The maximum value of 30 is difficult to read by most scanners.Ĭombo readers are devices that can read both barcode and magnetic stripe media. Normally, this value is between 5 and 15. When this is left at 0, the product will automatically adjust this setting. In the PDF417 barcode type, controls the width or height by setting the number of data columns. Characters in the sets may be viewed in the Code 128 Character Set Chart.Ĭode 39 (Code 3 of 9) is the easiest of the alpha-numeric barcode types to use and only requires start/stop characters.Ĭode 93 is a barcode symbology that creates a higher density barcode it requires two checksums to be calculated. The set of characters to be used in Code 128. It can encode all 128 characters of ASCII. These letters may be used as application identifiers to identify the type of data being encoded.Ĭode 128 is a very high-density barcode symbology. Within Codabar, the start and stop characters are A, B, C or D letters. This option is not valid for DataBar and Code 128 because their check characters include non-printable values.Ĭheck readers can read bank checks encoded with either E-13B fonts or CMC-7 fonts and have a magnetic stripe reader option.Ĭodabar is a barcode symbology used for various numeric barcoding applications including libraries, blood banks and parcels. If the “Check Character in Text” or “Add Check Digit to Text” option is true, the check digit that is encoded in the barcode will be appended to the human readable text interpretation that is displayed. The check digit for DataBar and Code 128 is required and therefore cannot be disabled. When using symbologies that do not require the check digit, the check digit may be disabled. The check digit is required for all symbologies except Code 39, Interleaved 2 of 5 and Codabar. Supported values are 0 (which disables grouping), 3, 4 and 5.Īutomatically adds the check digit to the barcode when true. When it is desired to have complete control over captions, IDAutomation suggests using a separate field.ĬCD barcode scanners or readers are durable (because there are no moving parts), low power, maintenance free scanners that read barcodes by taking a linear picture that is quickly decoded.ĭetermines the number of characters between spaces in the human readable interpretation of the barcode to make text and numbers easier to read. Using captions increases the barcode size and the space between the barcode image and the caption. When text appears in the caption property, it is displayed in the margin of the barcode. Valid values are 0-10, with common values being 5 or 6.Ī bull’s eye is the center of a target of a Maxicode barcode. The default value of zero disables this option. This is measured as a multiple of the X Dimension. Horizontal and Vertical bearer bars are commonly used in Interleaved 2 of 5 and Code 39 to ensure the scanner does not misread if the scanner aiming beam falls off the barcode before it reaches the beginning or end of the symbol. 5 inches (commonly used for GS1-128)īarcode slot readers are devices that look similar to magnetic stripe readers but have the capability to read barcodes.Ī barcode verifier is a scanning device used to verify a barcode’s tolerance and readability on the printed widths of bars and spaces, and contrast between bars and spaces. The height of the bars in the barcode, usually measured in centimeters (CM). This setting should be white or transparent to ensure the scanner can easily decode the symbol. The background color of the barcode canvas. When set to true in Code 128 Auto and 2D barcode types, the tilde character may be used to encode GS1 Application Identifiers or specific ASCII characters and several additional options are enabled.Īztec is a two-dimensional (2D) barcode type that uses square modules with a unique finder pattern in the middle of the symbol, which helps the barcode scanner determine cell locations to decode the symbol. Several of these barcode properties are also used for DataBar and 2D barcode types.Ī – b – c – d – e – f – g – h – i – j – k – l – m – n – o – p – q – r – s – t – u – v – w – x – y – zĪn Application Identifier (AI) defines the purpose of the data in the symbol and how it is to be used. The chart below explains a variety of common properties for linear barcode types.
