POS Integration for Digital Signage
Quick answer: DigitalSignage.com's guidance for POS-driven menu boards: connect the point-of-sale system to the signage CMS by direct API (Square Catalog API, Toast Menu API, Clover REST API, Lightspeed, Revel, TouchBistro), through no-code middleware such as Zapier or Make.com, through a shared database on premises, or by scheduled CSV or XML export for POS systems without an API. With webhooks, a price change in the POS reaches the screens within seconds; polling every few minutes is the fallback. Sync prices and availability in real time, menu structure hourly or daily, and let 86'd items hide themselves or show Sold Out automatically so staff never edit menu boards by hand.
Integrating your point-of-sale (POS) system with digital signage enables automated menu updates, dynamic pricing, inventory-based messaging, and seamless operational efficiency. This guide covers integration approaches for major POS platforms.

Frequently asked questions
How do I connect my POS system to digital menu boards?
Most modern POS systems offer APIs that can connect to digital signage CMS platforms. The integration typically involves: obtaining API credentials from your POS provider, configuring your signage CMS to pull data from the POS API, creating templates that display POS data dynamically, and setting up sync schedules. Popular POS systems like Square, Toast, and Clover all offer integration options.
Can digital signage automatically update when I change prices in my POS?
Yes, with proper POS integration, price changes in your POS system can automatically update digital signage within seconds. This requires either webhook integration (POS pushes changes) or frequent polling (signage checks for changes). Most integrations support real-time or near-real-time updates.
How do I show 86'd items on digital menu boards?
When items are marked unavailable in your POS, the integration can automatically hide them from menu boards, display them as 'Sold Out', or gray them out. The best approach depends on your preference—hiding keeps the menu clean, while showing 'Sold Out' indicates popularity. This automation eliminates the need for staff to manually update signage.
What POS systems integrate with digital signage?
Major POS systems with digital signage integration capabilities include Square (Catalog API), Toast (Menu API), Clover (REST API), Lightspeed, Revel, and TouchBistro. Even POS systems without APIs can often export data via CSV files that signage systems can import on a schedule.
How often should POS data sync with digital signage?
Sync frequency depends on how often your data changes. For pricing and availability, real-time or every few minutes is ideal. For menu structure changes, hourly or daily is usually sufficient. Most integrations use webhooks for instant updates on critical changes while polling less frequently for routine syncs.
POS integration transforms digital signage from a manual content system into an automated, always-accurate extension of your operations.
