read the first part here   Purpose It is one of the oldest and most widely used barcodes. The purpose of developing UPC was to develop such a shopping or buying system where salesperson does not have to manually enter the information of a product in the database. This saves time and minimizes human error unlike manual information entry. For this purpose, IBM developed UPC in order to ensure, quick, easy and reliable information encoding [...]

UPC-A and UPC-E UPC stands for Universal Product Code. It is type of linear barcodes and mostly widely used for retail applications. There are two variations of UPC • UPC-A • UPC-E UPC-A UPC-A is a variation of UPC and uses 12 digits for information encoding. Out of these 12 digits, 11 digits contain the product information while the last digit is the checksum digit. The eleven product digits are further divided into three logical [...]

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 [...]
