Denso - QK30 Series
2-Dimensional Mobile Phone BarCode Reader

The Denso QK30 Series Barcode Readers are specifically designed to read 1D and 2D barcodes displayed on mobile phone screens and printed on paper.

The QK30 is the only scanner in it's class to offer programmable multicoloured LED's and play audio files. This compact device is 50 percent thinner than previous models, yet has a 30 percent larger scanning area. Applications for which this reader is ideal for include e-tickets, e-coupons, access control and memberships.
