Abstract: A wireless code symbol reading system including a wireless hand-supportable code symbol reader in two-way RF communication with a base station operably connected to a host system, by way of an RF-based wireless data communication link having a predetermined RF communication range over which two-way communication of data packets can occur. The wireless hand-supportable code symbol reader is programmed to automatically detect when it is located inside and outside of the predetermined RF communication range. When the wireless reader is inside the RF communication range, then symbol character data is automatically transmitted to the base station, and when the wireless reader is located outside of the RF communication range, then symbol character data is automatically collected and stored in a data packet buffer, until the wireless reader has re-entered its RF communication range.

Abstract: An automatically-activated code symbol reading system includes a hand-supportable housing having a light transmission aperture through which a field of view (FOV) passes; and an automatically-activated bar code symbol reading mechanism for repeatedly reading code symbols on an object in the FOV, within a predetermined time period, and in response to each new successful reading of the code symbols, producing a new symbol character data string representative of the read code symbol. A system control subsystem (i) automatically activates the automatically-activated bar code symbol reading mechanism in response to the detection of the object in at least a portion of the FOV, and (ii) automatically activates the data transmission circuit in response to the generation of the data transmission control activation signal so that a symbol character data string, produced currently with or immediately subsequent to the activation of the manually-activatable data transmission switch, is transmitted to a host system.

The transaction-enabling Internet terminal can be in the form of an Internet kiosk installed in a public location, in the manner as conventional ATMs. By virtue of the present invention, universal transaction machine (UTMs) can be easily deployed for use by the mass population so that they can easily conduct various types of transaction over the Internet.
