Definitions

  • the invention relates generally to performing fixed- value transactions with a smart card.
  • Smart cards also known as microprocessor cards or chip-cards, are plastic cards approximately the size of a credit card embedded with an integrated circuit (IC) chip.
  • IC integrated circuit
  • smart cards have become more attractive as the price of micro-computing power and storage have continued to drop. Furthermore, it has been recognized that the use of smart cards can help reduce the high overhead costs associated with transactions involving cash or credit cards.
  • Stored-value cards for example, lessen transaction costs by carrying monetary value directly instead of acting only as a pointer to an account.
  • Some smart cards, such as telephone-cards are designed to allow the purchase of products or services from a specific vendor and are used directly with the vendor' s equipment. Such smart cards provide a desirable marketing technique for the vendor and a convenient way for the consumer to gain access to the vendor's products or services .
  • the invention features a method of performing a fixed-value transaction using a smart card having stored therein initialization data including a count representing a specified number of fixed-value units.
  • the method includes generating a transaction message in the smart card and transmitting the transaction message to a vendor computer system.
  • the method further includes reducing the count stored in the smart card by a predetermined amount .
  • the transaction message can be transmitted over a computer network.
  • the initialization data can further include a predetermined number of fixed-value units required for each smart card transaction, and the method can include reducing the count stored in the smart card by the predetermined number of fixed-value units.
  • the method can include incrementing in the smart card a count indicative of a total number of transactions generated by the smart card.
  • the initialization data can further include an encryption key, and the transaction message can be encrypted with the encryption key.
  • the method can also include receiving the transaction message in the vendor computer system and decrypting the transaction message with a decryption key.
  • the transaction message can include a transaction identifier indicative of goods or services associated with the transaction.
  • the smart card can generate the transaction identifier based on parameters stored in the smart card as part of the initialization data.
  • the transaction message can further include the predetermined number of fixed-value units required for each transaction.
  • the transaction message can include a smart card identifier and a count indicative of a total number of transactions generated by the smart card.
  • the transaction message can be received in the vendor computer system which can verify that the predetermined number of fixed-value units corresponds to the transaction identifier. The count indicative of the total number of transactions for the smart card can also be verified.
  • the invention features a smart card including a memory storing a program and data representative of one or more fixed-value units and a microcontroller configured by the program to furnish the transaction and modify the data to reduce the number of fixed-value units by a predetermined amount when the transaction is furnished.
  • the smart card includes one or more of the following features.
  • the data stored in the memory can include a predetermined number of fixed-value units required for each smart card transaction, and the microcontroller can be configured by the program to modify and reduce the number of fixed-value units according to the predetermined number stored in the memory.
  • the data stored in the memory can include an encryption key
  • the microcontroller can be configured by the program to encrypt each transaction message generated by the smart card with the encryption key.
  • the microcontroller also can be configured by the program to include a transaction identifier as part of each transaction message generated by the smart card.
  • the microcontroller can be configured by the program to include the predetermined number of fixed-value units as part of each transaction message generated by the smart card.
  • a count, indicative of a total number of transactions generated by the smart card can be stored in the memory.
  • the microcontroller can also be configured by the program to increment the count by one each time a transaction message is generated by the smart card.
  • the microcontroller can be configured by the program to include, as part of the transaction message, the total number of transactions generated by the smart card.
  • a multi-parameter algorithm can be permanently stored in the memory and vendor-specific parameters can be stored in the memory.
  • the microcontroller can be configured by the program to include a transaction identifier, based on the multi-parameter algorithm and the vendor-specific parameters, as part of each transaction message generated by the smart card.
  • the invention provides one or more of the following advantages. Various implementations of the invention provide a convenient, robust and tamper-proof technique for the marketing and sale of access to a particular vendor's goods or services. Furthermore, the invention provides for secure, non- reputable transactions without the need for using third parties to facilitate or implement the transfer of goods or services. Moreover, the transactions can occur with relatively small transaction costs. Minimizing transaction costs is particularly important with respect to micro- transactions, in which the cost of the goods or services is of the same order of magnitude as the transaction costs.
  • various implementations of the invention allow a smart card holder to initiate a secure transaction for goods or services without requiring the smart card to interact directly with the vendor's equipment.
  • the smart card need not be read by a smart card reader/writer attached to the vendor's equipment.
  • the smart card can be used to initiate a transaction over a general-purpose computer network.
  • the smart card since the smart card is intended for fixed-value transactions with a specific vendor, only a single communication from the card to the vendor's system is needed to conclude the transaction.
  • the smart card provides all the information required, including an indication of the goods or services, as well as the cost.
  • the vendor's system receives all the information needed to conclude the transaction without having to transmit any information or instructions to the smart card.
  • the vendor's system need not instruct the smart card to reduce the number of stored monetary units on the card according to the cost of the goods or services. Since the cost of the goods or services in fixed in advance, the smart card itself automatically performs this function.
  • the invention is particularly advantageous, for example, in the context of obtaining services for which a consumer would otherwise have to pay a high subscription price.
  • a consumer may desire access to a vendor's on-line services available over the Internet, but expect to access the on-line services only a limited number of times.
  • the consumer does not wish to pay the full subscription price which the vendor would otherwise charge.
  • the invention facilitates such a transaction by allowing the consumer to purchase the opportunity to access the on-line services a limited number of times through the use of the smart card. Once the services have been accessed the predetermined number of times, the card holder can no longer access the vendor's on-line services.
  • the invention has applications to transactions involving other goods and services as well .
  • FIG. 1 is an exemplary system in which the invention can be practiced.
  • FIG. 2 shows initialization data stored on a smart card according to the invention.
