Encrypt Mail Cards two uses cases qrcode messaging encrypted and encrypt decrypt email by lan encrypted laptop & NFC Phones & NFC Cards


Contactless encryption, end-to-end from an NFC card, between people, with their own encryption keys, which they manage, store, and use freely, anywhere, anytime, while remaining anonymous. No software, no email application, no server, no remote connection. You use your usual email like Gmail or ThunderBird and soon Yahoo and Outlook.

Best New International Innovation 2021

Our solution protected by two international patents breaks with all existing solutions. In fact, our method of safety and security is not only innovative but also unparalleled. The solution is not based on the use of remote servers, nor the exchange of keys via this type of service and even less on the storage of keys on computer and telephone systems.
In fact, messages and attachments encrypted via the NFC Encrypt Mail device are made via keys generated, stored and used totally outsource computer and telephone systems. So, even if the mail servers get hacked, it doesn’t matter. In the same way, it is not possible to read the content exchanged. In addition, the display of emails also remains encrypted effectively fighting against the risks of espionage and / or malicious looks. Anonymity is achieved end-to-end since outsourced encryption is life an extension on computer and a phone application. Its level of compatibility with free Webmail allows the user to freely create an email profile. Encrypt Mail Cards finally offers multi-authentication of users, unlike existing email solutions as secure as it is. The trusted third party is carried out via an NFC device whose encryption keys generated at the discretion of the sender are exchanged with trust criteria that he has pre-established. The criterion of trust is in fact realized from human to human via their device of which they have total control.

Secure control of the entire value chain

The research and development department are committed to making the Encrypt Mail Card solution the most secure hardware email encryption system in the world. This is why we design, develop and manufacture our software, applications, web browser extensions, electronic design, embedded system and manufacturing tools. We aim to control the entire value chain from idea to manufacturing of products and services.


Hybrid physical and digital security

Encrypt Mail Cards uses an ISO/IEC 15693 NFC component to physically secure access to the data stored in its eprom. The encryption keys are stored encrypted with trust criteria, some of which are defined at the discretion of the user. In addition, at least one of the trust criteria is not physically present in the device. This makes it possible to resist an invasive attack. Thus even if the physical access security is corrupted, the data stored in the memory will always remain encrypted.

Differentiating added values

Authentication has multi configurable trust criteria + End-to-end encryption from an NFC device + Hardware guardian of encryption key in an electronic device + Encryption key manager physically outsourced + Encryption on existing email service + Mail always encrypted even when they are displayed

Some added values that break with the existing
