The self-service borrowing and returning function of readers reduces the workload of administrators and improves the service level of the library. The security door system automatically reads the borrowing and returning of books, effectively preventing books from being stolen.

There are many types of barcodes, how to choose a barcode

There are many types of barcodes, how to choose a barcode? Today I will teach you how to operate and use the steps.

Method

- Code 128 barcode. The code128 code is suitable for the logistics industry and the transportation industry. It is used for ordering or distribution. It is a compact high-density barcode that can be composed of letters and numbers or only numbers. The 128 barcode is named for its ability to recognize all 128 characters of ASCII. At present, the 128 barcode is widely used around the world and is suitable for non-point-of-sale products, such as container identification codes in the transportation industry.

Its scope of application is: warehouse management, logistics industry and transportation industry.

- EAN barcode. The EAN code is the European Article Number, which is applicable to retail goods worldwide. If you are selling international products, then the EAN barcode should be listed as your first choice. EAN barcodes are applicable all over the world, including EAN-13 and EAN-8, both of which are composed of company number, project reference and a single checksum. EAN-13 is the original 13-digit format. EAN-8 is an 8-digit compressed version suitable for small products.

Its scope of application is: retail industry

- Universal Product Code (abbreviated as UPC barcode). UPC barcodes are usually applied to sales items at retail outlets around the world to scan and record sales information of retail products. UPC barcode is the most original barcode format, which was first developed and used in the United States. It has been widely used all over the world and is suitable for relatively small products.

Its scope of application is: retail industry

- ISBN (International Standard Book Number). ISBN (International Standard Book Number) is a 13-digit linear barcode developed for non-serial publications, including fiction, non-fiction and e-books. Through the ISBN system, whether it is a physical bookstore, an online bookstore or a library, you can check the version of a book (excluding reprints), and it is applicable internationally.

Its scope of application is: non-serial publications (such as novels)

- ITF barcode (interleaved 25 code). ITF barcode, also known as intersecting two-five barcode, is composed of 14 letters of numbers and is suitable for commodity transportation packages around the world. Because IFT barcodes can handle high printing tolerances, they are ideal for corrugated cardboard or other poor-quality outer packaging.

Its scope of application is: commodity packaging

- Code39 barcode. 39 bar codes are widely used in products in many industries, and the most used are the automotive industry and the US Department of Defense. The 39 barcode allows the use of numbers and characters, so it got its name because it could only compile 39 characters at first, but now its character set has increased to 43. Its biggest disadvantage is that the data density is low, so it is more suitable for smaller commodities.

Its fields of application are: Automotive industry, Ministry of Defense
