Ever since the U.S Government introduced the UID system of product and asset identification, there has been numerous productions of barcode scanners to verify UID Bar codes. UID scanners are simply verifiers used to identify the codes attached to individual products. These bar codes are different and unique to each of the items. UID scanners check the products compliance to MIL-SPEC-130 and the special programming in the programmers makes them capable of recognizing certain symbols, signs and other unique features that are made on the bar codes of the specific items. These scanners play a vital role of verifying and validating information encoded on the bars of these items.
Actually, there has been many manufacturers of bar code scanners and all the scanners have an extent to the kind of information that they can recognize on the bar codes. Some of these scanners are highly advanced and can retrieve essential information even from some of the most complicated bar codes. Also, the scanners also pose differences in accuracy of code reading and smoothness of their functioning. In US, UID verification is very important for items of high value. The Government requires that these items have bar codes before they are sold. The initial objective of Government introducing bar codes on such items was to keep track of all the products produced and owned by the Government. However, this tracking system was adopted by manufactures and many of the products in the market today have bar codes and serial numbers for identification.
UID bar codes are very essential as they contain all the vital information about the company that manufactures the product as well as the specific type of the product. The UID codes are primarily used for identification by use of unique serial numbers. UID bar codes not only play a role in tracking of the items by are as well used in separation of products in to different categories. Bar codes thus helps maintain records for the products. The categorization of items using bar codes is majorly done using the price or value of the item.
UID bar scanners simply read UID codes and labels. There is quite a range of scanners that are reviewed differently by manufacturers. Before buying any scanner, it’s important that you consider a number of factors such as the level or ability of the scanner in accessing or retrieving the information encoded in the bar, ease of repair and replacement costs of the scanner. Of importance, the scanner should be user friendly. The scanner should also have essential features such as a set up software, photo capture, ability to support 2D barcode and must be able to validate UID using UII output. Of importance a bar code scanner must support custom applications and have an onboard for data look up. The scanner should as well be able to store the encoded information in a systematic manner and allow accessibility of the data at a later time. With the ever increasing importance about UID bar codes, modern bar scanners are able to read encoded data in the labels beyond existing formats.
