2 new models of USB adapter were released by Sanwa Supply. Both are ¥5,800.
They are compatible with TransferJet technology (Close proximity wireless transfer technology), which instantly enables them to send/receive data to/from another device just by putting the device above them.
In these adapters, Sony's ultra-fast LSI is built-in so they are capable of sending 50MB data to other devices in about 5 seconds. In addition to that, using close proximity wireless transfer technology lessens the possibility of data leakage.
