Sorry, this sounds a lot like spam.
New poster, and having just searched YouTube (why YouTube? Why not provide a direct link to a website), the only video that comes up in regard to the flight crew register shows 9 views as I type this and has only been posted today.
The website, very amateurish and made in Wordpress, wants to charge you 28.50 GBP (yearly) to sign up/get a card. It doesn't ask for an employee ID, and why ask for a discount if it's the cheapest out there (FYI a real aircrew card is free from your employer, or included in an AOPA membership, last time I checked)
Also not sure if hotels and other discount providers will accept the card, probably cheaper to just make one up yourself.
