RFID Events

RFID Events allow you to define what happens when a product is picked up or placed 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 zone	Fires when a product is placed back on the shelf.
Tag Changed	A different tag replaces the current one	Fires when one product is swapped for another on the same reader position.

Creating an RFID Event

1. Log in to the viewneo CMS at cms.viewneo.com.
2. Navigate to the RFID Plugin section.
3. Open the Events tab.
4. Click Add Event.

Configure the Trigger

1. Select the trigger type (Tag Lifted, Tag Placed, or Tag Changed).
2. Select the tag ID or tag group that should trigger this event.
3. Optionally, specify the reader if you have multiple readers and want the event to apply only 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 — Change the active playlist on the player to one associated with the lifted product.
• Trigger URL — Send a request to an external URL (webhook) for integration with third-party systems.
• Return to Default — Revert to the default playlist or content (typically used for “Tag Placed” events).

Assign to 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 basic Lift & Learn setup:

1. Event 1 — Trigger: Tag Lifted (Tag ID: A1B2C3D4). Action: Display Content “Running Shoe X - Features Video”.
2. Event 2 — Trigger: Tag Placed (Tag ID: A1B2C3D4). Action: Return to Default playlist.

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

Example: Multi-Product Comparison

For installations with multiple products:

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

Note

Multi-product comparison events require careful planning of the trigger logic. Test thoroughly with your specific product set before deploying.

Managing Events

Editing an Event

1. Navigate to the Events tab in the RFID Plugin.
2. Click on the event you want to modify.
3. Update the trigger, action, or player assignment.
4. Click Save.

Deleting an Event

1. Open the event details.
2. Click Delete Event.
3. Confirm the deletion.

Caution

Deleting an event is permanent. Consider whether you need the event configuration before removing it.

Troubleshooting

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

• RFID Tags — Review tag assignments and content mapping.
