Code 39 is discrete and variable-length, and it supports 43 alphanumeric characters.

One of the most widely used barcodes, it’s often employed in military and automotive industries.

Code 128 is particularly versatile: the variable-length symbology encodes the entire ASCII character set, features two forms of error checking, and encodes more densely than Code 39 or Interleaved 2of5.Ĭode 128 is considered a “high-density” barcode, meaning that it can fit a high number of characters in a small amount of space. Rather than reading as an incorrect code, the scanner will simply read the code as a bad scan.Ī compact barcode typically used in shipping, packing, inventory management and asset tracking. The discrete barcode encodes up to 16 characters, and it can be produced using consecutive numbers without a computer.Ĭodabar is also a self-checking barcode, which means that a printing or scanning error won’t convert one of the bars on the barcode into another (incorrect) character, resulting in erroneous scans. blood banks, this symbology is particularly convenient to print. Used primarily by FedEx airbills, photo labs, and U.S. Here are some of the most popular 1D and 2D barcode types to consider for business. Try scanning your barcodes with our free demo app in the App Store. When determining the type of barcode to use, it’s important to plan ahead, as choosing the wrong type can lead to scan errors, worker inefficiency, and unnecessary costs.Īt Aila, we’ve been helping businesses create seamless experiences by replacing legacy scanning devices with ultra-versatile imaged-based scanning technology that captures data from 1D/2D codes as well as driver’s licenses, medical IDs, OCR and more - unlocking a new world of engaging experiences and high-value workflows at a fraction of the cost of expensive legacy systems.
