Same count.
Which slabs?
Twelve tags read does not necessarily mean the twelve expected slabs are on the rack. SlabOS compares the identities, shows unexpected and unseen pieces, and lets the operator review the count before confirming changes.
Walk a rack with an RFID reader and SlabOS takes inventory. Rack A-3 should hold 12 slabs. A Take inventory count with RFID reads 12 tags, but one slab (SL-2047) is booked to B-1 and one expected slab (SL-2112) was not seen. Review every change, confirm 12 pieces, and the one misplaced slab's location updates. Unseen stock stays in inventory.

SlabOS: Walk the rack. Count the yard.
The video has no voiceover. Everything below appears on screen, over an original instrumental score.
12 slabs on paper. Which 12 are on the rack? Rack A-3.
Walk the rack. In SlabOS scanning, choose Take inventory, the RFID scan method and rack A-3, then Start count. Use the Crew app with an RFID sled, or a paired reader.
The reader walks the aisle and the tags are read one by one, from 00 of 12 to 12 of 12. No aiming, no line of sight. Each tag is counted once, and reads are saved on the device.
Same count, different slabs. SL-2047 is on the rack, but its record says B-1: it is unexpected on this rack. SL-2112 is expected on A-3, but it was not seen.
Review every change. Also place the selected pieces on this rack. I reviewed the unseen pieces; keep them in inventory. Confirm 12 pieces.
12 confirmed. SL-2047 moves from B-1 to A-3, and its location is updated. SL-2112 was not seen, and it stays in inventory.

Notes: RFID needs a compatible reader (the Crew native app with an RFID sled, or a paired reader that sends EPCs as keyboard input), and labels are encoded and verified on an RFID-capable printer before they are activated.
Prepare the identifiers
Give each slab a readable identity.
RFID starts with encoded, verified inventory labels and compatible hardware. The walkthrough uses the Crew app with an RFID sled or a paired reader that sends tag identifiers. Confirm the reader and printer support for the shop before building a count around them.
- RFID needs compatible tags and reading hardware.
- Activation follows label encoding and verification.
- QR and barcode scanning remain distinct supported methods.
Walk the rack
Read the stock where it stands.
Choose Take inventory, select the RFID method and the rack, then start the count. Read the tags as you move through the aisle. The workflow tracks identities, so repeated reads of one tag are not extra slabs. A matched count total alone is not enough to establish that the rack holds the expected stock.
- Count each identity once.
- Keep the intended rack clear in the workflow.
- Compare observed stock with the expected list.
Review the difference
Unexpected is not missing.
The clip shows twelve reads, including one slab recorded on another rack, while an expected slab is unseen. Review those differences before confirming the count. A selected misplaced piece can be assigned to the counted rack; an unseen piece stays in inventory while the team resolves where it is.
- Review location changes before confirmation.
- Unseen stock is not automatically deleted.
- A recount can help investigate the physical discrepancy.
Use the shared record
The correction follows the slab.
Confirmed location changes belong to the inventory record used by the warehouse workflow. The office and crew can then find the slab through its recorded location and the warehouse map. Keep counting discipline, label identity and physical movement aligned so the map remains useful.
- Open the warehouse map for bay context.
- Print and scan labels through the inventory-label workflow.
- Keep Piece Labels separate for fabricated job pieces.
RFID Inventory Counts questions
Does a count delete slabs that were not seen?
No. The demonstrated workflow retains unseen inventory and asks the operator to review it.
Can any phone read RFID tags by itself?
The workflow needs compatible RFID reading hardware, such as a supported sled or paired reader.
Why can the total match while the rack is wrong?
One unexpected slab and one unseen expected slab can cancel out numerically. Identity reconciliation exposes the difference.
