Abstract

A method of conducting computerized commerce on a number of computer systems connected by a computer network including providing a broker computer system, the broker system having a database of broker scrips, each of the broker scrips representing a form of electronic currency, providing a vendor computer system, the vendor computer system having a database containing products which may be exchanged for the broker scrips, the vendor computer system capable of providing vendor scrips, providing a consumer computer system, the consumer computer system having a user interface wherein a user may initiate transactions in the consumer computer system to obtain one or more of the products contained in the database of the vendor computer system, sending a first request from the user on the consumer computer system to obtain a first broker scrip from the broker computer system, processing the first request in the broker computer system, sending the first broker scrip to the consumer computer system in response to the step of processing, sending a second request from the broker computer system to obtain a first vendor scrip from the vendor broker computer system, processing the second request in the vendor computer system, sending the first vendor scrip to the broker computer system in response to the step of processing the second request, sending a third request from the consumer computer system to the broker computer system for a first product, exchanging the first broker scrip for the first vendor scrip, and delivering the product to the consumer computer system in response to the step of exchanging.

generating a plurality of broker scrips in a broker computer system;

purchasing a first of the generated broker scrips from the broker computer system, the first broker scrip being transmitted to a consumer computer system;

receiving the first broker scrip in the broker computer system from the consumer computer system;

validating the first broker scrip in the broker computer system;

exchanging a first of the vendor scrips received in the broker computer system for the validated first broker scrip;

transmitting the first vendor scrip to the vendor computer system;

validating the first vendor scrip; and

transmitting a product to the consumer.

2. The method of conducting computerized commerce according to claim 1 wherein each of the plurality of scrips is encoded and includes:

a broker/vendor code field;

a scrip value field;

an expiration date field;

a serial number field;

a verification code field;

a valid flag field; and

a category field.

3. The method of conducting computerized commerce according to claim 2 wherein the step of purchasing the first broker scrip from the broker computer system comprises the step of exchanging currency for the first broker scrip, the currency selected from any one of:

credit card; and

computerized virtual cash equivalents.

4. The method of conducting computerized commerce according to claim 1 wherein the step of validating the first broker scrip comprises the steps of:

verifying that the first broker scrip has a correct number of data fields;

verifying that the first broker scrip is unspent;

verifying that the first broker scrip is signed;

verifying that the first broker scrip has sufficient value for the product;

verifying that a user credential is adequate; and

signaling a result of the validation.

5. The method of conducting computerized commerce according to claim 4 wherein the step of signaling comprises the steps of:

marking the scrip serial number as spent in the broker computer system if the validation is successful; and

sending an error message if the validation is unsuccessful.

6. The method of conducting computerized commerce according to claim 1 wherein the step of validating the first vendor scrip comprises the steps of:

verifying that the first vendor scrip has a correct number of data fields;

verifying that the first vendor scrip is unspent;

verifying that the first vendor scrip is signed;

verifying that the first vendor scrip has sufficient value for the product;

verifying that a user credential is adequate; and

signaling a result of the validation.

7. The method of conducting computerized commerce according to claim 6 wherein the step of signaling comprises the steps of;

marking the scrip serial number as spent in the vendor computer system if the validation is successful; and

sending an error message if the validation is unsuccessful.

8. The method of conducting computerized commerce according to claim 1, wherein the broker computer system further includes the capability of generating a vendor scrip.

21. A method according to claim 1, wherein exchanging the first vendor scrip for the validated first broker scrip includes transmitting a second of the generated broker scrips to the consumer computer system.

9. A method of conducting computerized commerce on a plurality of computer systems connected by a computer network comprising the steps of:

sending a first request from a consumer computer system to obtain a first broker scrip, representing electronic currency, from a broker computer system;

processing the first request in the broker computer system;

sending the first broker scrip to the consumer computer system in response to the processing;

sending a second request from the broker computer system to obtain a first vendor scrip from a vendor computer system;

processing the second request in the vendor computer system;

sending the first vendor scrip to the broker computer system in response to the processing of the second request;

sending a third request from the consumer computer system to the broker computer system for a first product;

exchanging the first broker scrip for the first vendor scrip; and

delivering the product to the consumer computer system in response to the exchanging.

10. The method of conducting computerized commerce according to claim 9 wherein each of the broker and vendor scrips are encoded and include:

a broker/vendor code field;

a scrip value field;

an expiration date field;

a serial number field;

a verification code field;

a valid flag field; and

a category field.

11. The method of conducting computerized commerce according to claim 9 wherein the step of processing the first request comprises the steps of:

validating authenticity of a user;

receiving a currency from the user;

validating the currency of the user;

generating the first broker scrip, the first broker scrip having an appropriate broker/vendor code field, a scrip value field, an expiration date field, a serial number field, a verification code field, a valid flag field, and a category field; and

encoding the first broker scrip.

12. The method of conducting computerized commerce according to claim 9 wherein the step of processing the second request comprises the steps of:

validating authenticity of the broker computer system;

receiving a currency from the broker computer system;

validating the currency of the broker computer system;

generating the first vendor scrip, the first vendor scrip having an appropriate broker/vendor code field, a scrip value field, an expiration date field, a serial number field, a verification code field, a valid flag field, and a category field; and

encoding the first vendor scrip.

13. The method of conducting computerized commerce according to claim 9 wherein the exchanging of the first broker scrip for the first vendor scrip comprises the steps of:
