Cloudpin pioneered the transfer of content from device to device using a unique identifier. In particular, rather than relying on the need to share complex and often personal information in order to transfer files from device to device, Cloudpin allows phones to simply communicate a PIN. This PIN allows complex forms of data to instantly transfer from and to multiple devices at once. When combined with location based transfer techniques, Cloudpin truly revolutionizes person-person communication in the digital era. https://www.google.com/patents/US20150288760?cl=en http://www.crossroadstoday.com/story/34951378/q-technologies-receives-notice-of-allowance-for-its-location-based-sharing-using-a-unique-identifier-patent
