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.

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).
