Understanding The Technology Behind The 2d Barcode Scanner
Posted By on June 6, 2010
In order to decide on which 2d barcode scanner one needs for the job at hand, one may want to decide whether one needs such a scanner for personal identification and image capturing or for retail. For, while there are many scanners which read barcode information, only 2d barcode scanners have the capability to capture data, images and transmit same over an authorized data base. Therefore, most likely the barcode on the back of your identification or driver’s license is a 2d barcode.
Although many scanners provide imaging and laser technology, these special 2d barcode scanners read a great variety of information related to both personal identification and information. As such, these scanners are often used by the postal service and other package shipping companies worldwide. Therefore, these scanners allow individuals the ability to track their packages online and know when a package has been shipped, the current location and when it is to be delivered, often simply by entering a tracking number into a form on the company website.
However, as different scanners are required for different applications, one may need to purchase multiple scanners depending on needs of use. For example, as each scanner has a different purpose such as postal, retail or package tracking, there are different models for each use based on the hard codes each scanner can read.
As these scanners read a broad range of symbology which are derived from hard code programming, one must use the right scanner for the desired application. These can include, but are not limited to, Aztec, Datamatrix and PDF417. While there are differences among the different units, all 2d barcode scanners include imaging and laser technology. As these devices can scan images along with having the latest laser technology, these scanners have now become an everyday part of retail operations worldwide.
Today, these 2d barcode scanners are also being used in the postal system in order to easily track packages whether being shipped domestically or overseas. As such, one can know where the package on sent is at any time during the journey if one has requested such details at the time of shipment. Several packaging and shipping firms use this technology today and find it very useful in keeping track of local and long-distance deliveries related to same.
In addition to the standard 2d barcode scanner, one can also find cordless bluetooth and industrial scanners which read both 2d and linear technology. At least two of these 2d barcode scanners feature these operations. Whereas, one may want to ask whether other models have the same features or not since the feature is not common on most. Last but least, now coming out are the scanners which feature personal identification confirmation features and other data transmission abilities. These no doubt will be a quite popular choice both now and in the future as the world experiences more and more problems with identity theft and other related issues.
So what defines a 2d barcode, it depends on the code. For example, a datamatrix is a square symbology which features varying levels of density used in part making as it allows a large percentage of numbers to fit within a confined space. Whereas the PDF417 is based on printing aspects along with ratios and densities and is most often used in transportation manifests and personal identification such as driver’s licenses and other legal documentation.
Each code used in this technology, the Aztec, MAXICODE and QR code are also 2d barcodes which are still being used today. These codes provide easy access to confirm a code is valid either from a local or remote location. Although, one must provide the correct user names and passwords before signing into such a system. Though once in, the personal information and other data can be readily accessible at an given moment which makes these scanners great for providing service to individuals at remote locations worldwide.
