It encodes digits in pairs, with the first digit in each pair represented by bars, and the second digit represented by spaces, so that they are interleaved. Two of the five bars or spaces representing each digit are wide, and the others are narrow. Interleaved 2 of 5 is included in the GS1 system as the ITF standard, which has a set length of 14 digits. Patterns identical to the start and stop code can occur within the coded data, which can result in a bad reading if the scanner does not read the code all the way across.
To prevent this, the ITF standard requires a heavy black border called the bearer bar. ITF barcodes are typically used in wholesale and shipping for box or carton lots of a product. A specialized version of the ITF barcode is also used on film canisters. Codabar was originally developed by Pitney Bowes in It is a variable-length barcode that uses a small set of bars to encode the digits 0 through 9, and in some applications, a few symbols such as the dollar and plus signs.
A Codabar code consists of a start symbol, the coded data, and a stop symbol. Codabar has traditionally been used by libraries, by blood banks, and for airbills by some companies such as Federal Express, and is still in use for some of those applications. APharmacode barcode consists of two widths of bars only, with a length of up to 12 bars.
The data is a single integer in the range 3 to encoded as a binary number. Pharmacode barcodes can use multiple colors as an added check for packaging accuracy.
Individual pharmaceutical companies generate their own Pharmacode barcodes. They are used on the production line, where they are automatically scanned on inserts and other items being placed in the package, in order to detect mismatches.
Databar is a GS1 family of barcode standards generally intended for reduced space applications. Linear barcodes in the Databar family include the Omnidirectional and Expanded codes, which can be scanned omnidirectionally, and the Truncated and Limited codes, which are designed to be read by handheld scanners only. Expanded codes can include additional information such as weight and expiration date, designated using Application Identifiers in the manner of GS barcodes.
Truncated and Limited Databar barcodes are generally used in the health care industry for small-item identification. Postnet is the barcode system which has been in use by the United States Postal Service for routing mail; it is being phased out in favor of the Intelligent Mail System, described below. Postnet codes use variable-height bars to represent digits. Postal Intelligent Mail Barcode. It is a bar variable-height code with four types of bar.
Stacked barcodes are linear barcodes which are divided into segments and placed one above the other. The stacked versions of the GS1 Databar codes use the same basic encoding as the linear Databar codes, described above, and are used in similar applications.
They are particularly useful for limited-space items with labels which have very narrow linear dimensions. PDF is a variable-height, variable-width stacked barcode made up of rows of short bars and spaces. It can have as few as 3 rows, or as many as All rows must contain the same number of data codewords, but that number can vary from 1 to The actual method of encoding is based on a complex system which uses about codewords to represent data in different formats.
This allows PDF to encode text, digital data in bytes , and large numbers within the same barcode. The same composition of the standard distribution code ITF is generally applied to "01". It consists of the EAN code of the packaged product and the package indicator that indicates the product quantity.
Since "delivery container code" has the same data composition as for the EAN code and the standard distribution code, it can be used only on the condition that EAN and standard distribution codes are not printed on corrugated cardboard boxes. The data of various dates are indicated. For the validity of quality, the important data necessary for management are indicated. For example, "open date" of foods and "drugs validity" of drugs. These are the application identifiers to indicate the administration data such as "order number" of customers and "customer's account code".
They are used for sorting goods according to destinations. What are 2D codes? What is a DataMatrix code? What is a QR code? The one guide you need to learn all about barcodes! Package number Quantity in package Weight, capacity and cubic capacity Manufacturing date and validity of quality Lot number Location number destination Customer's account code Customer's order number.
Carton numbers are indicated on the corrugated cardboard box that contain the mixed products.

Code 39 This is one of the oldest barcodes around and is a common symbology found in electronics, healthcare, and government.
Code Derived from the ASCII character set , a-z, A-Z, and some special characters , this compact barcode is used extensively in packaging and shipping applications worldwide. Interleaved 2 of 5 Commonly found in warehouse, distribution, and manufacturing, Code I 2 of 5 is a numeric-only barcode used to encode pairs of numbers.
Universal Product Codes UPC Found on nearly every retail product, these barcodes were originally created for grocery stores to provide quick receipt printing and inventory tracking. International Article Number EAN Considered a superset of the UPC, these barcodes are used specifically by booksellers, libraries, universities and wholesalers for book traceability. Data Matrix This has become one the most common 2D barcodes. Sign Up for Email Updates.
