For most small and mid-sized businesses in Saudi Arabia, a QR code label is the practical choice for asset tracking. Any smartphone camera can read it, it costs little to print, and it can open a page for that exact asset. A barcode works if you already own scanners and only need an ID number. RFID pays off when you must count hundreds of items quickly without pointing at each one, and you can budget for readers and special tags.
How each tag works
Barcodes
A 1D barcode stores a short number or code as bars of different widths. A scanner, or a phone with a scanning app, reads it along a line, so the label must be visible and fairly flat. It holds an ID and nothing more. Everything else about the asset lives in your software.
Barcodes are cheap and widely understood. The standards body GS1 even defines an identifier for individual assets, the Global Individual Asset Identifier (GIAI), which can be carried in barcodes and RFID tags (GS1 Australia).
QR codes
A QR code is a 2D square that stores data both across and down. Denso Wave, the company that created it, notes that it can be read from any direction and can restore its data when part of the code is smeared or damaged (Denso Wave). You choose how much damage it tolerates: Level M (15%) is the most common setting, and Levels Q or H are recommended where codes may get dirty (Denso Wave), such as kitchens and workshops.
The practical advantage is that a QR code can hold a web address. Point a phone camera at it and it opens a page for that asset: a fault report form, the maintenance history or the custody record. Occasional users need no scanner and no app.
RFID
An RFID tag holds a chip and an antenna and is read by radio. No line of sight is needed, and one reader can capture many tags in a single sweep. Passive tags have no battery and start at around $0.09 each. Active tags carry a battery, cost roughly $5 and up, and usually last 3 to 5 years (Redbeam).
The bigger costs sit elsewhere. Handheld UHF readers such as Zebra’s TC22R and MC3330xR were listed at about $1,500 and $3,400 (InvGate). Metal also reflects and absorbs the radio signal, so laptops, fridges and AC cabinets need on-metal tags, which cost several times more than standard ones (InvGate).
Barcode vs QR code vs RFID at a glance
| Barcode (1D) | QR code | RFID (passive UHF) | |
|---|---|---|---|
| Read by | Scanner or scanning app | Phone camera or scanner | RFID reader |
| Needs line of sight | Yes | Yes | No |
| Reads many at once | No | No | Yes |
| Tag cost | A printed label | A printed label | From about $0.09; on-metal tags cost several times more (Redbeam, InvGate) |
| Equipment | Scanner, or phones with an app | Phones you already have | Handheld reader, about $1,500 to $3,400 (InvGate) |
| Tolerates damage | Less than a QR code | Yes, by design | Fails if the chip or antenna is damaged |
| On metal | Fine | Fine | Needs special on-metal tags |
| Best for | Warehouses that already scan | Equipment staff report faults on; mixed assets | Large, frequent counts: IT stores, tool rooms |
Durability: heat, kitchens and outdoor units
Saudi summers are hard on labels. The National Center for Meteorology recorded 51.3°C at Al-Ahsa in July 2024 and 52°C in Jeddah in June 2010 (Okaz). Rooftop condensers, generator enclosures and parking-lot equipment sit in that sun all day.
Three things decide whether a label survives:
- The print method. Direct thermal labels, printed without a ribbon, fade with heat, sunlight and abrasion. Thermal transfer printing, which uses a ribbon, is the usual choice for asset tags (IDMart).
- The material. Polyester labels resist heat, tearing and abrasion, and some are rated up to 303°F, about 150°C (Wasp Barcode). Anodized aluminum is the most durable choice for long outdoor use (Wasp Barcode). Camcode says its photo-anodized Metalphoto tags remain scannable after 20 or more years (Camcode).
- The adhesive. Temperature swings, humidity and rain can loosen adhesive (Camcode). Clean the surface with alcohol, let it dry, and press firmly.
In a restaurant kitchen, grease and cleaning chemicals matter as much as heat. Use laminated polyester, keep labels out of the area that gets scrubbed every night, and print the QR code at a higher error-correction level so a smear does not stop the scan.
Label materials and sizes
| Material | Use it for | Avoid it for |
|---|---|---|
| Paper or direct thermal | Temporary labels, boxes in storage | Anything that must last, or sits near heat or sun |
| Polyester, thermal transfer | Office furniture, IT, indoor equipment | Very hot surfaces such as oven sides |
| Tamper-evident “VOID” polyester | Laptops, monitors and routers; it shows “VOID” if peeled off (Wasp Barcode) | Assets you relabel often |
| Anodized aluminum | Outdoor AC units, generators, rooftop equipment | Very small or tightly curved items |
On size: most phones need a QR code of at least 2 × 2 cm, and the scanning distance is about ten times the code’s width (Bitly). A 2 cm code therefore scans from about 20 cm away. Leave a blank margin four modules wide on every side of the code (Denso Wave), and do not let the edge of a panel cut into it.
A 50 × 25 mm label fits a QR code, an asset number and a branch name, which suits laptops and small equipment. Larger labels make sense on rooftop units that a technician scans from a ladder.
Where to put the label
One rule covers most cases: the same spot on every asset of the same type, easy to reach with a phone, away from heat, moving parts and the manufacturer’s rating plate.
- Split AC indoor units: on the side panel or the lower edge of the casing. Not on the louvers, and not on the front cover that is lifted to clean the filter.
- Outdoor condensers: on a flat panel on the shaded side of the cabinet, away from the coil fins and the screws of the service panel. Use aluminum or a UV-rated label here.
- Commercial fridges and freezers: on the outside side panel near the door hinge, at eye level. Not on the door gasket, and not inside the cabinet where condensation forms. For a walk-in cold room, use the door frame outside.
- Laptops: on the underside next to the manufacturer’s serial number sticker, away from vents and rubber feet. Use a tamper-evident label.
- Furniture: under the desk top near the front edge, on the back of a chair below the seat, or inside the door of a cabinet. Pick one spot per type and write it down.
- Fire extinguishers: on the side or back of the cylinder, never over the operating instructions, the rating label or your contractor’s service tag. Cylinders can be swapped during servicing, so record the serial number too.
A tagging plan for a multi-branch business
- Agree on an ID format. For example,
RYD2-KIT-0042for branch, area and number, short enough to print in large type under the code. - Build the location tree first. Branch, then floor or area, then room.
- Clean your existing spreadsheet. One row per asset with name, category, serial number and location. Gaps can be filled while tagging.
- Pilot in the hardest branch. Usually the one with a kitchen. Test two or three label materials on a fridge, near the fryer and on a rooftop unit for a few weeks before buying in bulk.
- Print by branch and room. Sort each batch so the technician walks the building once. Or print blank labels, stick them on, and link each label to an asset by scanning it and taking a photo.
- Tag in a fixed walking order. Room by room, left to right. Photograph each asset and its nameplate as you go.
- Tell staff what the label is for. Print a short line next to the code, such as “Scan to report a fault”, in Arabic and English.
- Run a first count. A scan-based count straight after tagging shows what was missed or put in the wrong room.
- Give technicians spare labels. Replace damaged ones during routine visits from your preventive maintenance plan.
In Usool, each QR label carries a fixed link to its asset. You print labels on A4 sheets of 24 or on a 50 × 25 mm label printer, and blank labels are linked to an asset on first scan. Staff who scan with a normal phone camera see a fault report page with no app and no account. See the features page for the rest.
FAQ
Is a QR code better than a barcode for asset tracking?
For most businesses, yes. Phones open QR codes as links, and QR codes tolerate dirt and scratches better. Barcodes are still fine in a warehouse that already uses scanners.
Do I need RFID?
Only if you count large numbers of items often and can justify readers and on-metal tags. You can start with QR labels and add RFID later for one area, such as an IT store. Usool works with QR labels and does not support RFID readers today.
How long does a QR label last in a kitchen?
It depends on the material, print method and adhesive. Thermal transfer polyester outlasts direct thermal paper, but test your choice on a real fridge before tagging every branch.
Should the QR code hold the asset details or a link?
A link. The code stays the same while the asset’s location, custodian and history change. If the code held the data, you would reprint the label every time something changed.
