Interleaved 2 of 5 barcode is different from other barcode types

Interleaved 2 of 5 (ITF) is a high-density linear barcode symbology that is widely used for inventory management and tracking in various industries, including warehousing, manufacturing, and retail. Compared to other barcode types, such as Code 39 and Code 128, Interleaved 2 of 5 has several unique features that make it a popular choice for certain applications. In this article, we will discuss how Interleaved 2 of 5 barcode differs from other barcode types.

  • High-Density Barcode:

    Interleaved 2 of 5 barcodes are high-density barcodes that can store a large amount of data in a small space. This makes them an ideal choice for applications where space is limited, such as on small products or in narrow label formats. In contrast, Code 39 barcodes, for example, require more space to encode the same amount of data, making them less suitable for these types of applications.

  • Limited Character Set:

    Interleaved 2 of 5 barcodes have a limited character set, meaning that they can only encode a specific range of numbers. This limitation makes them less suitable for applications that require the encoding of non-numeric data, such as text or special characters. Barcode types such as Code 128 and QR codes can encode a wider range of characters, and making them more suitable for these types of applications.

  • Pairing Format:

    Interleaved 2 of 5 barcodes use a pairing format, where each pair of digits is represented by two bars and two spaces. This pairing format results in a higher-density barcode compared to barcode types such as Code 39, which use a single-width format. The pairing format of Interleaved 2 of 5 barcodes also makes them more resistant to scanning errors caused by dirt, smudging, or other types of damage.

  • Checksum Digit:

    Interleaved 2 of 5 barcodes include a checksum digit, which is used to ensure the accuracy of the encoded data. This checksum digit is calculated using a formula that takes into account the values of each digit in the barcode. The inclusion of a checksum digit makes Interleaved 2 of 5 barcodes more reliable and reduces the risk of scanning errors caused by data entry errors or other types of human error.

  • Numeric-Only Barcode:

    Interleaved 2 of 5 barcodes are a numeric-only barcode type, meaning that they can only encode numbers. This is in contrast to barcode types such as Code 128 and QR codes, which can encode both numeric and alphanumeric data. While this limitation may seem like a disadvantage, it actually makes Interleaved 2 of 5 barcodes more efficient for certain applications, such as inventory management.

  • Fixed-Length Barcode:

    Interleaved 2 of 5 barcodes are fixed-length barcodes, meaning that they have a fixed number of characters that can be encoded. This is in contrast to barcode types such as Code 128 and QR codes, which can encode variable lengths of data. The fixed-length of Interleaved 2 of 5 barcodes makes them more efficient for applications where a fixed amount of data needs to be encoded, such as product codes or serial numbers.

In conclusion, these features make Interleaved 2 of 5 barcode an efficient and reliable choice for certain applications, such as inventory management and tracking, where only numeric data needs to be encoded in a small space.

Structure Explained of an Interleaved 2 of 5 barcode

Interleaved 2 of 5 (ITF) is a high-density linear barcode symbology that consists of a series of bars and spaces representing numeric data. It is called "Interleaved" because the bars and spaces are interleaved between two bars representing each digit. In this article, we will discuss the structure of an Interleaved 2 of 5 barcode in more detail.

Interleaved 2 of 5 Barcode Structure
  • Start Character:

    The Interleaved 2 of 5 barcode starts with a special start character, which is typically represented by a narrow bar followed by a narrow space. This start character indicates the beginning of the barcode and helps the scanning device to identify the type of barcode being read.

  • Data Characters:

    After the start character, the Interleaved 2 of 5 barcode consists of a series of data characters, each of which represents a pair of digits. Each data character is composed of two bars and two spaces, with the width of each bar or space depending on the value of the corresponding digit. Specifically, the widths of the bars and spaces are as follows:

    Bar: Two times the width of the narrowest element for odd digits (1, 3, 5, 7, 9).

    Bar: Five times the width of the narrowest element for even digits (0, 2, 4, 6, 8).

    Space: Two times the width of the narrowest element for all digits.

    For example, the pair of digits "12" would be encoded as follows: a narrow bar followed by a narrow space (the start character), a wide bar (for the digit 1), a narrow space, a narrow bar, and a wide space (for the digit 2), followed by another narrow space.

  • Checksum Digit:

    After the data characters, the Interleaved 2 of 5 barcode includes a checksum digit, which is used to ensure the accuracy of the encoded data. The checksum digit is calculated using a modulo 10 algorithm that takes into account the values of each digit in the barcode. The checksum digit is represented by a pair of bars and spaces, with the widths of the bars and spaces being determined by the value of the checksum digit.

  • Stop Character:

    Finally, the Interleaved 2 of 5 barcode ends with a stop character, which is typically represented by a wide space followed by a narrow bar. This stop character indicates the end of the barcode and helps the scanning device to distinguish between adjacent barcodes.

In summary, the Interleaved 2 of 5 barcode structure consists of a start character, a series of data characters, a checksum digit, and a stop character. The width of each bar and space in the barcode is determined by the value of the corresponding digit, with odd digits represented by bars that are two times the width of the narrowest element and even digits represented by bars that are five times the width of the narrowest element. The checksum digit is calculated using a modulo 10 algorithm and is represented by a pair of bars and spaces with widths determined by its value. The stop character indicates the end of the barcode and helps the scanning device to distinguish between adjacent barcodes.
