MicroPDF417 Scanner

What is a MicroPDF417 barcode?

MicroPDF417 codes are compact two-dimensional barcodes designed to encode moderate amounts of data in a small space. They can store up to 150 bytes of data, 250 alphanumeric characters, or 366 numeric data. The MicroPDF417 symbology is standardized in ISO/IEC 24728.

MicroPDF417’s data capacity varies based on symbol size and error correction level. The code offers 34 different symbol sizes, ranging from 1 to 4 data columns and 4 to 44 rows. Smaller versions hold around 20-30 characters, while larger ones accommodate over 200 characters.

These barcodes find applications across various industries, including in logistics for tracking shipments, in retail for product information and in healthcare for patient identification.

Structure and components

MicroPDF417 codes contain the following key components:

1. Quiet zones: Margins help identify the code’s boundaries.
2. Left Row Address Pattern (RAP): Indicates the specific row number within the barcode. It consists of 10 modules split into 3 black bars and 3 white spaces.
3. Data codewords: The core of the barcode where actual data is encoded using a series of codewords (4 bars and 4 spaces arranged within 17 modules each).
4. Right Row Address Pattern: Same as the left RAP, but on the right side of the symbol.
5. Stop bar: A single black bar located after the right RAP, serving as the final element of each row.

For codes with 3 or 4 data columns, a third RAP column is inserted in the middle.

Error correction

MicroPDF417 employs Reed-Solomon error correction across seven levels (0-6), which are automatically determined by the number of data codewords. This system can detect missing or corrupted codewords and reconstruct them up to the capacity of the chosen EC level.

Error correction in MicroPDF417 improves readability by adding redundant error correction codewords to recover lost or damaged codewords, at the cost of data capacity.

Applications of MicroPDF417 barcodes

Logistics and warehousing

MicroPDF417 barcodes facilitate tracking and management of shipments, inventory, and assets due to their compact size and high data density.

Healthcare

In the pharmaceutical industry, MicroPDF417 codes are used on medication packaging to store dosage instructions, expiration dates, and batch numbers, ensuring safety and compliance.

Retail

MicroPDF417 barcodes are ideal for encoding detailed product information, such as serial numbers, batch codes, or regulatory data, in a compact format. They are especially suited for labeling small items with limited space, like cosmetics or electronics accessories. They frequently appear as part of a GS1 Composite Code alongside a 1D barcode.

Advantages of MicroPDF417 barcodes

• Compact size and high density: They can store up to 150 bytes, 250 alphanumeric characters, or 366 numeric characters in minimal space.
• Error correction: Utilizing Reed-Solomon error correction, MicroPDF417 ensures reliable data retrieval even when parts of the barcode are damaged or obscured.
• Versatility: They are suitable for a wide range of applications, including logistics for tracking shipments, product information, and inventory management.
