DESCRIPTION:
BRIEF SUMMARY
This invention relates to a self-contained intelligent point of sale device
for the collection of sales data on presentation of valid identification card.
The object of the invention is to provide a data collection device which can be used to control and record the sales of commodities or services on a credit basis at the point of sale. It is a particular object to provide such a device which is suitable for controlling the sale of motor fuel and associated products using an identification card valid for one point of sale only.
Broadly the invention resides in a self-contained intelligent point of sale device for the collection of sales data on presentation of a valid identification card, said device comprising a microprocessor having a memory and a buffer, a keyboard for entering information concerning one or more transactions into the buffer, a recording unit interfaces with the microprocessor and a reader interfaced with the microprocessor for reading and checking the identification card against the memory whereby when the memory recognizes a valid identification card, the information concerning the transaction or transactions entered onto the buffer is transferred to and recorded in the recording unit together with particulars from the identification card.
Preferably the device also incorporates a display connected to the keyboard to display the entered information and/or signals generated by the microprocessor. The device may also include a printing unit for printing out a paper copy record setting out the entered information.
The invention will be better understood by reference to the following description of one specific embodiment as applied to the sale of motor fuel and associated products on a credit basis using identification cards supplied to individual customers. In this embodiment the use of the identification card is confined to a single sales point such as a service station.
In describing the embodiment reference will be made to the accompanying drawings wherein
FIG. 1 is a block diagram illustrating the system; and
FIG. 2 is a diagramatic representation of the keyboard.
The identification card issued to each customer is of conventional size and shape and has appropriate data recorded thereon in suitable form such as magnetic strip or embedded wires and includes a symbol which may be a number or combination of letters and numbers unique to that particular card. A card particularly suitable for the purposes of the present invention is that sold under the trade mark "Sensorcard" which has the appearance of a normal plastic credit card. It has wires embedded in the card representing that card's unique identifying symbol.
The microprocessor is of conventional design and is of sufficient capacity to recognize the valid and invalid card codes relative to the total number of customers of the service station and to perform all control functions required to drive a recording unit interfaces therewith, a printing unit for the production of hard or paper copy receipts and journal rolls as hereinafter described, a display, and a card reader. The microprocessor contains a memory of sufficient capacity to retail the following data: product
It also incorporates two buffers both of which are of sufficient capacity to retain the following data: transactions can be stored in the buffer at the same time)
The first buffer is known as a temporary transaction buffer while the second buffer is known as the write buffer, and both are used to temporarily hold data prior to transmission to data storage - for example to magnetic tape.
The system is powered by a power supply which will allow intermittent fluctuation in main voltage without rendering the system inoperative and which will maintain memory for a period of at least two months following withdrawal of main power.
The keyboard unit as shown in FIG. 2 which may be the mechanical or touch type comprises three separate banks of keys, the first bank comprises a numeric 0 to 9 keypad plus shift and clear keys, the second bank comprises a group of six keys control
