Registration without an action. Even when it is busy.
A scan happens when someone does it. On a busy day scans get skipped, and it is exactly that shipment someone asks about later. A gate records what passes without anyone being involved, so the gaps in your registration disappear.
At a dock, a doorway or between two zones. Where it ends up standing is the biggest choice.

What to look at when choosing
With a gate the technology is rarely the problem. The placement is.
- What passes
- A pallet, a roll cage, a person with a box: that sets the height and width
- How fast
- Walking pace or a forklift at speed. That sets the read window
- What stands next to it
- Racking right beside the gate gets read along unless you do something about it
- Direction
- Only registering that something passes, or also whether it goes in or out
What a gate does and what it does not do
Wel
- Record what passes, without anyone doing anything
- Read hundreds of tags at once, even on a full pallet
- Determine direction, so inbound and outbound stay apart
- Run without supervision, day in day out
Niet
- Shield what stands next to the gate: that is what a Faraday cage is for
- Read what does not come through the gate
- Guarantee that a tag deep inside a pallet with metal is seen
- Determine what is inside a box, unless that content is labeled itself
The difference between a gate and a Faraday cage is exactly this: a gate sees everything within range, including the racking next to it. At a dock in an open hall that is no problem; in the middle of a warehouse it is. So where the gate ends up standing is something we settle in the Proof of Value and not on a floor plan.
