Digital Tattoo Unlocks Phone
Mobile phone manufacturer Motorola has teamed up with US electronics firm VivaLnk to develop a temporary skin tattoo that can be used to unlock a smartphone.
Digital Tattoo uses a super-thin near field communication (NFC) circuit to communicate with the Moto X handset. Wrapped in medical-grade adhesive, it stays attached to skin for up to five days. The tattoos are available to buy in packs of 10 for $9.99, and are currently only compatible with the Moto X.
The tattoo is designed to make it easier and quicker for users to access their mobiles. Unlocking a phone using a preset security code takes 2.3 seconds each time, according to Motorola – and the average smartphone user unlocks their phone an average of 39 times a day. To save time, more than half of users have simply not set up a security code on their device, leaving their personal data vulnerable.
Meanwhile, gestural unlocking systems such as Knock Unlock are gaining ground among consumers with 'password fatigue' – particularly in light of the massive internet security bug Heartbleed discovered earlier this year.
