Abstract

A method of and arrangement for updating inventory markings include printing an updated label containing updated information such as price obtained from the data base of a host computer on a real-time basis, The updated label is applied to a product identified by a scanner,

Claims

1. A method of labelling different products having different attributes with an integrated reader/printer unit, comprising the steps of:

(a) storing product identity information and data corresponding to the attributes of each product in a common data base of a host computer;

(b) situating a tag bearing coded indicia having parts of different light reflectivity adjacent to each of the products, each coded indicia representing the identity of a respective product;

(c) electro-optically scanning and reading the coded indicia on the tag situated with a product visually selected by a human operator by moving the unit relative to, and at a distance away from, the coded indicia to position thereon a light beam emitted exteriorly of the unit and movable across the coded indicia to automatically identify the product selected by the operator to the host computer on a real-time basis;

(d) accessing on a real-time basis the data base in response to the reading step to automatically retrieve the stored data corresponding to the attributes of the product selected;

(e) printing a bar code symbol representing the retrieved data on a label with the unit;

(f) applying the printed label to the product selected; and

(g) automatically reading the symbol on the printed label applied to the product selected to be automatically read at a point-of-transaction terminal to complete a commercial transaction.

2. The method according to claim 1, wherein the printing step is performed by also printing sequential coded data indicative of the total number of labels printed.

3. The method according to claim 1, wherein the data is a base price;

and further comprising the step of periodically changing the base price of a product whose price has changed and storing the changed price in the data base; and

wherein the printing step is performed by selectively printing the changed price on the label only if the base price of the product has been changed.

4. The method according to claim 1, wherein the reading, printing and applying steps are performed at a sales counter remote from the point-of-transaction terminal.

5. The method according to claim 1, wherein a surface of each product bears original indicia, and wherein the applying step is performed by applying the printed label over the original indicia so as to obscure the original indicia from being read, thereby updating the attributes of each product.

6. The method according to claim 1, wherein a surface of each product bears original indicia, and wherein the applying step is performed by applying the printed label adjacent the original indicia so that both the original indicia and the symbol on the printed label may be read.

7. An arrangement for expediting commercial transactions of products at a point-of-transaction terminal, comprising:

(a) a computer having a data base in which product identity information and data corresponding to attributes of each product are stored;

(b) a tag bearing coded indicia having parts of different light reflectivity situated adjacent to each of the products, each coded indicia representing the identity of a respective product;

(c) means for electro-optically scanning and reading the coded indicia on the tag situated with a product visually selected by a human operator, including means for directing a light beam exteriorly of the reading means, and means for movably positioning the light beam on the coded indicia on the tag of the selected product to automatically identify the selected product to the host computer and produce a signal when such identification is successfully made;

(d) means for accessing the data base on a real-time basis in automatic response to said signal from the reading means to retrieve the stored data corresponding to an attribute associated with each identified product;

(e) means for printing attribute information corresponding to the retrieved data on a label for each identified product on a real-time basis with the operation of the means for accessing the data base;

(f) adhesive means for adhering the printed label to each identified product; and

(g) means for completing a commercial transaction at the point-of-transaction terminal by electro-optically reading the attribute information on the printed label on a product presented to the point-of-transaction terminal.

8. The arrangement according to claim 7, wherein the data is a base price;

and further comprising means for periodically changing the base price of a product whose price has changed and storing the changed price in the data base; and

wherein the printing means selectively prints the changed price on the label only if the base price of the product has been changed.

9. The arrangement according to claim 7, wherein the reading, printing and applying means are located at a sales counter remote from the point-of-transaction terminal.

10. The arrangement according to claim 7;

and further comprising receipt means for printing a receipt evidencing the commercial transaction.

11. The arrangement according to claim 10, wherein the receipt means includes a printhead for imprinting graphical markings on a paper roll.

12. The arrangement according to claim 11, wherein the printhead has a tear-off edge.

13. The arrangement according to claim 11, wherein the printhead is connected to a portable data terminal.

14. The arrangement according to claim 13, wherein the terminal has a keyboard and a display.

15. The arrangement according to claim 11, wherein the printhead is connected to the scanning means.
