Denso Corporation, part of the Toyota group

involved in the evolution of bar coding technology has developed a newer

and more advanced technology called quick response (QR) codes or

two-dimensional barcodes . These have been approved and accepted by the

world regulatory bodies. The Bangalore-based Essae Technologys have a

strategic tie-up with Denso Corporation and now offers these

two-dimensional in India.

The two-dimensional barcodes can hold more information than a regular

barcode, in a much smaller area. These codes not only store more

information but they are encrypted as well. To the naked eyes it looks

garbled containing small dots and squares but when scanned using the

specialized scanner only then are the details revealed. Unlike normal

barcodes, which need to be scanned from a particular direction, these 2-D

codes can be read omnidirectionally and do not have any alphanumeric

characters printed.

The 2-D codes find its applications in Shipping, Freight,

Pharmaceutical, Networked transactions, and Inventory and Warehousing

sectors. Just by using a 2-D code, invoices, balance sheets and other

sensitive documents can be faxed in a networked multi-site/interoffice set

up eliminating security risks. For shipping and pharmaceuticals, packing

details, which would be quite elaborate, can be packed into a tiny 2-D

code. Purchase orders, production instructions, packing instructions can

be delivered to the assembly lines for efficiently executing complex

manufacturing processes.

These codes could be used as a substitute for text documents (say MS

Word 97) the text can be encrypted into 2-D codes and be carried instead

of all the actual documents print out. The scanners, which are compatible

with PCs or laptops can be used to reconvert the codes into text.

Typically a travelling executive could carry 5 sheets of 2-D print outs

instead of hundreds of sheets of paper.
