Barcode versus QR code versus RFID for asset tracking

Barcode or QR code, in almost every case. Most organisations verify assets once or twice a year and do not have the volume or frequency of counts that would justify RFID's much higher tag and reader cost. Start with barcode unless you have a specific bulk-reading need.

Not necessarily, Code 128 barcodes are cheaper, universally supported by the simplest scanners, and entirely sufficient when the tag only needs to carry an ID number. QR code is worth the small premium mainly on compact tags where a barcode is hard to read at an angle, or where you want to encode extra reference data.

RFID tags and readers are quotation-only because pricing depends heavily on tag type, read range and volume, but as a rule of thumb they cost several times more per tag than aluminium barcode tags, plus dedicated reader hardware that barcode scanning does not require.

Yes, but note that moving means re-tagging every asset, since RFID tags are physically different from barcode tags, you cannot simply add RFID to an existing barcode label. If there is a realistic chance you will need RFID within a couple of years, it is worth discussing now rather than after a full barcode roll-out.

Passive RFID, which is what most asset tagging uses, has a limited read range typically measured in metres, not through solid walls or from a fast-moving vehicle at distance. Longer-range or vehicle-mounted reading is possible with specific reader and tag configurations, which we quote individually.

Standard RFID tags do not perform well fixed directly to metal, because the metal detunes the tag's antenna; on-metal RFID tags are built with a spacer layer to counter this, which makes them essential for RFID tagging on metal equipment, cabinets or machinery.

For barcode and QR code, yes, most smartphone cameras with a barcode/QR app can read them, which is useful for occasional spot checks, though a dedicated scanner is faster and more reliable for a full verification exercise. RFID cannot be read by a standard smartphone camera; it requires an RFID reader.

No, barcode remains the most widely deployed identification method worldwide precisely because it is cheap, reliable and universally supported. Age of the technology is not a weakness here; it is a sign of how well proven and low-risk it is.

This works fine operationally, you simply need scanning staff equipped with both a barcode scanner and an RFID reader, or a combined device, and your register software needs to record which identification method applies to each asset. This is common where a high-turnover category like laptops gets RFID for fast bulk counting and the rest of the estate stays on barcode, keeping the RFID spend targeted at the assets where the time saving actually matters.

No. QR codes are better for smartphone scanning and storing links, but Code 128 barcodes are often faster with dedicated laser scanners and fit long, narrow tags. The right choice depends on your scanning hardware, tag size and who will do the audits.

Yes, on a sufficiently large tag. This lets warehouse teams use barcode scanners while field staff use phones. On small tags, doing both can make each code too small to scan reliably, so we usually recommend choosing one and sizing it properly.

No. Scanning a QR code reads the encoded text offline. Internet is only needed if the code contains a web link you want to open, such as an asset record. Many organisations encode only the asset number so scanning works anywhere, including remote sites.

Usually just the unique asset number, such as ICT-00123. Keeping codes short makes them smaller and faster to scan, and avoids reprinting when descriptions change. Detailed information belongs in your asset register or software, linked by that number.

Common causes are worn or scratched labels, codes printed too small, poor contrast, or a format your scanner does not support. Durable anodised aluminium and properly sized codes solve most problems. Try our free barcode generator to test sizes before ordering.

Data Matrix is a compact 2D code popular for very small items and electronics. It needs an imager-type scanner, and some phone apps read it less reliably than QR. For most organisational assets, QR codes or Code 128 barcodes are the practical defaults.

Only if you need to read many items quickly without line of sight, such as racks of IT equipment or tool stores. RFID tags and readers cost more. Many organisations start with barcodes or QR codes and add RFID for specific high-value areas later.

Yes, provided the code is large enough and has good contrast. Anodised aluminium gives a clean, matte finish that phones read well. Very shiny surfaces can cause glare, so we print codes on a contrasting background and test scans before production.
