Multi-function data key
A data key for secure financial and other types of data transactions with a key-shaped case, lightbox touch sensor carrying a removable wafer, processor, secure memory, general-purpose memory, battery, antenna, speaker, microphone, and a dual-purpose USB and chip pin pad. Bluetooth, NFC and/or RFID provides the ability to pair the data key through a wireless channel with another device, such as a smartphone, using a pairing button on the back of the data key. The data key provides chip-and-pin type security to online financial transactions. Dual-device security requires both the data key and another communication device registered to an authorized user to be present to activate the data key for secure operations. Device pairing enables geo-proximity features, such as dual-device security with a paired device, key finder, phone finder, and panic button. The data key may provide secure, remotely programmable security for building and equipment access.
