Optical transaction technology specialist, MetaSepia, unveils ScreenBeam, a ground-breaking optical alternative to rival mobile near field communications (NFC) services by enabling fast, frictionless and secure transactions between on or offline devices.
Unlike mobile NFC, which relies on transformer-based radio frequency (RF) fields to couple devices, ScreenBeam authenticates visually, displaying and capturing authentication data using the devices’ display screens and onboard cameras.
