Abstract

A mobile customer service station includes a console on a wheeled chassis. The console carries and houses a number of components which are used in merchandising operations to conclude customer purchase transactions. The items supported externally on the console are a printer for printing purchase receipts, customer credit charge agreements and records of transactions, and a magnetic card reader for reading information from a magnetic stripe of a customer'"'"'s credit card. The console further features a cash drawer. The operation of the printer, credit card reader and the cash drawer is controlled by a multifunction control unit located within an enclosure of the console. The control unit is electrically powered by a self-contained power source which is preferably a deep cycle rechargeable battery. The console also houses a transceiver unit which under the control of the control unit is capable of interactive communication with a radio communications system. The radio communications system is controlled by a central computer and includes a plurality of portable data terminals which are coded to individually communicate with the central computer. The infusion of the customer service station into the radio communications system allows the data terminals to become data entry units for the mobile customer service station. The self-contained power source and the transceiver permit the customer service station to be moved to merchandising locations of temporary peak customer activity without the expense or time requirements of first having to install electrical services.

Claims

1. A transaction control system comprising:

(a) at least one portable data terminal, said data terminal including means for entering data relating to customer transactions and means for transmitting uniquely identifiable data messages based on the entered data;

(b) at least one mobile customer service station, said service station including a self-contained power source, a printer for printing customer transaction records and means for receiving customer transaction-related messages pertaining to customer transactions which originate at the portable data terminal;

(c) wireless communications station means including means for receiving said uniquely identifiable data messages transmitted from said portable data terminal, and for transmitting to said portable data terminal and to said mobile customer service station customer transaction-related data messages pertaining to customer transactions which originate at said portable data terminal; and

(d) computer means, said computer means being communicatively interconnected with said wireless communications station means for transfer of said uniquely identifiable data messages from said wireless communications station means to said computer means, means for receiving from said wireless communications station means said uniquely identifiable data messages which originate at said portable data terminal, means for processing said uniquely identifiable data messages and generating customer transaction-related data messages pertaining thereto, means for uniquely addressing such customer transaction-related data messages to a selected one of said portable data terminal and said mobile customer service station, and means for transferring said customer transaction-related data messages to said wireless communications station means,

(e) said mobile customer service station upon receipt of said customer transaction-related data messages from the wireless communications station means being controllable to cause said printer to print customer transaction records in accordance therewith.

2. A transaction control system according to claim 1,

wherein said portable data terminal comprises a transceiver including coding, decoding, transmitting, and receiving circuits, and wherein said coding and transmitting circuits of said portable data terminal transceiver are included in said means for transmitting uniquely identifiable data messages, and

wherein said mobile customer service station comprises a transceiver including coding, decoding, transmitting, and receiving circuits, and wherein said coding and transmitting circuits of said mobile customer service station transceiver are included in said means for receiving customer transaction-related data messages.

3. A transaction control system according to claim 2, wherein said at least one portable data terminal is a first plurality of portable data terminals, and wherein the number of said portable data terminals in said first plurality of portable data terminals is greater than the number of said at least one mobile customer service station.

4. A transaction control system according to claim 2, wherein said at least one portable data terminal is a first plurality of data terminals, and wherein a ratio of the number of such portable data terminals in such first plurality of data terminals to the number of said at least one mobile customer service station is a ratio of at least two to one.

5. A transaction control system according to claim 2, wherein said at least one mobile customer service station further includes a control unit, said control unit including said coding and decoding circuits of said mobile customer service station transceiver, said control unit further including a first communications connector and means for coupling said coding and decoding circuits to said communications connector, and wherein said transmitting and receiving circuits of said mobile customer service station are mounted in a housing, said housing including a connector matched to interconnect with the first communications connector of said control unit, and means for coupling said transmitting and receiving circuits of said mobile customer service station to said housing connector, such that upon interconnection of said housing and communications connectors, said coding and decoding circuits of said mobile customer service station and said transmitting and receiving circuits of said mobile customer service station are communicatively interconnected.

6. A transaction control systems according to claim 2, wherein said at least one mobile customer service station further comprises:

a magnetic card reader for reading data from a customer'"'"'s credit card; and

a control unit communicatively coupled to the printer, the magnetic card reader, and the transceiver in said mobile customer service station, said control unit including means for controlling the operation of the printer, the magnetic card reader and the transceiver in said mobile customer service station, means for receiving data from the magnetic card reader and for receiving data messages from the transceiver in said mobile customer service station, and means for transferring data messages according to data received from the magnetic card reader to the transceiver in said mobile customer service station for transmission to said computer means via said wireless communications station means.

7. A transaction control system according to claim 6, wherein said at least one mobile customer service station further comprises:

a cash drawer, said said drawer including an operating circuit operable to open said cash drawer upon receipt of a cash drawer control signal, said operating circuit being communicatively coupled to said control unit, and

means included within said control unit, for sending a cash drawer control signal to said operating circuit of said cash drawer.

8. A transaction control system according to claim 7, wherein said at least one mobile customer service station further comprises:

a digital display, means for receiving and storing digital data and messages for display;

a data input device coupled to said display for acquiring data in digital format for transfer to said display; and

means for communicatively coupling said display to said control unit for transferring data between said display and said control unit, such transfer permitting coding of data transferred from such display and transmission of such coded data to said computer.

9. A transaction control system according to claim 8, wherein said data input device is a keyboard having a plurality of alphanumeric input keys for entering data into said display, and including a prompt for causing the transfer of such entered data to said control unit.
