The integration between technology and the human is increasingly intense starting to have an essential role in the evolution of communications. In this context, wearables are increasingly at the center of discussions related to the Internet of Things (IoT). The devices wearables represent a great opportunity for both manufacturers and developers. In this talk we will address examples of products with dressing technology as (sunglasses, watches, clothes, bracelets, shoes, components involved, etc.), operating systems that can be used and the relationship with IoT. We demonstrate an application of this concept through a wearable device being used in the security area, where through a qrcode we can have access to a particular environment.
