Kaywa
Kaywa started with mobile tagging in 2005 and popularized the QR Code in the West. At its core this means the Kaywa Reader and a QR Code API and QR Code management solution. Several value-added services to demonstrate the power of the QR Code for our mobile present were added: DokoDare, a social location based service; Kaywa Ticket, a mobile ticket and ticket scanning solution; Scanvenger, Scavenger Hunts with QR Codes amongst others.
