Jakcom Smart Ring with NFC (Near Field Communication) capability - various sizes and colours
Using Smart Rings or NFC (Near Field Communication) to control, your smart devices, store information and maybe even open electronically protected doors, smart devices such as mobile phone and other digital PIN protected devices are becoming quite common now. Basically the ring has a smart chip and wirelessly interfaces with your smart device via an app. An example, use the ring to click the camera on your smart device for remote selfies. Basically you can use the ring to interface with any smart device you own and requires a PIN or digital password to open. You can program the ring via your smart phone or device to store important information such as Pins, credit card data and PIans etc etc so the ring when used around other NFC devices can be quite a clever tool. Store other info like your diary schedule (calendar), notes, word or other documents that can be accessed from your ring on a compatible smart device. It may take some working out, but the smart ring does have some functional applications and can be a lot of fun.
