Abstract

Bar codes used for various applications. A bar code can be used for biometrics, or for computer data entry. A special bar code is described that has additional information, but can be read by other readers.

said using including first reading said first barcode part to obtain a first item of information from said first reading;

said using including second reading said second barcode part to obtain a second item of information that is different than said first item of information;

using the overall information part formed having said concatenated information, by said barcode reader device, as representative of the barcode reading,

wherein said first barcode part represents data that is used to access a remote database, where said data from said first barcode part is used to address detailed information in the database,

where said data from said first barcode part that is used to access the remote database is not a website address,

and further comprising using said data from said first barcode part to access the remote database and to receive back the same information as is contained in said concatenated information, and

checking said first reading using a checking function operating on the computer, that determines if said reading is valid, and operating said first reading and said second reading only if said checking determines that the reading is valid.

10. A method as in claim 9, wherein said first barcode part is a one-dimensional barcode and said second barcode part is a two-dimensional barcode.

11. A method as in claim 9, wherein said barcode reader device includes a hand-held computer based device which includes a display screen.

12. A method as in claim 11, further comprising sending said concatenated information from said handheld computer based device to a remote database.

13. A method as in claim 12, further comprising receiving information from the remote database, and displaying said information that is received on the display screen of the device.

14. A barcode reading system, comprising:

a hand-held barcode reading device which includes a display screen, said hand-held barcode reading device operative to read a barcode, said hand-held barcode reading device having a computer therein which is programmed for checking plural items of information within a barcode area within said barcode using a checking function running on said computer in said barcode reading device, wherein said computer is programmed for checking multiple parts in said barcode including a first barcode part and a second barcode part using a checking function, wherein said first barcode part encodes a first set of information including plural different items of information, and said second barcode part encodes a second set of information including plural different items of information, wherein at least one of said plural different items of information within said first set of information represents the same information as at least one of said items of information within said second set of information, and where said second set of information also includes additional items of information beyond that in said first set of information,

said computer operating to use said checking function to determine whether information that was obtained by reading said second barcode part represents valid information,
