Furthermore, the inconvenience of losing a flashdrive is erased by moving the device to one’s wrist and working wirelessly. The TekBand greatly increases the convenience of using these two devices by moving all functionality to the wearer’s wrist, revolutionizing the way people use cell phones and USB flashdrives.
