Hunter's comment
Xender is one of the essential Android apps you should have on your device. There is no need of usb cable to transmit or recieve data. It is more faster then bluetooth and much relaible.
With Xender, you can exchange basically anything from your Android: contacts, records, pictures, music, recordings, and even applications. You should simply make an exchange and furthermore (clearly) be near the client you need to exchange documents to. This is vital Xender just works if the individual you need to exchange records to is close-by.
