultaneously sent to the seller base device.
  • the seller base device sends the view-only payment file and the payment file to a seller provider device which is in electrical communication with the seller base device.
  • the seller base device retrieves the product and sends it to the seller provider device.
  • the seller provider device generates a view-only product file and a product file.
  • the product file contains the product and is encrypted with a seller user key and a seller system key.
  • the seller user key may be retrieved from a seller portable device in electrical communication with the seller base device.
  • the view-only product file confirms the existence of the product file and is encrypted with the seller system key.
  • the view-only product file and the product file are simultaneously sent to the buyer base device.
  • the buyer base device then sends the product file and the view- only product file to the buyer provider device.
  • the buyer provider device and the seller provider device decrypt the view- only product file and the view-only payment file respectively.
  • the buyer and seller are therefore able to confirm that the product file and the payment file are stored locally.
  • the buyer and seller user keys are exchanged to allow decryption of the product and payment files.
  • the buyer is then able to utilize the product.
  • the seller may add the value reflected by the payment file to a value stored on the seller portable device. In this manner transactions may be performed over a network, such as the Internet, that ensure that both parties receive their respective compensation.
  • Payment may be immediately taken from a buyer's account and subsequently added to a seller's account.
  • the product may be made immediately available to the buyer.
  • the provider devices act as an escrow agent to ensure that there is authorization before decrypting and releasing their respective product and payment files.
  • the invention may also be used with shipment of tangible products.
  • the seller base device and the seller provider device are manually carried by the shipping agent. If the product is accepted, the buyer portable device is placed in electrical communication with the seller base device. The buyer user key is then transmitted to the seller provider device. The seller provider device is then able to unlock the payment file. The payment file may then be transferred to a seller portable device in electrical communication with the seller provider device.
