What is the format of MSI barcode?

The MSI barcode, or Modified Plessey, is a continuous, variable-length symbology that encodes numeric digits (0–9). It consists of a start pattern, data digits, an optional check digit, and a stop pattern. Each digit is represented by a specific pattern of bars and spaces for consistent scanning.

Digits are represented using unique bar-and-space patterns, with optional check digits enhancing error detection. The barcode’s length depends on the number of digits encoded, which can vary based on specific application requirements.

MSI barcodes are commonly used for shelf labelling, inventory management, and warehouse operations. Modern scanners generally support MSI barcodes but may require configuration in the scanner’s settings to enable compatibility.

What type of barcode is MSI?

The MSI barcode, also known as Modified Plessey, is a linear, continuous symbology that encodes only numeric digits (0–9). Developed by the MSI Data Corporation, it is primarily used for inventory control, marking storage containers, and labelling shelves in warehouse environments.

Each digit in an MSI barcode is represented by a unique pattern of bars and spaces, following specific encoding rules. The barcode structure includes a start pattern, the data digits, an optional check digit for error detection, and a stop pattern. Applications typically implement a fixed-length code for standardisation.

While MSI barcodes are effective for certain applications, their compatibility with modern barcode scanners depends on proper configuration. Ensure your equipment supports this symbology before implementation.

What Is the Ideal Size for an MSI Code Barcode?

Character Limit of MSI Code Barcode Generator

The ideal size of an MSI barcode depends on its application, scanning distance, and printing requirements. Key considerations include:

  • Bar Width (X Dimension): The narrowest bar should be at least 0.0075 inches (0.19 mm) to ensure consistent readability.

  • Barcode Height: Typically ranges between 0.5 and 1.5 inches (1.27 to 3.81 cm), adjusted to suit the scanner’s capabilities.

  • Quiet Zone: A minimum of 0.25 inches (6.35 mm) of blank space is required on both sides to ensure accurate scanning.

  • Data Length: The length of the barcode varies depending on the numeric data to be encoded and the specific application requirements.

MSI barcodes are generally larger than other 1D barcodes, such as Code 128, when encoding the same data. This can make them less suitable for space-constrained environments. Properly balancing these factors ensures efficient scanning and smooth integration into your workflow.

How is the Checksum Calculated for MSI Code Barcodes?

Checksum Calculated for MSI Code Barcode Generator

The MSI (Modified Plessey) barcode symbology employs various checksum calculation methods to ensure data integrity during scanning. The most common methods include Modulo 10 (Mod 10), Modulo 11 (Mod 11), and combinations like Mod 1010 and Mod 1110.

Mod 10 Checksum Calculation:

  1. Assign Weights: Starting from the rightmost digit, assign alternating weights of 2 and 1 to each digit.

  2. Multiply and Sum: Multiply each digit by its assigned weight. If the product is a two-digit number, sum the individual digits to obtain a single-digit result.

  3. Total Sum: Sum all the single-digit results from step 2.

  4. Calculate Checksum: Determine the difference between the total sum and the next higher multiple of 10. This difference is the Mod 10 checksum digit.

Example:

For the number 1234567:

  • Weights: 1 (×2), 2 (×1), 3 (×2), 4 (×1), 5 (×2), 6 (×1), 7 (×2)

  • Products: 2, 2, 6, 4, 10, 6, 14

  • Single-Digit Results: 2, 2, 6, 4, 1+0=1, 6, 1+4=5

  • Total Sum: 2 + 2 + 6 + 4 + 1 + 6 + 5 = 26

  • Checksum: Next multiple of 10 is 30; 30 – 26 = 4

Thus, the Mod 10 checksum digit is 4, and the encoded number becomes 12345674.

Mod 11 Checksum Calculation:

  1. Assign Weights: Starting from the rightmost digit, assign weights in a repeating sequence from 2 to 7.

  2. Multiply and Sum: Multiply each digit by its assigned weight and sum the results.

  3. Calculate Checksum: Compute the remainder of the total sum divided by 11 (i.e., sum modulo 11). The checksum digit is 11 minus this remainder.

Example:

For the number 1234567:

  • Weights: 2, 3, 4, 5, 6, 7, 2

  • Products: 2×7=14, 3×6=18, 4×5=20, 5×4=20, 6×3=18, 7×2=14, 2×1=2

  • Total Sum: 14 + 18 + 20 + 20 + 18 + 14 + 2 = 106

  • Checksum: 106 modulo 11 = 7; 11 – 7 = 4

Therefore, the Mod 11 checksum digit is 4, and the encoded number becomes 12345674.

Mod 1010 and Mod 1110 Checksum Calculations:

These methods involve calculating two checksum digits:

  • Mod 1010: Compute the first Mod 10 checksum for the original number, append it, then calculate a second Mod 10 checksum for the new number.

  • Mod 1110: Compute a Mod 11 checksum for the original number, append it, then calculate a Mod 10 checksum for the new number.

These additional checks enhance error detection capabilities.

Implementing the appropriate checksum method is crucial for ensuring the accuracy and reliability of MSI barcodes in various applications.

What is the Character Limit of Your MSI Code Barcode Composite Generator?

Character Limit of MSI Code Barcode Generator

The MSI barcode symbology is designed to encode numeric digits (0-9) and does not inherently impose a character limit; its length is variable and can be adjusted based on specific application requirements.

However, practical considerations such as print quality, scanner capabilities, and the physical space available for the barcode should guide the optimal length. Longer barcodes may become challenging to scan accurately, especially if the printing resolution is insufficient or if the barcode exceeds the scanner’s field of view. Therefore, it’s advisable to keep the barcode length within reasonable limits to ensure reliable scanning and operational efficiency.

Why Choose a MSI Code Barcode for Your Inventory?

Choosing an MSI Code barcode for your inventory system offers several advantages:

  • Numeric Data Encoding: MSI barcodes are designed to encode numeric data efficiently, making them ideal for inventory systems that primarily use numerical identifiers.

  • Variable Length: MSI barcodes can encode a variable number of characters, providing flexibility for different inventory items and allowing for the encoding of longer numerical sequences without requiring additional space.

  • Checksum Validation: The inclusion of a checksum digit enhances data accuracy by verifying the integrity of the scanned data, reducing errors caused by misreads or incorrect data entry.

  • Cost-Effective Implementation: MSI barcodes can be easily printed using standard printers and do not require specialized printing equipment, making them a cost-effective option for businesses looking for a reliable barcode solution.

  • Ease of Printing and Reading: MSI barcodes can be easily printed on various materials and read using standard barcode scanners, facilitating quick scanning and reducing checkout times in inventory management processes.

However, it’s important to consider certain limitations:

  • Limited Character Set: MSI barcodes can only encode numeric characters (digits 0-9), which may not be suitable for applications requiring alphanumeric or special character encoding.

  • Lack of Self-Checking: MSI is not a self-checking symbology, meaning it relies on optional check digits for error detection, which may not be as robust as self-checking barcode types.

  • Scanner Compatibility: Some modern barcode scanners and applications may not recognize MSI barcodes, so it’s crucial to ensure compatibility with your scanning equipment before implementation.

MSI Code barcodes offer simplicity, flexibility, and cost-effectiveness for inventory management systems that primarily use numeric data. However, it’s essential to assess your specific requirements and ensure compatibility with your existing systems and equipment.
