Tylt Capio with NFC
Smartphones attach to the Capio via a patented adhesive. Only {silicone and rough materials} won’t stick to it; if your case is made out of either, you can use the included support arms. Dust can cause the pad to lose its adhesiveness over time, but rinsing it with water will return it to it original state of stickiness.
