The imaging counter step of the presentation line

R49

The R49 is the imaging counter unit of the presentation scanner line — the hands-free lane window where the 2D duty begins to matter, placed one rung above the workhorse and below the imaging flagship.

Retail lane with R49 imaging counter window reading a phone app code at the till
Application · Shop checkout

The lane hit its QR share — so the counter needed imaging.

Once a store's line of several hundred daily items turns a corner — more phone coupons, more member app codes or e-receipts sail over the till each shift — the lane's 4 mil-class 1D duty is no longer the whole job. The imaging counter step of the presentation family reads its EANs with everything else:

  • One window, three code families — EAN items, phone QRs and the occasional printed DataMatrix coupon all drop on the same faces on the window; no second gun, no second read path.
  • Busy-hour consistency — the imaging-counter tuning is the full set packed into the sustained present rhythm; the QR dollar-store code that flashes by at light speed is an easy mark for this lane.
  • MOQ 1 pc for the trial lane — the lane joins without buying the whole family: MOQ 1 pc, sample in 1–3 days, and the free SDK gives the POS software what it needs to consume the stream.

R49 FAQs

Position and window: the R49 is the imaging counter tier of the presentation family; the relevant difference over the workhorse is the imaging-first lane profile that the FAE can verify against your actual code mix.

Yes — phone QRs and item EANs both hit the window; dim, screen-refresh cases are a known matter in the pass rate and are checked at the sample stage with your real screens.

HID streams keystrokes into any POS; the SDK with the RS232 routine covers custom capture logic — both free, with the FAE line to answer in 48h.
