DPM code, also known as "Direct Parts Marking", is a special marking technology rather than a bar code standard. The DPM code can be marked directly on the surface of the parts, without the need for labels and paper carriers.

Compared with other paper barcodes or electronic labels, the advantage of the DPM code is that it can directly form graphics and text on the surface of the parts, integrate with the product itself, and become a fixed part of it, which cannot be altered and will not be lost. The DPM code will not interfere with the continued processing of the product. Products equipped with a DPM code are identifiable and traceable throughout their entire life cycle. Because of these advantages, DPM codes are widely used in manufacturing, pharmaceutical supervision, aerospace, food safety supervision and other fields for product tracking management and quality traceability.

In recent years, more and more industries have strengthened the quality traceability management of their own products, and automatic identification applications have gradually changed from 1D barcodes to 2D matrix codes. At present, the enterprise resource planning systems that are vigorously promoted in China are inseparable from QR code technology, especially DPM code technology.

Advantages of DPM code:

1. Reduce service costs and improve service quality

   As the basis for parts quality assurance, it is convenient to choose a reasonable solution

2. Improve the traceability of factory assembly products

   Provide original product data support for quality assurance, after-sales service, technical support and other links

3. Reduce production costs and improve production efficiency

    Establish the original product file to realize the fine control of the production process and product traceability

    Find bottlenecks in the production process by tracing parts through DPM codes

Optimize inventory management  

Precautions for choosing a DPM code reading handheld terminal:

For DataMatrix barcodes on metal parts, the reflective properties of metal will form a specular reflection area with particularly high brightness on the metal surface, which will affect the clarity of symbols and cause strong interference to DataMatrix recognition. Therefore, it is difficult to identify with a general barcode scanning handheld terminal, and it is only possible to use a special handheld terminal dedicated to DMP metal barcodes. XTIOT's XT8002B is a handheld terminal specially developed for DPM codes. It has strong scalability and full application coverage. It focuses on the application of DPM codes, capacitive fingerprints, HF, LF, active RFID and other functional points. And it is proud of the industry with strong functional compatibility.

XTIOT is a leading domestic R&D and manufacturer of handheld terminals. It integrates multiple functions such as PDA, data terminal, scanner and imager, and fully supports 1D and 2D barcode scanning, UHF UHF, NFC reading, and DPM reading. Reading, RFID radio frequency identification and other data collection methods. Widely used in logistics express, manufacturing, public utilities, retail, medicine, agriculture and animal husbandry and other industries.
