The RFID Weblog: Is 2-D DataMatrix barcode a serious competitor?

Is 2-D DataMatrix barcode a serious competitor?

Filed in archive Implementation by ehsan on August 19, 2006

As the price of rfid tags are still too high for many companies looking for tracking Technologies, a series of other competing Technologies are trying to catch up and one of them is 2-D DataMatrix barcode.

In the past, some problems regarding the use of traditional barcodes made companies migrate to RFID. Among those problems, it can be mentioned that, the dirt, water and humidity rendered many of the codes unreadable. On the other hand, high cost of RFID tags, software and high-end enhanced readers was also a challenge which still exists today.

By the way, some companies such as ImageID Ltd., with their 2-D DataMatrix barcode solution, claim that they have combined best of the two world and offer reliable, low cost tracking technology. I myself am not quite sure that whether this is a serious threat for RFID or not in the long run but it may definitely be in the short term till RFID tags become cheap enough to dominate the market. What do you think?

The prime justification for using RFID over barcode is the ability to read large groups of objects (a pallet load of goods) simultaneously. The failure to accurately achieve this goal was predictable. See following link:
http://www.aidc100.org/RFID-vs-Bar-Codes.344.0.html

Results from several pilot applications have shown that the accuracy for group reading with RFID is between 50% and 80%. This has forced current users to read each object as it is selected into the group, and link the data to a new group identity (Aggregation). Subsequently, the group can be tracked by reading its singular group identity code.
The substitution of the DataMatrix code for RFID suffers from the same deficiency. Imagers will probably read groups of objects with less accuracy then RFID. While it may be less expensive, it will not work any better.
If the AIDC problem is reduced to reading objects one at a time (Singulation), then linear barcodes are cheaper, and more accurate. The only reason to use 2-D barcode is when the object to be tracked is too small for a linear barcode, and there are plenty of objects in that category. The use of 2-D barcode for large objects is misguided.
