Point of sale terminal network implementation for transmitting data indicative of terminal changes upon switching of open close state of cash drawer
View Patent ↗Tracking at the local point of sale terminal level, changes in data associated with each terminal, such as a changed printer or POS register supporting a particular POS terminal, the identified cash drawer for the terminal, the particular changeable removable cash till in the cash drawer or the particular terminal operator. The POS terminal comprises a cash drawer including a drawer identifier, a cash till, including a till identifier, removably engagable with the drawer, as well as apparatus for reading the drawer identifier, apparatus for reading the till identifier when said till is engaged with the drawer and apparatus for transmitting the read drawer and till identifiers to the system administrator.
1. A point of sale network system including a plurality of point sale terminals connected to a system administrator, each of said terminals comprising:
a cash drawer including a drawer identifier;
a microprocessor incorporated into said cash drawer;
data indicative of changes related to each terminal stored in association with said microprocessor;
a device in each drawer, responsive to a switch in the open/close status of the drawer for transmitting the switch in status of said drawer to said system administrator via a status line; and
an implementation in said microprocessor, responsive to said switch in status, for transmitting said data indicative of changes to said system administrator via said status line.
2. The point of sale system of claim 1 wherein said switch indicates the opening of said drawer.
3. The point of sale system of claim 2 wherein said data indicative of changes is an identifier indicating a new till has been inserted into the drawer.
4. The point of sale system of claim 2 wherein said data indicative of changes is an identifier indicating chat the till of a new user has been inserted into the drawer.
5. The point of sale system of claim 3 wherein the stored data is a readable identifier on said new till.
6. The point of sale system of claim 4 wherein the stored data is a readable user identifier element inserted into the till.
7. The point of sale system of claim 2 wherein:
said plurality of terminals are a set of checkout lane terminals at a retail business;
said system administrator is a controller for correlating said transaction data received from said terminal with said drawer and said till identifiers;
each of said cash drawers has a fixed association with a corresponding terminal; and
each of said tills may be switched from cash drawer to cash drawer.
8. A method for transmitting data in a point of sale network system including a plurality of point sale terminals connected to a system administrator comprising:
storing a drawer identifier in association with a cash drawer in each terminal;
storing data indicative of changes related to each terminal stored in association with said cash drawer;
transmitting a switch in the open/close status of each drawer to said system administrator via a status line in response to said switch in status; and
also transmitting said stored data indicative of changes to said system administrator via said status line in response to said switch in status.
9. The method of claim 8 wherein said switch in status indicates the opening of said drawer.
10. The method of claim 9 wherein said data indicative of changes is an identifier indicating a new till has been inserted into the drawer.
11. The method of claim 9 wherein said data indicative of changes is an identifier indicating a new user associated with said drawer.
12. The method of claim 1 wherein:
said plurality of terminals are a set of checkout lane terminals at a retail business;
said system administrator is a controller for correlating said transaction data received from said terminal with said drawer and said till identifiers;
each of said cash drawers has a fixed association with a corresponding terminal; and
each of said tills is enabled to be switched from cash drawer to cash drawer.
13. A point of sale network system including a set of checkout line terminals at a retail business connected to a controller for correlating said transaction data received from said terminals, each of said terminals comprising:
a cash drawer having a fixed association with said terminal, and including a drawer identifier;
a cash till, including a till identifier of till user removably switchable between cash drawers;
apparatus for reading said drawer identifier;
apparatus for reading said till identifier during the engagement of said till with said drawer including:
an element for reading said till identifier of said user; and
a structure in said till adapted to receive said user identifier element in a position such that the user identifier is read by said apparatus for reading said till identifier during the engagement of said till with drawer;
apparatus for transmitting said read drawer and till identifiers to said controller;
a device for sensing the disengagement of said till; and
apparatus for signalling said controller that said till is disengaged from said drawer.
14. The point of sale system of claim 13 wherein said element for reading said till identifier is removably received in said till structure.
