LeData is a scanner coupled with a person-to-person sharing functionality. Scan some text or a barcode, 1D or 2D barcode like a QR code, from your surroundings, and save it. Once saved, the actual piece of data you just scanned can be copied or edited, even if it was a VCard, and, most importantly, you can share it back any time with someone close to you by showing a QR code of the data with your phone.
You can also manually add any piece of information in LeData, which can become very handy to give, say, your complicated email address to someone without having to spell it out, or, of course, to share your own VCard or Mecard.
The Quick-share functionality allows you to quickly share a piece of information you would like another person to have electronically, even if it was not already saved in your Data section of the app.
So start taking control of your scans, and show those QR codes!
