IndoorGPSguy writes "Gigaom is reporting Boston-based startup ByteLight has launched a new product called LFC (Light Field Communication). This technology is a new alternative to NFC. It works by transmitting data through an LFC terminal, which is then picked up by the camera on any smartphone. Customers can tap their phones for mobile loyalty programs and mobile payments. It works on any smartphone with a camera, unlike NFC, which doesn't work on iPhones. Gigaom writes: "According to ByteLight, the advantage in using LFC over NFC isn't just accessibility (nearly all smartphones have cameras while NFC chips are harder to come by), but also expense and flexibility.""
