Los Angeles-based QR code startup ShareSquare is announcing today that it has opened up its QR code service to the public, and also outlined its pricing plans and tiers. The firm--which has been focusing in on musicians and bands with its service--allows customers to create their own QR codes through the site, linked to special online modules to promote those customers. ShareSquare has been in private beta for the last three months. ShareSquare said it will offer up to five ShareSquare mobile web apps in its free tier, up to 10 mobile web apps for its Pro ($99/month) offering, and up to 100 mobile web apps for its Enterprise ($499/month) service. The startup is headed by Matthias Galica.
