Seos is an open technology that enables any smart device to become a trusted credential, replacing mechanical keys and access cards using wireless technology, such as NFC or Bluetooth, to open doors in homes, hotels, offices, hospitals, universities, industries and commercial buildings.
Seos is used for issuing, delivering and revoking digital keys that are delivered with end-to-end encryption and stored securely on SIM cards, embedded secure elements or Micro SD memory cards.
