RFID Events

RFID events let you define what happens when a product is picked up or put back on the shelf. Beyond simple content switching, events can trigger playlists, display templates or activate additional actions.

Overview

An RFID event connects a trigger (tag detected or tag removed) to an action (display specific content, switch playlist or trigger an external action).

Event Types

Event	Trigger	Description
Tag Lifted	RFID tag moves away from the reader	Fires when a customer picks up a product.
Tag Placed	RFID tag returns to the reader area	Fires when a product is put back on the shelf.
Tag Changed	A different tag replaces the current one	Fires when a product is swapped for another one at the same reader position.

Create an RFID Event

Log in to the viewneo CMS at cms.viewneo.com.
Navigate to Devices → Smart Line → RFID Gateway.
Open the Events tab.
Click Add Event.

Configure the Trigger

Select the trigger type (Tag Lifted, Tag Placed or Tag Changed).
Select the tag ID or tag group that should trigger this event.
Optionally specify the reader if you have multiple readers and the event should only apply to a specific shelf zone.

Configure the Action

Define what should happen when the event fires:

Display Content – Show a specific slide, image, video or template on the player screen.
Switch Playlist – Switch the active playlist on the player to one assigned to the picked-up product.
Trigger URL – Send a request to an external URL (webhook) for integration with third-party systems.
Return to Default – Return to the default playlist or default content (typically used for “Tag Placed” events).

Assign a Player

Select the player or player group that should respond to this event.

Save

Click Save to activate the event. The event takes effect immediately.

Example: Product Information Display

A simple Lift & Learn setup:

Event 1 – Trigger: Tag Lifted (tag ID: A1B2C3D4). Action: Display content “Running shoe X - feature video”.
Event 2 – Trigger: Tag Placed (tag ID: A1B2C3D4). Action: Return to the default playlist.

The customer picks up the running shoe, sees a feature video, and when the shoe is put back, the screen returns to the general loop.

Example: Multi-Product Comparison

For installations with multiple products:

Create a “Tag Lifted” event for each product tag, each pointing to that product’s content.
Create a “Tag Changed” event that detects when a second product is picked up while another one is already off the shelf – this could trigger a comparison view.
Create a “Tag Placed” event that returns to the default content when all products are back on the shelf.

Manage Events

Edit an Event

Navigate to the Events tab under Devices → Smart Line → RFID Gateway.
Click the event you want to change.
Update the trigger, action or player assignment.
Click Save.

Delete an Event

Open the event details.
Click Delete Event.
Confirm the deletion.

Troubleshooting

Problem	Solution
Event does not fire when the tag is lifted	Check that the tag ID in the event matches the physical tag. Check reader detection in the Sensors section.
Wrong content is displayed	Check the content mapping for the tag ID. Make sure the correct media file or playlist is linked.
Event fires with a delay	Check the network latency between the RFID gateway and the player. Make sure the gateway firmware is up to date.
Multiple events fire unexpectedly	Check for overlapping tag or reader assignments. Make sure each tag ID is used in only one active event (unless intended).
