USB On-The-Go (OTG) is a standardized specification for USB 
connections that allows a device to read data from a USB connection 
without requiring a PC. The device is basically becoming a “USB Host”, 
which isn’t an ability every gadget has.

What 
can you do with it? A lot of stuff, which we’ll detail later! For 
example, if you want to connect your USB drive to your phone, or maybe 
use your android tablet, USB OTG can make that happen.

USB On-The-Go, often abbreviated to USB OTG or just OTG, is a specification that allows USB devices, such as tablets or smartphones, to act as a host, allowing other USB devices, such as USB flash drives, digital cameras, mice, keyboards, to be attached to them. Use of USB OTG allows those devices to switch 
back and forth between the roles of host and device. A mobile phone may 
read from removable media as the host device, but present itself as a USB Mass Storage Device when connected to a host computer.
