Why aztec code

Aztec Code is a two-dimensional 2D symbology that stores data in both rows and columns. Each row in an Aztec Code symbol contains a fixed number of black or white square modules, typically with black representing a bit value of 1 and white representing a bit value of 0.

This design differs from linear barcode symbologies, such as Code 39 and UPC , that encode data using sets of black-and-white patterns of varying widths. The mode bits between these orientation patterns comprise the mode message, which indicates the number of data layers and the number of codewords stored in the symbol.

A compact code has 1 to 4 data layers, and a full-range code has 4 to 32 data layers. Figure 2 shows the orientation patterns and mode bits comprising the mode message in the compact example from Figure 1. An Aztec Code does not require a quiet zone of white space at its perimeter because the Aztec code is scanned and decoded from the inside out. Decoding algorithms know the exact size of the symbol by reading special bits at its center rather than interpreting a quiet zone.

An Aztec Code symbol is still readable when mirrored or inverted to print white on black. Aztec Code can encode numeric, alphanumeric, and binary data. It relies on sophisticated data-compaction techniques to store a large amount of data in a smaller area than linear barcodes. An Aztec Code symbol can range in size from 15x15 modules with one layer having a data capacity of 13 digits, 12 letters, or 6 bytes, to x modules with 32 layers having a data capacity of digits, letters, or bytes.

In practice, these limits are somewhat lower. Full-range Aztec Code symbols also include a fixed reference grid along every 16th row and column to help map the data layers in larger symbols. Figure 4 shows the full-range example from Figure 1 with the reference grid indicated:. We create your component and then complete the grinding, machining, and other secondary activities necessary to achieve extremely tight tolerances.

We have been and continue to be at the forefront of high temperature injection molding, the use of materials like Torlon in manufacturing, plus plastic machining and grinding. Our team includes experts on every aspect of industrial plastic manufacturing. We specialize in metal replacement.

If it can be utilized as a metal replacement, then we will work with it. Our team uses injection molding, machining, centerless grinding, cylindrical grinding, decorative services, and more to create components for the aerospace, industrial, medical, automotive, construction, electronics, consumer products, and telecommunications industries. The materials we work with:. Company History. WBEN Certification. This usage is called "structured append. ECI protocol values have four types of interpretations:.

Aztec Code uses the Reed-Solomon algorithm for error correction. The user can specify the percentage of the data region that is to be used by error correction codewords; the recommended level which is also the default minimum is 23 percent of symbol capacity plus three codewords more. Aztec Code can contain from 1 to 32 data layers, but because there are two sizes of four-layer symbols, there is a total of 33 different symbol sizes.

The smallest is 15 x 15 modules, and the largest is x modules. The barcodes are always square. There is no limit on module size. Download the Free Edition of BarTender barcode software now.

Symbol Structure The symbol comprises the following elements: Finder pattern : A square bull's-eye structure in the center that consists of alternating black and white square rings that are one module wide and a center square that is one module wide and high.

The two types of Aztec Code symbols are as follows: Compact : A compact Aztec Code symbol has two white and two black finder pattern rings in addition to the center square , one to four data layers, and no reference grid.

Because the barcodes are read from the inside out, no quiet zone is required. ECI protocol values have four types of interpretations: Identifiers of international character sets code pages Control information for structured append in unbuffered mode General-purpose, such as for encryption or compaction User-defined information.
