ExitView loss prevention RFID simulator
Put a row of ExitView pedestals across a store exit and walk a person out with clothes, shoes or cosmetics, or along the row inside the store without leaving. Compare the pedestals working alone with the Identix IRIS SLP solution: alarms, false alarms and which pedestals sound.

What this simulator calculates
It compares, at a store exit with a row of ExitView pedestals, the pedestals working alone (each with its EM300 reader) and the Identix IRIS SLP solution (in development): how often a person leaving with unpaid clothes, shoes or cosmetics raises an alarm, which pedestals sound, and how often someone walking by inside the store raises a false alarm.
What you can set
- The row: 2 to 8 pedestals and the free gap between them (1.0 to 2.0 m; 1.30 to 1.50 m is usual).
- What the person does: crosses one lane leaving the store, or walks along the row inside the store at a chosen distance without crossing.
- The goods (clothes, footwear or cosmetics), how they are carried (bag, backpack, garments over the arm or cart), the power of each antenna port and a rack standing near the exit.
What you see
- The tags a typical pass reads, and the read failures as a count of tags over the simulated passes.
- The same setup with Impinj Gen2X on and off, side by side.
- A 3D view of the pass: the lobe of each antenna, the zone where a tag is read in at least 90% of the tries, and the chance of a read per tag.
- Notes on the setup, such as the EIRP of each antenna against the local limit you type in.
- Stray reads: how often goods that must not be read (beside the reader, the next load, a neighbour) are read, with an alert and how to reduce them.
Questions about the simulator
Is the simulator free? Do I need to install anything?
It is free and runs in the browser, with no sign-up and nothing to install. It needs JavaScript and a browser with WebGL for the 3D view.
Does the result replace a test on site?
No. It is an estimate from a propagation model, the antenna patterns and premises from the literature. Use it to compare setups and prepare the project, then confirm with a pilot on site, with the real tags and products. Identix can help you plan that test.
Who is it for?
For system integrators, meaning any company that builds its own solution, in full or in part: software companies that use Identix readers, makers of their own portals or reading cabinets who buy only antennas or readers, and also installers and end users who are planning a project.
Why do people walking inside the store set off alarms?
A pedestal working alone sounds for any unpaid item it reads, and its antennas also reach the store side of the row. The IRIS SLP solution coordinates the pedestals as one point of exit and gives an event only when the two pedestals of a lane see the item pass; the page shows both side by side.
What is a stray read and how do I reduce it?
An alarm for goods that did not leave: a person walking by inside the store, or the garments on a rack near the exit. Turn on the rack near the exit or the walk in front of the row in the simulator to see how often it happens. More distance between the row and racks or walkways, a lower power and the IRIS SLP solution, which asks both pedestals of a lane to see the item pass, reduce it.
