What's smart Bracelet?

Smart Bracelet is very similiar with Smartwatch, the difference between the 2 is that bracelet has small display or even no display, which likes a bracelet, while smart watch has a little bigger display, which likes a traditional watch.

A smart Bracelet is a computerized bracelet with functionality that goes beyond timekeeping. Early models can perform basic tasks, such as calculations, and game-playing. It can run mobile apps, using a mobile operating system like iOS or Android. Some smart bracelet function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth or USB headset.

While internal hardware varies, most have an electronic visual display, either backlit LCD or OLED. Some use transflective or electronic paper, to consume less power. Most have a rechargeable battery and many have a touchscreen. Peripheral devices may include digital cameras, thermometers, accelerometers, altimeters, barometers, compasses, GPS receivers, tiny speakers, and SD card (that are recognized as a storage device by a computer).
