Pharmaceutical picking and dispensing errors cost the industry $20 billion annually in recalls, fines, and lost productivity. But simple barcode scanning optimizations can dramatically reduce these mistakes—without expensive tech overhauls or a complete system rebuild.
After implementing 10 proven scanning strategies, our 12-facility distribution network achieved:
- 90% reduction in mispicks
- 40% faster scanning speeds
- 100% DSCSA serialization compliance
These outcomes were not the result of expensive AI platforms or custom hardware, but rather practical upgrades and disciplined implementation. Here’s exactly how we did it—and how your organization can replicate these results, even with limited budgets.
The 5 Most Costly Pharma Barcode Errors (And Fixes)
1. Unreadable Barcodes (23% of errors)
Fix: Use UV-resistant labels (e.g., Zebra ZT410 industrial printers)
Extra tip: Apply laminated overlays for cold chain products
Unreadable barcodes often stem from environmental degradation—humidity, sunlight, and refrigeration can all distort labels. Investing in durable printing upfront prevents downstream losses and re-labeling labor.
2. Database Mismatches (31% of errors)
Fix: Sync scans with real-time ERP validation (SAP/Oracle APIs)
Extra tip: Automatically flag non-GS1 barcodes
Disconnected data systems create blind spots. By enabling real-time validation between scanners and ERP databases, we eliminated delayed rejections and ensured every pick is traceable and verifiable.
3. Expired Product Picks (18% of errors)
Fix: Configure scanners to alert for <6-month expiry
Extra tip: Use AI routing to auto-reassign short-dated stock
This single change prevented over 300 expired units from reaching pharmacies. It also empowered our warehouse team to make decisions in real time—without manager intervention.
4. Similar-Drug Confusion (15% of errors)
Fix: Add custom color-coded barcode borders
Extra tip: Include secondary QR codes displaying drug images
In environments where dozens of products look identical, visual differentiation is key. Training time for new hires also dropped significantly after color-coding implementation.
5. Counterfeit or Diverted Products (13% of errors)
Fix: Implement blockchain verification for serialized scans
Extra tip: Cross-check DSCSA T3 data automatically
Blockchain provides a tamper-proof ledger that’s increasingly accepted by regulators and major partners. Although it requires initial integration, the long-term compliance benefits are substantial.
Result: These five adjustments alone reduced errors by 64% during Phase 1.
Five Advanced Scanning Upgrades for 2025 Compliance
1. Voice-Directed Scanning
Guides pickers with verbal prompts like “Scan shelf A7”
Result: 27% faster than handheld-only methods
Tools: Honeywell Vocollect + Zebra TC52/TC57
Voice workflows are particularly effective in high-noise or low-light environments, increasing safety and accuracy simultaneously.
2. Augmented Reality Overlays
Smart glasses display visual directions to the next pick
Result: 41% fewer location-based errors
Tools: Google Glass Enterprise + SAP EWM
3. AI-Powered Image Validation
Cameras confirm the visual match between product and label
Result: 100% match confirmation
Tools: Cognex VisionPro + OpenCV
4. Multi-Scanning Tunnels
Scans all six sides while products move on conveyors
Result: 300% higher throughput
Tools: SICK MSC800
5. Mobile Audit Trail
Each scan logs GPS, timestamp, and employee ID
Result: Fully automated DSCSA audit trail
Tools: TraceLink Mobile
Before and After: Scanning Metrics
| Metric | Pre-Implementation | Post-Implementation |
|---|---|---|
| Scans per Hour | 142 | 387 |
| Error Rate | 5.2% | 0.5% |
| FDA Audit Findings | 12 | 0 |
| Staff Training Time | 8 hours | 22 minutes |
Insight: Color-coded barcodes had the highest ROI, especially in large warehouses with high SKU overlap. They delivered an 83% drop in error rates with a minimal implementation cost.
3 Unconventional Scanning Hacks
1. The “Upside-Down” Test
If a barcode can be scanned while inverted, it may be too symmetrical—leading to higher error risks.
Solution: Rotate the barcode design by 15 degrees or add asymmetrical elements to improve scan accuracy.
2. Pallet-Layer Checksums
Encode pallet layer numbers directly into barcode data (e.g., “L3 of 5”) to provide an added layer of verification.
Benefit: Prevents misplacements caused by partial or incorrect pallet picks.
3. Blue Light Verification
Use a 585nm wavelength scanner to detect tampering or relabeling.
Recommended Tool: UVEX BlueLight Scanner, especially effective in secure chain-of-custody environments.
5 Scanning Mistakes That Invalidate DSCSA Compliance
- Using non-GS1 barcodes, which can trigger immediate FDA citations
- Allowing manual keyboard overrides, which compromises audit trails
- Operating unsecured Bluetooth scanners, exposing data to hijacking
- Failing to log temperature excursions, violating 21 CFR Part 11
- Relying on single-point scans, which miss aggregated or nested packaging units
Recommendation: Conduct monthly audits using GS1’s free Barcode Verifier to ensure ongoing compliance.
Budget vs. Premium Scanning Solutions
| Application | Budget Option | Premium Option |
|---|---|---|
| Basic Compliance | Zebra DS2208 ($600) | Honeywell 8675i ($1,900) |
| Cold Chain | Datalogic Memor 10 ($1,200) | Zebra MC9400 ($3,300) |
| Augmented Reality | Vuzix M400 ($1,800) | RealWear HMT-1 ($2,500) |
| AI-Based Validation | Cognex DataMan 150 ($2,100) | Keyence SR-1000 ($7,000) |
Optimal Mid-Range Pick: Zebra TC57 (~$1,700) — a versatile device that meets over 90% of pharmaceutical scanning needs.
