Abstract
Wireless data communications using a master/slave protocol are easily established between a master radio module which is part of a POS terminal and a slave radio module which is part of a portable bar code scanning device. A bar code identifying the portable bar code scanning device is provided on the outside of the housing of the portable device. By scanning this bar code with a scanner associated with the POS terminal, such as a fixed scanner built onto a counter, the master/slave radio communications link can be automatically implemented.
