Payment Terminal & Retail Hardware worked example

Firmware Flashing Throughput at 99% flashing station uptime: a worked example in payment terminal & retail hardware

Push flashing station uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when firmware flashing throughput in payment terminal and retail hardware is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Terminals flashed per programming cycle: 4 units / cycle (unchanged)
  • Programming cycles available per shift: 480 cycles (unchanged)
  • Flashing station uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass flash-verify yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross firmware flashing throughput capacity = firmware flashing throughput output per cycle × available firmware flashing throughput cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good firmware flashing throughput capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross firmware flashing throughput capacity.
  • At this operating point the engine returns 19.2 units for firmware flashing throughput downtime loss.
  • At this operating point the engine returns 57.02 units for firmware flashing throughput yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where flashing station uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • It computes the number of good, verified terminals flashed per shift from output per cycle, available cycles, station uptime, and first-pass flash-verify yield. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Good firmware flashing throughput capacity: 1,844 units (headline result)
  • Gross firmware flashing throughput capacity: 1,920 units
  • Firmware flashing throughput downtime loss: 19.2 units
  • Firmware flashing throughput yield loss: 57.02 units
