The breakthrough consists in the development of a special standing scanner (QK-11). This scanner operates with a two-dimensional matrix-ccd-camera system which enables it to read QR-codes of LC-displays regardless of resolution, colours, or reflection. This is the basis to turn mobile phones into information carriers for encoded signals. The range of applicability is wide.
E-Ticketing, the electronic sale of tickets, is an important target area. Potential fields of application are plane and train tickets, tickets for the theatre, concerts, sports events or skiing permits.


There are numerous examples: Trade companies such as Lawson or AM/PM employ this innovative method of paying for E-payment as does Coca-Cola in cooperation with vending machine manufacturer C-Mode.
The Japanese airline JAL relies on two-dimensional barcodes for the sale of flight tickets.
These processes can be technically realized because of the support of the Japanese telephone company NTT.

The visitors of ID World in Barcelona from November 17-19, 2004 could experience how easily QR-codes operate during big events.
