aztec | 2d barcodes

AZTEC – Excellent for viewing on cell phones and PDA displays:

QR code | 2d barcodes

QR Code – Marketing & Transportation applications:

datamatrix | 2d barcodes

DATAMATRIX – a square symbology, of varying densities used extensively in part marking and document ID as a large number of characters can fit in a small space:

pdf 417 | 2d barcodes

PDF417 – can be printed at a variety of aspect ratios and densities. Used in transportation, manifests, and personal ID including state driver’s licenses.

2D Barcodes can serve as portable data files, enabling the user to access information such as lot processing, shipment manifest, and serial number/sku data remote from the network database.

Most 2d codes require an imager, which algorithmically processes the image. Imager scanners are effectively digital cameras with integrated processors and therefore can also capture images such as signatures. As with linear barcode scanners, they can interface as a keyboard or serial emulation device, via USB, PS/2 or serial connection
