Once you have clicked the link in the email after purchase, follow these tips to get an accurate scan: 1. Hold the phone about 1ft away from your leg. The scanning screen will be purple if it is focused. 2. Move slowly across the area in one pass to be scanned. The entire scan should take about 10 seconds. 3. Make sure the finished scan captures the entire desired area. Check out this video for a walk through and example! https://youtu.be/HYeTj52WCzA
