Ever because the old Codebar barcode utilized within the 1st automated library systems to the recently developed Intelligent Mail Technique as well as the information-rich PDF417 barcode, there are many distinct alternatives available, depending on what your application is and how very simple you would like the barcoding method to become. Basically deciding upon a 2D barcode mainly because it retailers a lot of info is blind towards the cost of implementing a 2D barcode scanner or other imaging options, to not mention the special decoding computer software you might ought to operate the whole program.
So what is available when it comes to barcoding technologies, how will it advantage your enterprise and most importantly, how much does it price? All this will depend on what you might would like to retailer around the barcodes and whether or not you’d like to make by far the most of your most up-to-date technological innovations to have essentially the most out of carrying details along the provide chain.
Very first of all, the barcode symbology, or the kind of barcode, is basically a common way of encoding ASCII (letters and digits) into a format readable by devices that capture light and procedure its formation, also knowns as a handheld barcode scanner.
Several with the goods you see around the shelves are EAN-13 or EAN-8 format, known as a 1D barcode, readable by all laser barcode scanners and CCD barcode scanners. These barcodes are very simple in their structure and just include a string of numbers that are ordinarily placed underneath the barcode. If the EAN-13/8 barcode is damaged, the user can input the barcode into a POS for instance and the outcome may be the identical. This quantity (or ID) is normally assigned to a solution or piece of stock information, generated automatically by the stock handle application or assigned manually as stock arrives in to the warehouse.
For inventory management, this kind of barcode is useful due to the fact you could control what those barcodes represent and study them easily with any type of barcode scanner or PDA device. This results inside a low-cost, very easily implemented remedy which will quickly save time and improve productivity in an environment which has access towards the similar solution details and IDs (usually in a corporation that shares a solution database but may have numerous websites).
A single obvious challenge together with the the EAN-13/8 along with other 1D barcodes such as Code 39 is the fact that the details stored inside the barcode is dependent — which is it must relate to some thing else. One example is, if a piece of specialist equipment is sent from the supplier to a organization that don’t hold popular product facts databases, a 1D barcode that contains a 12-digit quantity won’t hold any value to that business enterprise. Thus, all of the product info, including specifications or whatever else that the firm will must know when getting that piece of equipment, will should be incorporated within the barcode itself.
2D barcodes are much more complex in their physical structure and also the style of details they hold, understandable when you look at the truth that up to 2000 characters can be stored on a PDF-417 barcode or as much as the physical restraints on the printer on a DataMatrix barcode. Consequently, these barcodes are considerably more appropriate to compensate for the downfalls of a 1D barcode. Even so, 2D barcodes can only be read by a 2D barcode scanner or a CCD barcode scanner, the latter capturing the 2D barcode as an image and processing it applying software program algorithms.
The best use of 2D barcodes are after you choose to transport the information associated with that solution independently. In other words, we do not need to depend on the receiver of the goods to hold a shared database that should translate an ID into item information and facts – all the information stored about the item is held on the barcode itself. This is specifically beneficial in postal situations, exactly where a 2D barcode would hold names, postal addresses and return addresses. The receiver of this information could effortlessly use a CCD barcode scanner and retailer this facts for future purposes into a relational database, thus enriching their inventory management method with speak to information etc.
The PDF-417 barcode may very well be perfect for this idea, but what if you need to recognize incredibly modest pieces of gear for instance a circuit board? As a consequence of the nature of your algorithms utilized to create PDF417 barcodes, you might only have the ability to make around 170 bytes per square cm. With a DataMatrix barcode, on the other hand, the numbers of bytes stored is basically dictated to how correct your printer can reproduce barcodes at their smallest size. Resulting from this restriction, it really is recommended to work with only the highest high quality thermal laser printer for such a job.
Applying a High quality Barcode Scanner
Not merely that, the 2D scanner you decide on to scan the barcode with, whether or not it can be a red laser scanner or even a top quality CCD barcode scanner, is very vital. If the barcode is also modest as well as the CCD imaging technologies is not as accurate, errors will take place inside the scanning course of action or the scanner will basically not recognize the barcode. For instance, the Symbol DS7600 barcode scanner can read a datamatrix barcode as little as 1.1 inch working with its 1.3 megapixel CCD sensor.
So, with 1D barcodes, the considerations are fairly straightforward – decide on one of the most acceptable barcode and use a normal laser barcode scanner or CCD scanner. Even so, with 2D barcode scanning, you are going to should choose a barcode symbology that is compatible along with your application, pick a barcode printer that can be as much as the job and lastly select a scanner that should be able to cope with tiny barcodes if need be. Do not let the myriad of selections scare you aware from employing 2D barcode technology but be aware of what you should contemplate when implementing such a resolution.
