Qwantum Private Messaging is a cloud-based application designed to enable its users with the ability to encrypt and decrypt sensitive data. The application works with MagTek Card Readers and Qwantum Cards to provide a powerful authentication experience that does not rely on usernames and passwords. Qwantum Private Messaging is organized as a club so that it can grow and flourish by attracting like-minded professionals who see value in privacy, do not intend to use the service for unscrupulous activities, have business needs to establish the authenticity and integrity of the documents, and objects they rely on, and desire to trust with confidence those with whom they share sensitive or confidential information. To create a Private Message, simply glide your Qwantum Card through your MagTek reader or use a Member or Guest Token. Once authenticated, you can create your message, choose to add an optional attachment, designate your recipient(s), set an expiration date, and choose the level of audit detail you desire, then press email or download. The Private Message is created, encrypted, and delivered to the designated recipients. Our mission is to build a network of trust based on these timeless principles: Privacy, Integrity, and Authenticity.
