Abstract

A point of sale terminal is disclosed that provides all of the usual point of sale terminal functions, but that is entirely field portable. Data pertinent to each purchase can be input to the terminal via a keyboard assembly, a touch-screen display or a signature-capture screen assembly, or via an antenna and radio link from an associated bar code scanner. Data may be communicated at any time to a remote host computer, also via a separate antenna and radio link. The communication links with the host computer and the bar code scanner operate independently and simultaneously, using mutually compatible modulation schemes such as a spread spectrum scheme for the host computer link and a narrowband or spread spectrum scheme for the bar code scanner link. The terminal thereby functions as a portable repeater or node in a data communications network.

Claims

1. A portable point of sale terminal comprising:

a hand-carryable housing having a front face;

a power source located within the housing;

a keyboard and display mounted on the front face of the housing;

a screen mounted on the front face of the housing, for sensing the manual writing of information thereon and generating corresponding data; and

a printer located within the housing, for printing information on a strip of paper and discharging the printed paper from the housing;

wherein the printer is located adjacent to the screen and is arranged such that the discharged paper overlays the screen.

2. A portable point of sale terminal as defined in claim 1, wherein:

the front face of the housing includes means defining a slot sized to receive one edge of plastic credit card; and

the point of sale terminal further includes a magnetic card reader located adjacent to the slot in the front face of the housing, for reading information stored in a magnetic strip carried on a plastic credit card slid along the slot.
