POS-Touchscreen-Technologien im Vergleich: Resistiv vs Kapazitiv vs SAW vs Infrarot

Four touch technologies turn up in POS — resistive, projected capacitive (PCAP), surface acoustic wave (SAW) and infrared (IR). For most modern counters the answer is PCAP, but the “best” one is set by your environment: gloves, wet hands, kiosk size and stylus use all swing the choice. Quick orientation:

Each technology senses a touch by a completely different mechanism — and that mechanism is what dictates its strengths:

Laid side by side, the trade-offs are clear. Read down the column that matters most for your site:

Translate the trade-offs into a choice with a short decision path:

Each technology fails or degrades in its own way — worth knowing both to choose well and to maintain what you have:

When a touchscreen fails, you usually don’t replace the whole monitor — the touch layer and the LCD are separate:
