X21L
The X21L is the embedded long module of the X series — the long-form embedded 2D window for a tall cabinet face, a screen-adjacent slot, or the column-style fascia where the short module leaves dead space.

The self-checkout column's dead meter is a scan maker.
Self-serve checkout columns spare exactly one narrow band of the fascia for scanning — above the bagging deck, beside the screen. Short modules leave dead space and an awkward aim; the X21L's long-form geometry runs the window along the column where the customer actually places the basket:
- Along the fascia, not in its way — the long form uses the column's vertical ribbon, so the aim line follows the natural bag placement instead of fighting it.
- Customer-side reads without staff — 2D on member apps and the 1D on retail items decode at the column's own height, which is the cost-saving premise of the whole machine.
- Retailer-grade accounting — the serial command set lets the column's firmware verify each basket read itself; the free SDK demos the exact flow, and the 2-year warranty rides along with the fleet.
X21L FAQs
It is the same embedded tier with the long-form geometry — the point is fascia coverage, not a different engine; the datasheet dimensions are the honest difference.
The column's own firmware sequences item reads through the serial command set — the module's part is the window and the result; the SDK demos the per-item flow the way retailers run it.
Your firmware's retry prompt runs the show; the SDK gives the fail-state result contract, and the FAE team aligns it with your UX within 48h of the sample arrival.
