Often the reader used with a terminal has significant bearings on the success and cost of the overall solution provided. All Isys hardware can be adapted to utilise any of the following: Proximity, Magstripe, Bar Code, Pin-Code or Biometric readers.

Below is a basic overview of each technology and a + and – breakdown.  The below pros and cons should provided the reader with a good understanding of the cost, security, readers and reliability issues with the different technology.

Proximity cards or fobs (iClass, Mifare or bespoke formats) offer the quickest and most user friendly (no alignment sensitivity) read interface, which can also provide other functions like door access, cashless vending etc.

Barcode cards offer the optical immunity from any form of interference, occasionally required when manufacturing heavy plant, or in research facilities. This format also allows integration with other existing barcode readers and systems found in the workplace.

Biometrics provide the greatest protection against fraudulent clocking, or eliminate the need to carry cards or fobs in areas not permitted, such as food processing.
