The hardware is the same in all of them. What changes is the rule you write: an ad break in grocery, a freshness clock in produce, a pick sequence in the warehouse, a market adjustment on the lot.
A 40,000-SKU store changes thousands of prices a week between the ad, vendor cost moves, and competitive matches. Every one of those is currently a person, a printer and a walk.
Perishable shrink is not really a spoilage problem. It is a timing problem. The discount that would have sold the item on Thursday morning gets applied Friday night, when nobody is going to buy it at any price.
The received date comes in from your DSD or warehouse receipt. FreshClock attaches it to every label bound to that item, so the countdown is per-lot rather than per-SKU.
Day 0You write the rule once for the category. Day 4 goes to 20% off, day 5 to 40%, day 6 pulls the item and flags it for the department manager. The tag changes itself at each step.
Day 4 → Day 6The label flips to the red channel and prints the reason: "Ripe today." "Best by tonight." A discount that explains itself converts better than a bare number, and it protects the everyday price from looking inflated.
At each stepThe markdown reaches the POS at the same moment it reaches the shelf. No override at the lane, no sticker, no argument at the register.
Same secondEvery markdown is logged with the step, the timestamp and what sold after it. You find out which rules recovered margin and which ones were discounting items that would have sold anyway.
Weekly reportA 20% markdown on day four that sells the item recovers 80% of the retail. A 50% markdown at 8pm on day six, if it sells at all, recovers 50%. If it does not sell, you recover nothing and pay to throw it away. FreshClock exists to move that decision earlier, every time, without relying on anyone remembering to walk the case.
Freezer doors are where paper tagging is worst: cold hands, condensation, adhesive that lets go, and a case you have to open to fix a price. The F-series was specified for that aisle specifically.
E-paper film and driver specified for sub-zero refresh, not just sub-zero storage.
Dust-tight and protected against water jets. Door cycles do not get inside it.
Low-temperature chemistry, because a standard coin cell loses most of its capacity in a freezer.
Update reaches the label with the case closed and the door seal intact.
Tri-color LED on the location the picker needs next. No paper pick list, no hunting.
Physical button on the label takes the confirmation where the pick actually happens.
The e-paper shows the quantity for this order, then clears when the pick is confirmed.
Your warehouse system stays in charge. OmniTag is the display and input layer at the rack.
Traditional pick-to-light means a powered bus down every rack. OT-PICK labels are battery-powered and wireless, so a location can be lit, labelled and confirmed anywhere the access points reach, including a slot you re-racked yesterday.
Price accuracy under audit, planogram compliance you can verify from the console, and stock signalling on the shelf edge for slow-moving OTC lines.
Bin-level accuracy across tens of thousands of low-velocity SKUs, plus contractor tier pricing shown alongside retail on the same label.
Window pricing and feature callouts on 7.5" and 11.6" labels, updated from your inventory system when the market adjusts, not when someone reprints the sheet.
Outdoor-rated labels with FreshClock rules tuned to plant condition rather than a sell-by date, so the markdown lands before the plant does.
Small footprint, high change rate, and thin staffing. The aisle labor a c-store saves is a larger share of its total hours than in any other format.
Meeting-room status, desk hoteling and asset tagging on the same access-point network already installed for the retail floor.
Start there. We will scope a single-department pilot with a fixed price and a defined measurement window, then expand off the numbers you actually collected.
