read the first part hereLinear BarcodesLinear barcodes are commonly referred as first generation barcodes. These barcodes consist of vertical lines at specific gaps resulting in a particular pattern.  Hardware scanners are used to scan these patterns and decode the information stored in those particular patterns. These barcodes are also commonly called discrete, one dimensional or UPC barcodes. The examles of linear barcodes are  Code 39, EAN-8, EAN-13, EAN 128, UPC-E,  UPC-A, ISBN etc.Advantages of Linear Barcodes• In [...]
read the first part hereLimitations• It is not suitable for items which require large amount of information to be encoded. In that case, length of the code 39 barcode becomes too large which is not appropriate for encoding as well as decoding.• Code 39 barcode can be easily damaged and distorted like any linear barcode.Usage• Code 39 is commonly used in store items, inventories, badges and similar everyday items.• It is widely used in health [...]
