Skyzer Technologies is currently undertaking a process of updating the software on our terminal
fleet to the latest 2018.1 (SHA-2) version 341 R1 Paymark software. This is for terminals that are
unable to dial in to our TMS and also includes iWL255 terminals with Paymark SIM cards. The USB
flash drives that have been issued will need to up update to the latest 2018.1 (SHA-2) version. This
will contain the Eftpos application that needs to be loaded into the terminals by following the
instructions below.
