QR code inventory management: how to set it up for parts and equipment
Updated · Reviewed by Israel Margulies, founder and CEO of High Point GPS
QR code inventory management means putting a scannable label on each machine, tool or parts bin, so anyone with a phone camera can pull up its record and log what happened: a count, a check-out, a part issued to a job. The label carries a short ID or web link, and the software holds everything else. Setup comes down to clean records, the right label for each surface and a defined action for every scan.
How QR code inventory works
A QR code is a two-dimensional barcode defined by the international standard ISO/IEC 18004. Each label encodes a small piece of text, usually an asset tag, a part number or a URL that opens the item’s record. When someone scans it, the software looks up the record and offers the actions that make sense for that item.
Keep the encoded text short. Denso Wave, which created the QR code, explains that symbols run from Version 1 (21 by 21 modules) to Version 40 (177 by 177 modules), and more data needs more modules. A short ID makes a coarser pattern that scans faster from farther away and survives more dirt. Putting the description, location or stock count into the code is a mistake anyway, because the label can’t update when the record does.
QR codes, barcodes and RFID compared
People searching for barcode asset tracking or an RFID asset tracking system are usually choosing between three ways to identify an item. All three only carry an ID; the difference is how you read it.
- 1D barcodes: the striped codes on parts boxes. Cheap and familiar, and a lot of supplier packaging already has one, but they hold little data and get hard to read once the label is scratched or curved around a pipe.
- QR codes: readable with a phone camera from any angle, and built with error correction. Denso Wave lists four levels (L, M, Q, H); M restores about 15% of the data and is the common choice, while Q or H suit dirty environments like a shop or yard.
- Passive UHF RFID (RAIN RFID): tags with no battery, powered by the reader’s radio signal. GS1 says they can be read at distances well over 10 meters without line of sight, so a portal can count tagged tools as a truck leaves the yard. You need dedicated readers, which phones don’t have, plus a tag on every item.
What to label, and what not to
Label what you need to find, check or charge to a job. That means every machine and vehicle, attachments that move between machines, tools worth chasing when they go missing, and parts bins or shelf locations.
For parts, label the bin, not each part. A shelf location label lets a technician scan to see what should be there, count it and issue from it. Filters and belts usually arrive in boxes with the supplier’s barcode, and labeling each cheap part one by one costs more time than it saves. Skip consumables you expense in bulk, such as rags, zip ties and shop towels.
Setting it up step by step
Plan a QR rollout like any data project: the labels are the last step. Most of the work is getting the list of machines, tools and locations right before anything gets printed.
- Clean the list first: one record per machine or part, with no duplicates under different names. Fix naming before you print, because changing an ID later means relabeling every item that carries it.
- Decide the ID format, such as the asset tag for machines and the bin code for locations. Keep it short and never reuse an ID.
- Choose the label stock for the surface: polyester or vinyl with a laminate for shop and outdoor use, metal tags for machines that see pressure washing, heat or abrasion.
- Print a test batch and scan each label with the phones your team carries, in the light where they’ll use them.
- Pick a fixed spot per machine type, such as the operator’s door frame or the left side of the boom, so nobody hunts for it.
- Start with one yard or one parts room, run it for a few weeks, then roll out.
- Walk the yard once a quarter to replace labels that are faded, peeling or painted over.
Make every scan change a record
Plan each scan to do something you’d otherwise write on paper: a part comes off stock and onto a work order, a count posts with its variance, a tool checks out to a person and a job, an operator submits a daily check, a driver reports a problem with a photo.
Decide which actions each label offers and who may do them. A technician scanning a bin should be able to issue and count. A visitor scanning a machine might only report a problem. When you map scans to actions this way, people use them, because each scan replaces a step they already do.
Running counts and audits with QR labels
Cycle counting is where labels pay back fastest in a parts room. Instead of closing the room for a full count, you count a few locations each week: scan the bin, count what’s there, enter the number and let the system post the difference. Count fast movers and expensive parts more often than slow, cheap ones.
For equipment and tools, run a yard audit by scanning every machine you can see and comparing the list with where the system thinks things are. Machines that should be on site but didn’t get scanned are the ones to chase.
QR labels and inventory in FleetZap
FleetZap prints a QR label for every machine from the Labels page. Scanning it with any phone opens a choice: the daily pre-use check or reporting a problem with photos, with no account needed. Technicians scan the same label in the field app to open the machine’s history, open work and spare parts, log a meter reading or take the unit out of service.
Parts in FleetZap are tracked by quantity on hand, reorder point and shelf location rather than by individual part labels. Each machine lists the parts it uses, and the work order part picker shows that machine’s spares first, so issuing a part takes it off stock and costs it to the machine. Stock counts cover every part, the low ones or one location, on a phone or a printed sheet, and post the variance in units and dollars. FleetZap doesn’t check individual tools in and out to people; if you need tool check-out, run it in a separate tool crib system or keep tools as assets with their location.
Key takeaways
- If a label still scans at arm's length after a month on your dirtiest machine, order that stock for the whole fleet; if not, move to a laminated or metal tag.
- Put the label in the same spot on every machine of a type and write that spot into the operator's daily check, so a missing label gets reported.
- Count the parts behind your most expensive or fastest-moving bins every week; the rest can wait for a quarterly pass.
- Choose RFID only when you need to count many items without anyone scanning them, such as tools passing a yard gate; for everything else, phone-scanned QR is enough.

Frequently asked questions
What is QR code inventory management software?
It is inventory or asset software that prints QR labels for items and lets people scan them with a phone camera to open the record and log an action, such as a count, a check-out or a part issued to a job. The label holds only an ID or link, and the software holds the stock levels, location and history.
Is RFID better than barcodes for asset tracking?
It depends on the job. Passive UHF RFID tags can be read without line of sight and many at a time, so they suit portals that count tools leaving a yard. They need dedicated readers and cost more per tag. Barcodes and QR codes need a person to scan each item but work with a phone, so they suit checks, counts and work orders.
Do I need a special scanner for QR code inventory?
No. Current iPhones and Android phones read QR codes with the built-in camera, and inventory apps use the same camera. A dedicated scanner can still help in a busy parts room where someone scans all day, because it reads faster and survives drops, but a phone covers yard checks, counts and occasional issues.
How do you track tools with QR codes?
Give each tool worth tracking a durable QR label tied to a record with its ID, owner location and status. When someone takes it, they scan it and the system records the person and job; when it comes back, they scan it in. Run a monthly scan of the tool room and chase anything still checked out past its job.
Can you use QR codes for parts inventory?
Yes, and the simplest way is to label each bin or shelf location instead of each part. Scanning the bin shows what should be there and lets a technician issue a part to a work order or enter a count. Supplier part boxes usually already carry a barcode, so labeling individual parts rarely saves time.
