Moto Z cover turns phones into walkie-talkies

A US-based startup has created a modular back cover for Moto Z smartphones that adds walkie-talkie capabilities with a range of 8 km. The latest Moto Mod to surface on Indiegogo is Linc, a “smart” walkie-talkie attachment that will allow you to stay connected in areas with no cell coverage.The cover also supports SMS, GPS location sharing, and an emergency alert button to transmit SOS signal. The accessory claims to have a battery life of 20 hours on standby.
