V-Link Overview

V-Link is the method used to create interfaced EFTPOS solutions using VeriFone terminals. V-Link supports 3 different protocols that may be used to communicate with the EFTPOS terminal.

  • VX-Link: This is a full featured protocol that supports POS printing;
  • VL-Link: This is a simple protocol designed for simple POS applications and ECRs;
  • Gen-Link: This is not strictly a single protocol but Gen-Link is able to interpret legacy one-way protocols;

The choice of protocol will depend on your specific requirements. If your POS application already supports a simple legacy POS integration protocol then it is possible that no development work is required and you can progress straight to testing the solution. Please contact Sektor for the legacy protocols that are supported. If you do not support a legacy protocol or you wish to support a protocol with more features then the VX-Link protocol will probably be the best choice. It has the most features and a solution using VX-Link can easily be upgraded to use Vault (an integrated solution) at a later stage. The table below describes the features of the various protocols.
