This article provides an overview of the different Elo touchscreen technologies, including how they work, their benefits, and common applications.

IntelliTouch / SecureTouch (SAW)

IntelliTouch and SecureTouch are Surface Acoustic Wave (SAW) technologies that use ultrasonic waves across a glass surface. A touch absorbs part of the wave, allowing the system to calculate the touch location.

Key Benefits:

• Flat, all-glass surface
• High accuracy and stability
• No bezel required
• Durable, tested to 50M+ touches

Best For:

• Public environments
• Interactive kiosks
• Retail and banking

AccuTouch (5-Wire Resistive)

AccuTouch uses two conductive layers that make contact when pressure is applied. The controller reads voltage changes to determine touch position.

Key Benefits:

• Works with gloves, stylus, or finger
• Resistant to dust and liquids
• Stable and drift-free
• Supports sealed designs (IP65/NEMA)

Best For:

• Industrial environments
• Medical equipment
• POS and kiosks

PCAP (Projected Capacitive - TouchPro)

PCAP technology detects touch through an electrical field and supports modern multi-touch functionality with fast response and high clarity.

Key Benefits:

• 10-point multi-touch
• Fast and responsive
• Excellent clarity
• No drivers required (HID compliant)

Best For:

• Modern touch applications
• Interactive signage
• Self-service kiosks

Infrared (IR)

Infrared touchscreens use a grid of invisible light beams. When a touch interrupts the beams, the system determines the touch location.

Key Benefits:

• No overlay, maximum clarity
• Highly durable and rugged
• Works in extreme environments
• No drivers required

Best For:

• Large displays
• Industrial environments
• Harsh conditions
