Choosing asset tags feels like a technology decision, but it is really an operational one. The right tag depends on the asset's material and environment, how often you need to read it, who will do the reading, and what a missed read costs you. Pick well and scanning becomes effortless. Pick badly and labels peel, fail to read, or never get scanned at all.
This article gives you a practical decision process for barcode, QR, NFC and UHF RFID tags — and the questions to ask before you order a single label.
The four options at a glance
| Barcode (1D) | QR code (2D) | NFC | UHF RFID | |
|---|---|---|---|---|
| Read with | Scanner or phone camera | Phone camera or scanner | NFC-enabled phone | RFID handheld, sled or fixed reader |
| Line of sight needed | Yes | Yes | No (but must touch or nearly touch) | No |
| Typical read distance | Close range | Close range | A few centimetres | Up to several metres |
| Many at once | No | No | No | Yes |
| Works on metal | Yes (printed label) | Yes (printed label) | Needs on-metal tag | Needs on-metal tag |
| Relative cost per tag | Lowest | Lowest | Low | Low (labels) to moderate (on-metal/hard tags) |
| Reader cost | None (phone) to low | None (phone) | None (NFC phone) | Significant |

Question 1: How will the tag be read?
This is the most important question, and the one most often skipped.
- A person will scan it during a task they already do (check-out, inspection, audit): barcode, QR or NFC is enough.
- Nobody will stop to scan it, but you need to know when it moves: you need UHF RFID with fixed readers at the right doorways.
- You need to count hundreds or thousands of items in one place: UHF RFID with a handheld reader will be much faster than one-by-one scanning.
Question 2: What is the asset made of, and where does it live?
- Metal surfaces (tools, machines, servers, vehicles): printed QR and barcode labels work fine; NFC and RFID need tags specifically designed for metal. See on-metal RFID: what to know.
- Outdoors or harsh environments: choose UV-resistant, chemical-resistant materials — laminated polyester, anodized aluminium, or encapsulated hard tags.
- Frequently cleaned or sterilized (healthcare, food): check that the tag and adhesive survive the cleaning chemicals and temperatures.
- Curved or small surfaces: flexible labels or small tags with appropriate adhesive, or a tie-on tag.
Question 3: What is the tag worth relative to the asset?
A useful rule: the tag and the effort of reading it should be proportionate to the asset's value and risk. A $30 chair does not need a $5 on-metal RFID tag. A $15,000 instrument that walks between sites may well justify one — plus a portal reader at the store door.
Question 4: Who will do the reading, and with what?
- If your people already carry smartphones, QR and NFC have essentially zero reader cost.
- Dedicated barcode scanners are fast and durable for high-volume counters.
- UHF RFID needs dedicated hardware: handheld readers or phone sleds for walking audits, and fixed readers plus antennas for portals. Budget for installation and a site survey.
A simple decision framework
Work through these in order, per asset category:
- Default to QR for general assets. Cheap, readable by any phone, and error-tolerant.
- Use barcode if you already run barcode scanners and systems that expect 1D codes.
- Choose NFC where labels get dirty or covered, for keys and small high-touch items, or for tamper-evident tagging, and where a quick tap is more natural than aiming a camera.
- Choose UHF RFID where you need bulk counting, automatic movement detection, or reads without line of sight — and where the value of the assets justifies the hardware.
- Use dual tags where it helps: many organizations put a printed QR code on the face of an RFID label, so anyone can scan it with a phone, while readers still get bulk reads.
Worked example: mixing tags at one site
Illustrative example. A regional service depot tracks 1,800 assets:
- 900 office and workshop furniture items → QR labels (scanned once a year in an audit).
- 450 hand and power tools, all metal → on-metal UHF RFID with a QR code printed on each, plus a portal reader at the tool store door.
- 300 laptops and tablets → tamper-evident QR labels, checked out to named users.
- 150 vehicle and building keys → NFC key fobs, checked out and in at the front desk.
Total: 900 + 450 + 300 + 150 = 1,800 assets, four tag types, one register. The expensive technology is concentrated on the 450 assets where movement and bulk counting matter.
Label quality checklist
Whatever technology you choose:
- Unique ID, printed in human-readable text as well as encoded.
- Durable material and adhesive matched to the surface and environment.
- Consistent placement per asset type, so people know where to look.
- A process for replacing damaged tags while keeping the same asset ID and history.
- Spare labels on site.
Tags in Asetavo
Asetavo is tag-agnostic: each asset in the register can carry QR, barcode, NFC or UHF RFID tags, and the mobile app reads all of them — UHF via an RFID sled. Tagging includes mobile commissioning, tag inventory and clone-suspected logging; you can bring your own tags or buy pre-printed, pre-programmed ones from the Tags Store. QR and barcode are available on every plan, NFC from Growth, and UHF RFID with readers and zones on Business — see pricing.
