Identity

Identity gives you the opportunity to enter the world of QR codes, not simply decoding them, but also creating a sort of Virtual Business Card, grouping all your contact and professional data (i.e. Social Network accounts) that you can exchange directly on your smartphone screen with a presonalized QR code.
With Identity you can:
– Read and decode QR codes, save them (to be decoded offline!) and share their link
– Create and save new, custom QR Codes
– Join Identity free service to create your Virtual Business card
