Navigation systems

These devices use a GPS (also known as Global Positioning Satellite) receiver to locate the user’s position on a digital map and provide directions to a given destination.


This can be an example of an in-car satnav which uses GPS location data with software to provide directions to given destination when driving.

Data capture and collection systems

These devices collect and input data through automated systems rather than direct data entry.


There are examples of the uses of data capture and collection systems.

  • An barcode scanner; which inputs a barcode and converts the information in to data.
  • An optical mark reader; which reads pencil or pen marks on specially designed printed forms, such as lottery tickets and exam papers.
  • An EPOS (which stands for Electronic Point of Sale) system, which records sales and updates stock levels.
