|John McLear -inventor of NFC Ring|
John McLear decided to run campaign on kickstarter in order to fund his new project related to the NFC technology. The idea of the project is sharing information in an easy and fun way, by the special ring. NFC Ring has two inlays, public and private. NFC Ring has 2 sensors (1 for public use and another for private use) and have no need to be charged.
As such it can be used to various daily tasks: unlock smartphone that supporting NFC, locks or unlock NFC doors. Ring allows to share links to web sites or WIFI passwords or even contact information.
Software that comes with NFC Ring is open source, meaning you able to create programs or application for your own use.
Kickstarter crowd funding model proved itself for many successful projects that chose it as alternative to the angels and VCs. In case of John he sets £30,000 as a goal, but succeeded to rise £240,000.
