Shelf labels with a check digit
Shelf labels are printed in bulk from the web: Code 128 barcode, a two-digit check code and a direction arrow. Output goes to an A4 grid or to ZPL for a thermal printer.
In a warehouse the work is done at the shelf, but the record is kept at a desk. That distance costs the same thing every time: goods move, paper piles up, and in the evening somebody sits down and keys it all in. Until then, what the system shows lags behind what the warehouse actually holds — and every mistake made during entry surfaces hours after its cause.
The difference does not show up in a feature list. It shows up in how the same job is lived.
The waybill is checked by hand and lines are ticked off on paper.
The barcode is scanned and item and quantity are matched immediately.
A pick list is printed; who picked what becomes clear only afterwards.
The app guides step by step and every picked line is recorded.
Transfers often go unrecorded; the shelf is found from memory.
The transfer is a transaction; where the material sits is on record.
The data-entry round begins — and this is where errors come from.
There is nothing left to enter; the records were created as the work happened.
Connectivity can drop in a cold store, between high racks, or in a basement. The basket is stored on the device; lines scanned so far survive a dropped connection or the app closing. Nothing is sent to Logo without a network: the app says so, keeps the draft, and you send the same draft once the connection is back. A send whose outcome is uncertain is not repeated; its counterpart in Logo is checked first.
Reliable scanning starts with the label and ends with a mis-scan that cannot go unnoticed.

Scanning a GS1-128 case barcode resolves the item (GTIN), lot, expiry date and serial in one go.
After goods receipt, material inbound, lot creation and lot split, a label screen opens; print from the device or share as ZPL. When a case or pallet is closed, a shipping label (SSCC) is prepared.
Where there is no handheld terminal, the phone's camera reads barcodes.
Scanning the wrong item or shelf brings a sound, a vibration and a short notification together; a card under the scan field shows expected and scanned side by side and the flow stops. The screen is not covered. The alert sound plays even when the phone is on silent.
On a picking route the next stop can be read aloud. On a tablet the basket and the details open side by side; the layout follows the screen width.
All seven operation categories run from the floor:
