U28
The U28 is the family-performer 2D imager of the U series — the reference-duty 2D unit for retail ops where the label mix never stops changing and the register budget has a ceiling.

Family-class values shown — exact per-model figures in the datasheet; the FAE team verifies counter-side mixes within 48h.
The back counter passes the test nobody budgets for.
Transfers, damages, supplier returns: every store has a back counter doing the paperwork the lanes never see. It is the station where label mix changes most — scratch digital, GS1-128 supplier packing tickets, tiny COD barcodes on return slips. That is performer territory, and the U28 is the family's reference unit for it:
- The counter that reads everything twice a day — the full 2D set plus dense 1D absorbs the rotating cast of labels a transfer desk sees in a week, no app swap, no second gun.
- Returns become data, not arguments — printed COD formats and repack slips decode on the first trigger, so the desk answers vendors with numbers instead of photos.
- Performer duty, standard price line — the same MOQ 1 pc and 2-year warranty as the entry tier, with the FAE 48h line for the store's exception formats.
U28 FAQs
It is the reference-duty 2D unit: full symbology set and sustained-trigger tuning at the mid price band — the number most departments use as their standardization target.
Credit-note sticker formats are typically within the 4 mil class; one sample against your vendor's sticker print quality settles whether they are readable or a reissue case.
Pricing is by quote to your volume, MOQ 1 pc; mixing tiers in one fleet is supported and common — the FAE team structures the configuration so both behave consistently at your desks.
