The top up card is used to create and bind a license for your vidon box, and then you will be able to use membership features on that box.
If you are getting two top up cards, it means you have brought two vidon box. For the second top up card, you can:
1. Use it yourself and bind it to your second box. Then you have two boxes under your account that can use membership features.
2. Or you can gift the top up card to your friend and give the second box to him/her, so your friend can creat a new account and use that top up card on the second box. Then you will have one box under each account.
The 'gift' top up card feature is not online yet, but it will be ready before you've received your box.
We will be given a complete guide on how to operate them, for now you can check the support centre on our website.http://www.vidon.me/support.htm
the info on our new membership page will also help you understand how it works.
