- Common symbologies and conventions
- The technical concepts behind encoding/decoding data into patterns of lines, spaces and widths 

The Myriad Business Benefits of Using Barcodes

While barcodes started in retail, today they power critical workflows across many key industries:

Infographics and statistics on business use cases and ROI across sectors:

- Retail & eCommerce
- Warehousing & logistics  
- Healthcare 
- Transportation
- Manufacturing

Creating Barcodes in Google Sheets

With cloud-based Google Sheets, you can generate simple one-off barcodes for personal use like tagging home inventory free of cost.

Let me show you how step-by-step:

Screenshots + step-by-step setup guide:  

- Enabling barcode fonts
- Barcode formulas 
- Tweaking styles
- Single vs. bulk generation

Now while handy, Sheets does have limitations when it comes to enterprise grade barcode systems requiring rigorous reliability and performance.

Let us look at more advanced options…

Unlocking Barcodes in Microsoft Excel

Excel provides far more customization flexibility when it comes to industrial-scale barcode generation thanks to scripts, macros, plugins and robust integrations.

Here are the typical steps to get your barcode system rolling:

Visual guide with screenshots:

- Enabling fonts  
- VLOOKUP formulation
- Customizing stylistic elements
- VBA scripting for advanced automation

Now let me share some pro power user tips…

Optimizing Barcode Workflows with VBA Scripting

While the basics will work, if you really want to take Excel barcode generation to the next level, VBA scripts are the way to go.

Here are some common use cases that can be automated:

Dynamic Value Assignment

Automatically generate serial numbers, SSCC codes etc. sequentially and assign to new items as you expand inventory.

Batch Printing

With one click rapidly print hundreds of barcode labels or tags in customized sheets by tapping into Excel‘s fast batch processing capabilities.

Scanning Workflows

Develop scripts to lookup product information from SQLite/MySQL dataset when barcode is scanned and retrieve associated metadata like descriptions, pricing, dimensions etc.

Cross-Application Integration

Sync barcode data across other LOB systems like QuickBooks, proprietary ERP/WMS apps to maintain a single source of truth.

The possibilities are truly endless for power users who master VBA automation!

Barcode Scanners – Decoding the Secret Sauce

A key component of any barcode system is the scanner used to read the encoded data.

Here is a high-level overview:

Scanner Connectivity Options

Wired Scanners

Most reliable connectivity and speeds but reduced mobility due to wires. Common ports include USB, PS/2, RS-232 serial interfaces.

Wireless Scanners

Cuts the cables offering improved mobility but potential for interference and congestion depending on surrounding environment. Popular wireless protocols used are Bluetooth and WiFi.

Smart Device Cameras

Modern machine vision algorithms can reliably decode barcodes using smartphone/tablet cameras. Convenient but performance varies greatly based on hardware specs.

In addition to the above, Enterprise grade scanners provide robust integrations with surrounding infrastructure:

  • Built-in Inventory Databases: Some come preloaded with millions of product barcode data
  • ERP/WMS Integration: Bi-directional sync ensuring barcode data is shared across the entire business software ecosystem.
  • Customized Triggers: Program routines to invoke on specific scan events like lookups, printing etc.

The Road Ahead: AI and IoT Barcodes

Barcode technology continues to rapidly evolve with new innovations leveraging:

AI-based Automated Data Capture

Machine vision powered cameras with deep learning models identify and extract information from documents and forms without need for barcodes.

IoT-Integrated Smart Barcodes

Miniaturized sensors within barcodes to monitor temperature, humidity, pressure etc. in supply chain provide dynamic real-time analytics.

Success Stories: Barcodes Powering Business

While the concepts so far might seem theoretical, barcodes today deliver real tangible business impacts as these examples demonstrate:

American Golf: Inventory Management

Situation: Periodic warehouse counts were time consuming and error-prone.

Solution: Deployed automated barcode scanning systems.

Impact: Cut hours off inventory counting allowing faster order processing.

The Home Depot: Asset Tracking

Situation: Difficulties locating equipment across hundreds of locations.

Solution: Industrial Bluetooth barcode scanners.

Impact: Rapid asset visibility reduced loses/theft saving millions.

The above are just two of many such success stories across industries. The common themes are increased efficiency, lower costs and tighter process controls.

Now let me summarize the key lessons for you…
