Abstract
A hand-held scanner incorporates a cellular telephone module. The scanner communicates with a host which serves as a reading or data distribution device. This permits the use of a cableless scanner for low powered and secure wireless transmission. The scanner is able to take advantage of the existing design features of a local cellular network. One mode of operation allows the connection to be limited to an amount of time corresponding to that required for transferring of the data.
