Place the sticker on your vehicle's windscreen or the back of your phone to alert paramedics that your In Case Emergency info is on your usb. Bike riders place the sticker on your windscreen or helmet. Basically put it anywhere that it's obvious. I have one on my mobile phone cover and one on the windscreen of my car. 

The sticker is self adhesive and UV treated. The size is 5cm across.
