  • a terminal comprises a processor and a memory in which necessary software is stored. When the user selects a function, the software is read in the memory and executed.
  • Terminal design involves an inevitable compromise between the number of functions and the memory capacity available. For reasons of cost, the size of the memory to be placed in the terminals cannot be limitlessly increased; the number of functions is thus restricted by the memory.
  • examine a pay phone system implemented by means of a radio system The system comprises a number of pay phones, each being connected to base stations via a radio path. As far as the radio path and the base stations are concerned, terminals operating as pay phones do not differ from common terminal equipment in any way.

  • a charging means can typically be a reader for a pay card.
  • Various pay cards abound, including different credit cards, loadable pay cards and bank cards.
