1. A method of forming a bar code, comprising:
- forming a first bar code portion, which represents a first format bar code, and would be found as valid when scanned by a first bar code scanning process, said forming using first information to form the bar code portion, andforming a second bar code portion separate from but associated with the first bar code portion, formed in a second format which is different than said first format, and said forming forms said second bar code portion associated with said first format bar code portion, and forming said second bar code portion using second information comprising the same information as said first information that is found in said first bar code portion, and additional information that is different than said first information, wherein said forming said first bar code portion and said second bar code portion forms said first and second bar code portions integrated together into a single bar code formed by machine on a substrate,wherein said first information includes an address used to access a remote database that stores information, and wherein said second information includes information that is also stored in said remote database that is accessed by said first information, and wherein said second information is in a color of the bar code, whereby scanning with a monochrome scanner returns only said first information which can be used for accessing said remote database, and scanning said color information provides the actual information that would have been obtained from accessing the database using said first information.

1. A method of forming a bar code, comprising:
-
forming a first bar code portion, which represents a first format bar code, and would be found as valid when scanned by a first bar code scanning process, said forming using first information to form the bar code portion, and forming a second bar code portion separate from but associated with the first bar code portion, formed in a second format which is different than said first format, and said forming forms said second bar code portion associated with said first format bar code portion, and forming said second bar code portion using second information comprising the same information as said first information that is found in said first bar code portion, and additional information that is different than said first information, wherein said forming said first bar code portion and said second bar code portion forms said first and second bar code portions integrated together into a single bar code formed by machine on a substrate, wherein said first information includes an address used to access a remote database that stores information, and wherein said second information includes information that is also stored in said remote database that is accessed by said first information, and wherein said second information is in a color of the bar code, whereby scanning with a monochrome scanner returns only said first information which can be used for accessing said remote database, and scanning said color information provides the actual information that would have been obtained from accessing the database using said first information. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A method of scanning a bar code, comprising:
-
using a machine for scanning a first barcode part to obtain only first information; using a computer for interpreting said first information including an address of a remote database; accessing said remote database using said address to obtain first additional information; using a machine for scanning a barcode second part that is integrated with said first barcode part to obtain second information from a color of the barcode second part; wherein said barcode second part is formed in a second format which is different than a first format of said first barcode part; interpreting said second barcode part to obtain second information, where said second information includes the same information as said first information, and at least second additional information beyond said first information, and where said first additional information obtained from accessing said database using said address obtains information that is also stored in said second information obtained from interpreting said second barcode part, wherein scanning with a monochrome scanner returns only said first information which can be used for accessing said remote database, and scanning said color information provides the actual information that would have been obtained from the database. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of using a barcode comprising:
-
using a computer for encoding a first part of the barcode to have first information encoded therein in a first bar code format; said first information including an address of an internet-accessible database; storing second information in said internet accessible database; and encoding a second part of the barcode which is integrated with said first bar code format together into a single bar code to form said second part of said barcode in a second format which is different than said first format and to have said second information, where said second information includes the same information as said first information, and at least second additional information beyond said first information encoded therein, and wherein said second information is encoded in a color of the barcode, said encoding carried out such that scanning said first part of said barcode with a monochrome scanner returns only said first information which can be used for accessing said Internet accessible database, and said second information from the color of the barcode provides the actual information that would have been obtained from the Internet accessible database. - View Dependent Claims (17, 18, 19, 20, 21)
