Patent ID: 7240360

Claim:
A computer-implemented method for controlling access to user interface fields in a point-of-sale system having a plurality of different user interface fields, the method comprising the steps of: operating the point-of-sale system in a security setup mode of operation by: accessing the plurality of user interface fields, wherein some of the user interface fields include a set of modifiable access properties that indicate a level of access needed to access that user interface field; establishing an access profile for each user of the point-of-sale system, the access profile indicates the level of access of user interface fields that each user is allowed to access; and controlling a value in each user interface field displayed on the point-of-sale system during a normal mode of operation by comparing the level of access indicated in the access profile of a user of the point-of-sale system with the level of access of each user interface field, wherein only those values in the user interface fields that have access property levels equal to or less than the level of access indicated in the access profile of the user are displayed.
