If the item moves out of range, the owner is alerted through the 'Rope' feature, and nearby phones can help detect the object through Bluetooth via the 'UHelp' feature. A fascinating feature for iFind is that shaking the iFind tags will cause the phone to vibrate, WeTag said.
The difference is that the iFind tag does not contain a battery and is powered by ambient electromagnetic radiation, WeTag says. "It recycles electromagnetic energy and stores it in a unique power bank. This exciting feature frees you from the trouble of charging batteries or replacing them through the manufacturer," say the makers on the Kickstarter page.
For US$16, a backer is entitled to one locator in one of a dozen colours. Overseas shipping costs US$10.
