First off, all those present were required to sign an NDA specifically related to the more obscure technical details (the explicit technology used in the device). Much of this technology is proprietary to Megion, and is not available anywhere in the world. Everything apart from explicit technological details we are permitted (and encouraged) to convey and communicate about.
Can you tell me if the mesh network uses any existing tech, such as Dash7?

The mesh-network range of the device is 200-300 meters in open air, less if there are walls or other interferences.
Excellent, this is the practical minimum of an urban mesh network, in my opinion.

Some people on the forums have (probably correctly) said that the alleged features of this card are impossible using any existing technology. This is because Megion’s technology is not available on the market. Again, Megion’s engineers developed many of the components in-house. What is in this card is better technology than what is available in the marketplace.
I doubt this statement. As a ham myself, I've seen some pretty wicked tech that is hard to find in any commercial marketplace; but that doesn't mean that it couldn't in a hurry.

The devices hold private keys on them. These can be backed up via the company’s website, but it is not necessary to ever interface with the company in order to use the device. In other words, someone can use the device anonymously and without creating any accounts anywhere.
This feature concerns me. I'd rather have a device that was not replicateable at all than one that permits the company to do it via a distant server. Even if the device asks for user permission, that does not mean that it must.

If you lose the card and have not backed up the keys, your money is gone.
Which would make it no different than a regular wallet.

The cards will cost, based largely on production quantities, in the range of $10-$25 each (retail).
Not as cheap as I had hoped, but not unreasonable.
An unaddressed question. In the video it mentions the capacity to send arbitrary text from card to card (text messaging), did you see evidence that this feature is real?
