Barcodes are perhaps the most enduring asset tracking technology to date.

Providing unique identification—while not necessarily giving timing or location data—barcodes are affordable, reliable, and massively scalable. Given their widespread use in numerous industries, barcode systems also have a big advantage when it comes to technology recognition and trust.

While new coding techniques like invisible or matrix barcodes (QR codes) continue to emerge, the concept has stayed largely the same since the barcode was invented: Physical items are issued a barcode that identifies the item, and a system of barcode scans log whatever checkpoint is needed.

With the simple code-and-scan configuration, barcodes have found essentially global traction in retail, manufacturing, warehousing, logistics, public transportation, and just about every other industry.

One of the biggest advantages to barcodes is the physical nature of the identifier itself. Barcodes don’t require power and can be extremely small and unobtrusive. Some are fully invisible now.

With nearly 50 years of steady use in commerce, barcoding systems are standardized across the globe to ensure that each coding is unique. Having a new barcode created for a unique product is also highly affordable.

As valuable as they are, however, barcodes aren’t the perfect asset tracking solution for every use case. Barcodes don’t inherently show location, let alone real-time status. What they do show is identification at the last recorded scan. This means scanning needs to be recorded with some form of location data to actually know where assets are—or were when scanned, at least.

To pair scans with location data, scanning is often associated with narrow choke points at key junctures. Think of scanning doorways in a library or checkout stations at a grocery store. These choke points can be expensive to install and difficult to maintain, however. Choke-point scanning limits the speed with which end users can scan assets, potentially causing backlogs and bottlenecks along the way, so some work processes are not well-suited to moving items frequently through scanning portals.

Hand-scanning barcodes is another common method. The presence of mobile scanners lends more flexibility to the process, and hand-scanners are much more affordable than portals or dedicated scanning stations. The scan is often simply done with a worker’s phone now.
