Why Wireless Bluetooth Biometric Fingerprint Scanner working better than USB fingerprint reader with Android Devices?

Here we will list several below  two points to explain:

1)As everyone knows that USB fingerprint reader is mostly popular for windows computers in the first stage, USB2.0 for data transfer is quick for doing authentication. But due to different user cases, there is a high demand for using with android devices to do authentication on field. then comes out micro-USB version for android devices. The problem is not all android devices supporting OTG for data transfer, only the expensive ones support OTG.

2) Each android smart phones have Bluetooth available, no matter Bluetooth 2.0 or 4.0BLE, so this makes Bluetooth fingerprint reader more practical in field use. At the meantime, the Bluetooth fingerprint reader also supports USB port to laptop authentication as well.

From SFT company, we will offer Biometric Fingerprint readers full set of free SDK/APIs for both Windows drivers and Android.

Below is a video to show exact how the Bluetooth Fingerprint Reader is working perfectly with windows and Andorid.
