This USB OTG (On-the-Go) adapter cable is ideal for connecting standard USB smartcard readers to smartphones, tablets and other mobile devices that only have micro-USB connectors. In order to operate correctly, the mobile device must have suitable hardware and O/S-level support for USB On-the-Go, as well as suitable drivers for the reader.
Many contact and contactless smartcard readers that operate using the CCID protocol are known to work well on Android when combined with OTG-capable hardware and suitable application software. Other USB devices that operate as mass storage or keyboard emulation can also be used with this adapter.
This cable has 1 x USB 'A' female socket and 1 x micro-USB 'B' plug and is approximately 14cm long end-to-end.
