Abstract

A pocket size data terminal is described for use by a large number of consumers in a system with which goods or services can be conveniently and automatically ordered. A plurality of data terminals which can automatically dial a local processing center (LPC) are distributed among users each of whom can address the LPC with a unique user identification and an internal terminal identification. The terminal is internally battery powered. Each data terminal can accumulate orders for goods or services in a send memory while the terminal is unencumbered by any external connector. When subsequently connected to a phone line modular jack, upon command by a user send memory contents are automatically sent to an LPC in a short burst. The LPC verifies the use of the terminal, the authorization of the requested service and format of the data as well as other items as may be included in the order. Upon verification, the LPC returns an appropriate message for visual display at the terminal and processes the order to suppliers of the requested goods or services.

means for terminating said telephone link a predetermined short time after said evaluation response transmittal to limit the duration of said communication link.

2. The system as claimed in claim (2) 1 wherein said data terminal further includes:

means for identifying an order as one to be cancelled by the local processor center.

3. The system as claimed in claim 2 wherein said data terminal further includes:

means for effectively locking out the keyboard when order data has been identified as to be cancelled.

4. The system as claimed in claim 2 wherein the data terminal further includes:

means for effectively locking out the keyboard for the time when the communication link is established.

5. The system as claimed in claim 4 wherein the data terminal further includes:

means for identifying an order as a practice order.

6. The system as claimed in claim 4 wherein the verifying means further includes:

means for storing at the local processor center the data terminal identification in association with a known authorized user identification;

means for comparing the user identification received from the data terminal with the user identification initially stored in the local processor center and authorized with the data terminal identification;

means for limiting service by the local processor center to a data terminal after a predetermined number of attempts by said comparing means have failed.

7. The system as claimed in claim 1 wherein the local processor center further includes:

means for identifying an emergency order from the order data sent by the data terminal and generating a signal indicative thereof.

8. The system as claimed in claim 1 wherein the local processor center further includes:

means for identifying order data from a data terminal as signifying a request for a cable television program; and

means responsive thereto for generating signals to enable the user of the data terminal to receive said cable television program.

9. The system as claimed in claim 1 wherein the local processor center further includes:

means for identifying order data from a data terminal as signifying an address change;

means for transmitting to said data terminal data representative of a phone number associated with the address change;

and wherein the data terminal further includes means for replacing the phone number associated with the local processing center with the phone number associated with the address change.

10. A data terminal to enable a plurality of users to place requests with a central processor through telephone lines with a plurality of such data terminals located at user locations comprising:
