Scans and identifies the fingerprints of hand that is holding the device. Only after the scan is confirmed will the device will enter into the next screen.
Device stores user’s fingerprints into it’s memory only allowing the same fingerprints to gain access to the card. User then enters the fingerprint pattern which is also stored in the memory.
No third party involved in inputting applications on device. User logs in onto respective company’s secure online account, connects device and the PC through USB connection
Save picture, wallpaper, or note on welcome screen which appears right before fingerprints are scanned. Device automatically turns off after 8 seconds of inactivity. Incorrect fingerprint pattern the device will shut down completely
Need a key code to establish a secure connection between the device and the computer to view the usage history
There were initial explorations of ways to provide users physical control of a multi-functional smart card before focusing on the interface
User research was conducted with the different paper prototypes that correspond to the different physical prototypes. Users liked the idea of a double check screen that asked whether what the user selected is what they actually meant. This gave the users a stronger feeling of control since if they were to make a mistake they would have another chance to correct it.
