RFID Dispatch & Receipt Tunnel
RFID Dispatch & Receipt Tunnel
Automated GRN at the Dock
SeekSoft A-GR is AOPL's RFID IoT tunnel for automated GRN and supply chain traceability. A pallet, roll cage or carton stack passes the dock once — every RAIN RFID tag is read without line of sight, reconciled against the ASN and purchase order, and posted as a goods receipt into SAP, Oracle or your WMS before the truck leaves the bay.
The Challenges We Solve
The dock is where inventory accuracy is either protected or lost. Every error created during receipt or dispatch travels downstream into stock records, replenishment, invoicing and customer service — and costs far more to correct later than to prevent at the door.
Blind Receiving at the Dock
Cartons are counted by hand, delivery challans are matched to the PO on paper, and a single truck ties up a team for hours. Storekeepers confirm quantity but never verify what is actually inside a shrink-wrapped pallet.
Vehicle Detention & Dock Congestion
Trucks idle in the yard waiting for unloading, counting and paperwork. Detention charges, missed slot windows and overtime at the gate become a permanent line item in the logistics budget.
GRN Backlog & Invoice Mismatch
Goods physically arrive on Monday and are posted on Thursday. Three-way match breaks, vendor payments stall, GST input credit reconciliation slips, and finance closes the month on stock figures nobody trusts.
Short Supply, Shrinkage & Wrong Dispatch
Without a verified count at both ends of the journey, shortages surface weeks later during cycle counts. Wrong cartons reach the wrong customer, triggering claims, chargebacks and credit notes that erase margin.
No Serialised Traceability
Batch, expiry and serial data live in disconnected spreadsheets. When a recall, audit or customer complaint lands, nobody can reconstruct which carton went into which pallet, onto which vehicle, to which customer.
The Limits of Barcode Scanning
Barcodes demand line of sight and one scan per label. Operators skip scans under pressure, scan the same label twice, or trust the supplier's ASN blindly — research across a million-item retail sample found 69% of non-RFID orders carried data errors.
From Gate-In to Posted GRN in Five Moves
SeekSoft A-GR sits between the physical dock and your ERP. Each step below is an event the middleware records, timestamps and pushes — so the goods receipt is a by-product of the movement, not a separate clerical task.
Tag & Aggregate
RAIN RFID labels are applied at item, carton or pallet level and aggregated into an SSCC hierarchy — carton to pallet to shipment — either at your supplier's line or at your own print-and-apply station.
Gate-In & ASN Pull
The vehicle is registered at the gate and SeekSoft pulls the matching ASN, inbound delivery or purchase order from the ERP, so the tunnel knows exactly what it should see before the door opens.
One Pass Through the Tunnel
The pallet crosses the portal on a forklift, pallet truck or conveyor. Multiple antennas read every tag in the stack simultaneously, and direction sensors confirm whether the load moved in or out.
Reconcile & Flag
The read set is matched line by line against the ASN. Shortages, excess, wrong batch, expired stock and unexpected SKUs are flagged on the operator display and on the andon light stack while the vehicle is still at the bay.
Post & Trace
A clean match posts the goods receipt automatically into SAP, Oracle, Dynamics or your WMS, and writes an EPCIS event so the carton's full genealogy stays queryable for audits and recalls.
Five Technology Verticals, One Dock Automation Platform
AOPL brings all five of its practices to the dock — each engineered to remove a specific failure mode from receipt and dispatch, with a quantified return on investment.
Vertical 01
SeekSoft A-GR Dispatch & Receipt Tunnel
A UHF RAIN RFID read zone engineered for the dock — antennas, reader, direction sensing and shielding tuned to your pallet profile, product mix and door width. Every tag in a moving load is captured without line of sight, without opening shrink wrap, and without a single keystroke.
- Pallets broken down and scanned carton by carton at the dock
- Shrink-wrap opened just to count what's inside
- Inbound and outbound reads mixed up at shared doors
- Tags that won't read on metal or liquid products
Vertical 02
Edge AI for Stray Reads & Exception Handling
A dock is a hostile RF environment: adjacent lanes, metal racking, staged pallets and passing forklifts all put tags inside the field that were never on the truck. SeekSoft applies signal features and motion logic at the edge so a tag becomes a business event only when the physical movement is real.
- Tags on staged pallets or the next lane counted as received
- Short or damaged loads with no photo evidence for claims
- Exceptions handled on paper after the truck has left
- No data on which suppliers send accurate loads
Vertical 03
Cold Chain & Condition Assurance at the Door
For pharmaceuticals, food, chemicals and electronics, a correct count is only half the question — the other half is whether the goods survived the journey. Sensor-enabled RAIN tags and gateway loggers attach temperature, humidity and shock history to the same receipt event, so a compromised pallet is quarantined instead of quietly entering stock.
- Temperature-damaged goods entering stock unnoticed
- Excursions found after the GRN is already posted
- Fragile consignments with no record of shocks in transit
- Condition records missing when a regulator or customer asks
Vertical 04
Gate, Yard & Dock Door Automation
An RFID tunnel delivers its full value only when the rest of the dock keeps pace. AOPL wires the gate, weighbridge, barriers, dock levellers, andon lights and CCTV into a single sequence, so a vehicle moves from gate-in to bay to release without anyone walking the yard with a clipboard.
- Trucks queuing at the gate while details are written by hand
- Weighbridge and dock not linked to the open ASN
- Operators guessing which bay to use
- No CCTV evidence tied to each receipt or dispatch
Vertical 05
SeekSoft™ Middleware & ERP Integration
Hardware reads tags; middleware turns them into trusted business documents. SeekSoft A-GR normalises reads into EPCIS events, applies your receiving rules, and writes goods receipts, putaway tasks and dispatch confirmations into the systems your finance and planning teams already live in.
- Goods receipts keyed into SAP or Tally by hand
- RFID reads that never become ERP documents
- Remote plants with poor bandwidth losing data
- Defence and regulated sites that can't use cloud software
Deployment Scenarios & Use Cases
The same tunnel architecture is tuned differently for each environment — read zone geometry, tag choice, aggregation level and ERP posting rules all follow the operation, not a catalogue.
Manufacturing Plant Stores
Inbound raw material and bought-out components are received against the purchase order at the gate, with rejections routed to a quarantine location and consumption posted from the same tag as material moves to the line.
Distribution Centre & 3PL
High vehicle frequency, mixed SKUs and client-wise billing. Tunnel reads settle inbound quantity at the door, outbound loads are verified against the pick list, and client SLAs are evidenced with timestamped read data.
Pharma & Life Sciences
Batch, expiry and serialisation are captured with the receipt, cold-chain excursions hold the GRN for quality review, and the full carton-to-pallet genealogy supports recall and regulatory audit within minutes.
Retail & Apparel Supply Chain
Source-tagged cartons pass a tunnel at the brand's DC and again at store receipt, eliminating blind ASN acceptance, closing the shrink gap between books and shelf, and enabling accurate omni-channel stock.
Automotive & Engineering
Returnable bins, trolleys and line-side kits carry permanent on-metal tags. Receipt, dispatch and container return are logged automatically, ending the perennial argument over missing packaging assets.
Defence, PSU & Government Stores
Air-gapped deployments with on-premise servers, no external dependency, and complete stores accounting from receipt to issue — built to satisfy internal audit, CAG scrutiny and GeM procurement documentation.
