Serious game
You are a secret agent, you go on a mission. The head of the “Q” section gives you a card similar to a bank card. With this you will be undetectable and untraceable!
All the messages you send will be encrypted and unreadable except by the recipient! Series of letters and numbers exposed for all to see!
And how?
Because you create the encryption key and store it in this card. Only you have access to the card’s contents.
OK and how does it work?
Simply with your phone and this card. No battery, no cable, no charging.
And how does the recipient decrypt my messages?
With a similar device.
The data you send to the servers, the cloud or elsewhere will be unreadable by anyone, even the best hackers.
The card can be stolen, don’t worry. It’s a real safe, no one can access the content encrypted with your segmented authentication keys.
Good luck with your mission.
