Portable digital solutions provider Portronics on Friday launched Tring — a multi-purpose device to track your valuables like wallets, mobile phones or car keys. The Rs 999 Tring offers anti-lost key finder and a remote camera shutter function. You just need to pair Tring with your Apple or Android phone using “Tring Track” app. Tring is equipped with a very tiny speaker used for beeping when using it to find lost things. The device is dust and water proof, thus you can safely take it outdoors, the company said in a statement on Thursday.
