Barcode scanning without scanner hardware
Honeywell scanners cost $400 and break when dropped. The phone in your pocket reads UPC, EAN, Code 128, and QR. We measured both — here's what we found.
Dedicated barcode scanners earned their reputation when phone cameras were 3-megapixel and JavaScript decoders ran at 4 frames per second. Both numbers have changed by an order of magnitude. A modern iPhone reads a worn UPC-A from 18 inches, in 600-lux warehouse lighting, in under 200 milliseconds — which is the same envelope a Honeywell Granit holds when its battery is fresh.
What we tested
We ran 240 scans across two devices: a 2019 Honeywell CT40 ($1,200 new) and an iPhone 13 ($400 refurb). Same warehouse, same items, same operator. Phone scans averaged 0.22 seconds; the CT40 averaged 0.18 seconds. Difference: real. Practical impact at the speed an operator can pick up and put down an item: zero.
Where dedicated scanners still win
Two scenarios: continuous-scan inbound receiving where an operator scans 200 items in a stretch (the dedicated scanner's pistol grip wins on ergonomics), and freezer warehouses below 0°F where phone batteries fail. For everything else — cycle counts, picks, transfers, ad-hoc lookups — the camera-based scanner in the OneAce mobile app is the same tool you carry to lunch.
Continuous scan mode
Hold the phone over a stack of items, and OneAce reads each barcode, increments the count, plays an audible chirp, and waits for the next item without a tap. The flow matches what a pistol scanner does. The difference is your team didn't need a $400 capex line item to start.
