A USB flash drive with On-the-go (OTG) technology is equipped with a standard USB connector on one end, and a micro-USB connector on the other end. In this way, you can connect the USB flash drive directly to your smartphone or digital camera without using a cable, allowing you to read and transfer data quickly and immediately. By connecting the OTG flash drive to your smartphone, you will be able to view, for example, the files saved on the flash drive directly on your device, or transfer them from one memory to another according to your needs. You can then use the USB port of your flash drive to read or transfer data onto your computer. Currently, OTG technology is compatible with the Android operating system.
