How Scanflow Delivers Digital VIN Verification for Daimler at Production and QC

Daimler’s existing VIN Plate, VIN Sticker, and VIN Chassis Number verification process relies heavily on manual inspection during the Production and Quality Check stages. Operators manually verify VIN information against vehicle and MES data, making the process time-consuming and susceptible to human error. Manual documentation also creates challenges in traceability and makes it difficult to maintain consistent verification across different stages. The lack of seamless integration between the verification process and existing systems further increases the possibility of mismatches between the VIN information physically available on the truck and the corresponding MES records.

Daimler’s MES, running on Rockwell Automation, is an industrial ERP system with a master database containing all the required information for VIN plates and VIN stickers — including English, Arabic, and Spanish sticker variants. That master data holds the values that need to be engraved or printed on the respective plate or sticker, giving Scanflow’s solution a single source of truth to validate every scan against.

Daimler engaged Scanflow to digitize and automate VIN verification through an Android-based mobile application integrated with Scanflow SDKs, validating every scan directly against MES.

1. Manual VIN Verification Was Time-Consuming and Error-Prone Operators manually verified VIN information against vehicle and MES data, a process that took time and was susceptible to human error.
2. Manual Documentation Limited Traceability Verification results captured on paper made it difficult to maintain a reliable, traceable record of what was checked at each stage.
3. Inconsistent Verification Across Stages Without a standardized digital process, maintaining consistent verification across Production and Quality Check stages was difficult.
4. No Seamless Integration with MES Increased Mismatch Risk The lack of integration between the manual verification process and existing systems increased the possibility of mismatches between the VIN information physically on the truck and the corresponding MES records.

Scanflow proposed a mobile verification application to digitize and automate the VIN verification process. The operator first scans the VSN barcode from the build card to validate the truck model, then captures the VIN Plate, VIN Sticker, or VIN Chassis Number. The application extracts the required field values and compares each one individually with the corresponding data in Rockwell Automation MES. If a field matches, a green tick is displayed next to it; if it doesn’t match, a wrong/error symbol is shown, and the operator can manually edit the incorrect value on the spot. Once every value is verified, the operator presses Update MES, and the system acknowledges that the serial number has been mapped to the corresponding VIN details completing the process. 

VSN Barcode Scan 

The operator scans the VSN barcode from the build card to validate the truck model, identifying the vehicle at the start of the workflow. 

VIN Plate / Sticker / Chassis Capture 

The operator captures the VIN Plate, VIN Sticker, or VIN Chassis Number, covering both supported use cases. 

Field-by-Field MES Comparison 

The application extracts each required field from the capture and compares it individually against the corresponding value in Rockwell Automation MES’s master data — including English, Arabic, and Spanish sticker variants. 

Visual Match Indicators 

A green tick appears next to any field that matches MES data; a wrong/error symbol flags a mismatch, so the operator sees exactly which field needs attention. 

Manual Correction on Mismatch 

If a field doesn’t match, the operator can manually edit the value directly in the app before proceeding, rather than leaving the discrepancy unresolved. 

Update MES & Serial Mapping 

Once all values are verified, the operator presses Update MES. The system then acknowledges that the serial number has been mapped to the corresponding VIN details, completing the process. 

Solution Architecture 

Daimler’s Rockwell Automation MES remains the single source of truth for VIN plate and sticker specifications. The mobile application fetches the expected field values from this MES master database, performs the field-by-field comparison on the device, and pushes verified (or corrected) values back to MES through the Update MES action with no separate Scanflow centralized database in the loop. 

• System of Record — Rockwell Automation MES — an industrial ERP with VIN plate/sticker master data. 

• Master Data Coverage — English, Arabic, and Spanish VIN plate/sticker variants. 

• Capture Flow — Scan serial number → scan VIN plate/sticker → field-by-field comparison → Update MES. 

• Verification Output — Per-field match indicator (green tick / error symbol), with manual edit available on mismatch. 

• Data Storage — Rockwell Automation MES only — no separate Scanflow centralized database. 

By replacing manual VIN Plate, VIN Sticker, and VIN Chassis Number verification with a digital, MES-validated scan-and-capture workflow, Daimler gains a faster, more consistent, and more traceable verification process across Production and Quality Check stages.

Key Outcomes

• Fewer verification errors — field-level comparison against MES master data replaces a single manual judgment call. 

• Immediate error localization — green tick / error symbol indicators show operators exactly which field needs correction. 

• On-the-spot correction — operators can fix a mismatched value immediately, rather than flagging it for later rework. 

• Clean MES mapping — the Update MES action confirms the serial number is mapped to its verified VIN details, closing the loop. 

• Multi-language coverage — verification works across English, Arabic, and Spanish sticker variants using the same MES master data. 

Delivery Footprint

• Rugged handheld mobile app used at Production and Quality Check
• Daimler’s MES/backend as the system of record — no separate Scanflow centralized database

Daimler strengthens VIN verification accuracy and traceability with Scanflow, giving operators a single mobile workflow to scan, verify, and record VIN data against MES at every stage.

Daimler’s VIN verification process is no longer dependent on manual cross-checks at Production and Quality Check. Operators now scan the VSN barcode to validate the truck model, capture the VIN Plate, Sticker, or Chassis Number, and get an MES-validated result instantly — even without continuous connectivity. The result is a faster, more consistent, and fully traceable verification process across every stage and use case.
