Boris Landoni from Open Electronics writes about a new open source project the LEWE, a wristband that reads biometric:
The Lewe project aims to collect and use available technologies to make a low cost idea that is applicable to all sectors using sensors for data collection. This project goal is the development of a communication protocol, named Jack, able to transport data reliably making communication between multiple devices easier and real-time.
All this could be found in a wristband that reads biometric to be sent via bluetooth to an Android smartphone and, through it, to an online cloud for data storage and organization.
