![]() PDF417 - These codes can store huge amounts of data up to 1.1KB. Codes have the advantage of being very robust and fast to read. QR codes are free and publicly available.ĭataMatrix Code - Popular for logistics and operations, these two-dimensional codes are tiny in size and are ideal for labeling small items such as electronic components. QR codes support numeric, alphanumeric, byte / binary codes and hieroglyphs. QR codes are two-dimensional matrix codes intended for consumers and marketing. QR code is one of the most common 2D codes. Code 128 barcodes for use in the internal supply chain can store a variety of information. Code 128 encodes both numeric and alphanumeric text. Code 39 is the simplest of the alphanumeric codes, it is designed to self-test characters and is often used internally by small businesses.Ĭode 128 is used in transport and logistics, Code 128 is a high density ordering and distribution code. Code 39, as the name suggests, can contain up to 39 characters in a barcode. There are also options such as ISBN and ISSN for more specific applications.Ĭode 39 - used in defense and automotive. The code differs from the UPC code in that the additional first digit identifies the country of origin code. The code consists of 12 numbers, and encodes a country code, company code, and product code.ĮAN is the European equivalent of UPC codes. You can found this barcode on any product. UPC is a 12-digit one-dimensional barcode used primarily in the United States for retail and consumer products. There are many different barcode symbologies for different applications. The Code 128 stop character has the same number of spaces as a regular Code 128 character, but it has one extra Product Solution Aspose.Words Product Solution Aspose.PDF Product Solution Aspose.Cells Product Solution Aspose.Email Product Solution Aspose.Slides Product Solution Aspose.Imaging Product Solution Aspose.BarCode Product Solution Aspose.Diagram Product Solution Aspose.Tasks Product Solution Aspose.OCR Product Solution Aspose.Note Product Solution Aspose.CAD Product Solution Aspose.3D Product Solution Aspose.HTML Product Solution Aspose.GIS Product Solution Aspose.ZIP Product Solution Aspose.Page Product Solution Aspose.PSD Product Solution Aspose.OMR Product Solution Aspose.SVG Product Solution Aspose.Finance Product Solution Aspose.Font Product Solution Aspose.TeX Product Solution Aspose.PUB Product Solution Aspose.Drawing Product Solution Aspose.Audio Product Solution Aspose.Video Product Solution Aspose.eBook Product Solution Two-Dimensional Symbology is CC-A or CC-B The code set identifier used depends on what was the last code set used in the barcode and which symbology is used for the two-dimensional part. This serves as a linkage flag that alerts the scanner to the presence of the two-dimensional component. When Code 128 is used as the one-dimensional component of a composite barcode the last character before the check character (see below) must also be a code set identifier. The one that will be used for a given barcode depends on what characters need to be encoded in that portion of the barcode.Ĭode 128 start characters have the same number of bars and spaces (3 each) as regular Code 128 characters. Multiple segments with different code sets can be used in a single barcode.Ĭode 128 actually has three different start characters: the start character for Code A, the start character for Code B, and the start character for Code C. It is also possible to select the manual mode where the character code (^A, ^B, ^C, or ^S) for the different modes must be entered by the user as the first character of the segment of barcode data using that code set. ![]() Therefore, 100 of the 102 characters in code set C are used to represent the 100 two-character combinations from 00 through 99.īarTender allows selection of any of these code sets or an auto mode that will determine the best mode for the data entered. This character set is numeric-only, but any one character actually represents two digits. The three character code sets can be summarized as follows:Ĭode A: The Full ASCII set, except for the 26 lower case letters.Ĭode B: The Full ASCII set, except for the 26 "control" characters.Ĭode C: Double-density numeric. Because it is possible to use any combination of the three character sets in a single barcode, Code 128 gives you the greatest possible character density when encoding data into barcode. However, once a Code 128 barcode is started, it is possible to switch between the different character sets in the middle of the barcode. The default character set in use for any Code 128 barcode is determined by the start character. ![]() This is possible because Code 128 actually contains three different sets of 102 characters. ![]() Although Code 128 can encode all 128 lower ASCII characters, the character set itself contains only 102 characters. ![]()
