ABSTRACT:
In a transaction terminal system including a central computer and a number of remote intelligent terminals in intermittent communication with the central computer, the central computer periodically updates local hot card files at the terminals from a master hot card file. Hot card data stored at the central computer includes additional data indicative of the likelihood of a particular hot card being presented in a particular locality such that this additional data can be used to select subsets of hot card data for downloading to individual terminals, the subsets including data on hot cards deemed most likely to be presented in the locality of each terminal concerned.
