The four types of symbols in an Intelligent Mail barcode. The Intelligent Mail barcode is a height-modulated barcode that encodes up to 31 decimal digits of mail-piece data into 65 vertical bars. [2] The code is made up of four distinct symbols, which is why it was once referred to as the 4-State Customer Barcode.
GS1 introduced the barcode in 1974. [8] A barcode encodes a product identification number that can be scanned electronically, making it easier for products to be tracked, processed, and stored. Barcodes improve the efficiency, safety, speed and visibility of supply chains across physical and digital channels.
Python Bar Code 128 – This code appears to draw boxes one pixel wide. It appears it was modified from a short line long line bar code which would have drawn lines. The "Black boxes" should be the same size as the "White Boxes". GenCode128 – Free C# source code implementation of Code128. Almost all features are implemented, but is not 100% ...
ZBar is an open-source C barcode reading library with C++, Python, [2] Perl, and Ruby bindings. [3] [4] [5] It is also implemented on Linux and Microsoft Windows as a command-line application, [6] and as an iPhone application.
Extended Channel Interpretation (ECI) is an extension to the communication protocol that is used to transmit data from a bar code reader to a host when a bar code symbol is scanned. It enables the application software to receive additional information about the intended interpretation of the message contained within the barcode symbol and even ...
The POSTNET 11-digit barcode was the predominant postal addressing barcode in use until the Intelligent Mail barcode (also known in its early usage as OneCode Solution) [3] was introduced and implemented. The POSTNET barcode was replaced by the Intelligent Mail barcode in the fall of 2009, combining all previous Postal Service barcodes and ...

The EPC is designed as a flexible framework that can support many existing coding schemes, including many coding schemes currently in use with barcode technology. EPC identifiers currently support 7 identification keys from the GS1 system of identifiers, as well as a General Identifier and EPC identifiers that can be used for encoding supplies ...
