I have just downloaded the Android app of Syska Gadget Security for my mobile. But on the first screen, it's asking me the 8 digit coupon code and 8 digit barcode which I don't have.
This is a paid application which means the only way to activate it is with a coupon that's given to you after you buy a plan from the official website. The app is not free to use, though.
Access the buy page and then choose one plan that suits you the best: http://www.syskagadgetsecure.com/Plans.aspx
A code will be sent to your email and then you'll have the possibility to register and have access to the application.
