Change the color, size, or shape of the last digit of the JAN code so that it's immediately recognizable.
公開日： 更新日：During the manufacturing, packaging, shipping, and display stages, it is essential to prevent product mix-ups.
In such cases, checking the last four digits of the JAN code is a common practice.
How about a proposal to help staff make quick decisions on-site? For the last four digits, assign a unique color to each number (e.g., 0 is red, 1 is orange), and for the final checksum, increase the font size of the digit itself, so mix-ups can be identified instantly.
Current Costs
Based on the following assumptions, approximately 9 million yen in costs are incurred annually.
- 5 inexperienced workers per day
- Average of 30 minutes per shift spent scrutinizing barcodes
- Hourly labor cost, etc. of 1,500 yen
- 240 operating days per year
- 10 business sites
Production Flow
- Assign colors, sizes, or font shapes to the numbers. Color might be suitable for color printing, while font shape might be better for black and white.
- Change the design of the last four digits when designing package and shipping materials.
- The last digit could have its size further altered (as a discrepancy in the last digit definitively indicates a mix-up).
- Verify if on-site staff can make instant judgments.
- Reflect the changes in the final design.
