Tower RFID uses fixed UHF readers mounted on towers or portals at dock doors, gates and passages to read every tagged pallet, carton or asset that moves through – automatically, without scanning. 360 Soft designs and installs the readers, antennas, sensors and middleware and connects them to your WMS or ERP so that shipments and receipts are verified in real time. Here you will find how tower RFID works, use cases, the step-by-step flow at the dock, components and software modules, a comparison with robot and drone RFID, standards, delivery models, steps, KPIs, cost drivers and risks.

How tower RFID works
Antennas on both sides of a door create a read zone. When a forklift or pallet truck passes, the reader captures all EPC tags on the load. Direction and presence sensors tell the system whether goods are going in or out, and middleware filters stray reads, groups tags into a pass event and matches them with the expected order or delivery note.
Use cases
- Shipment verification at dock doors against the picking list
- Goods receipt against the advance shipping notice (ASN)
- Movements between production, quarantine and finished-goods areas
- Returnable transport items such as cages, crates and roll containers
- Asset tracking at gates for tools, IT equipment or garments
Who it suits and which problems it solves
Tower RFID suits warehouses, 3PLs, manufacturers and retailers with high pallet or carton flows and costly shipping errors. It addresses wrong or missing items in shipments, slow manual scanning at docks, disputes with customers about delivered quantities and poor visibility of movements between zones.
What happens during a shipment: step by step
- The WMS releases the shipment and assigns a dock door.
- The forklift passes through the portal; tags are read and the direction is detected.
- Middleware compares reads with the order in real time.
- A light, screen or sound confirms a correct load or flags an exception.
- The operator resolves exceptions (wrong, missing or extra items) before the truck leaves.
- The pass event is recorded and the WMS status is updated automatically.

Standards and regulation
The EPC Gen2 air interface (aligned with ISO/IEC 18000-63) and the GS1 EPC Tag Data Standard are widely used, with SSCC encoding at pallet level and SGTIN at item level. Readers must use the UHF band and power limits permitted in the country of use (for example ETSI rules in Europe and Turkey, FCC rules in the US). Installation must also follow local electrical and workplace safety rules.
Delivery models
| Model | When it fits |
|---|---|

| Managed service | We monitor devices and handle maintenance under an SLA |
| Additional team | Our engineers support your integration or IT team |
Installation steps and typical timelines
| Step | Content | Typical duration |
|---|---|---|
| 1. Requirements analysis | Flows, documents, exception rules | 1 week |
| 2. Site survey | Doors, RF environment, cabling, network | 1 week |
| 3. Read testing | Tests with real loads and tags | 1–2 weeks |
| 4. Installation | Towers, readers, sensors, feedback devices | 1–3 weeks |

Security, data protection, NDA and IP
We work under a B2B service agreement with an NDA and IP assignment of custom software. Tower RFID mainly processes product data; where staff or vehicle data is involved, we sign a GDPR Data Processing Agreement with SCCs (or the UK IDTA) and comply with KVKK.
Selection checklist
- Have read tests been done with your real loads?
- How are false reads from neighbouring doors prevented?
- How does matching with orders and ASNs work?
- What happens during a network outage?
- Who maintains the devices, and how fast?
- Can the solution scale to other sites?
Illustrative scenario: shipment verification at the dock
Illustrative scenario – not a client case.
Situation
A 3PL receives complaints about wrong or missing cartons and spends time scanning every load manually.
Designed solution
Towers with direction sensors are installed at the busiest doors. Each pass is matched with the picking list, and a stack light stops the truck when an exception occurs. After a parallel run, the remaining doors follow.
Results to be measured in the project
- Pass read success and false positive rate
- Shipping error claims before and after
- Loading time per truck
- Exception closing time
Frequently asked questions
Are pallets read when a forklift drives through?
Yes. The read zone and antenna setup are designed for passing forklifts and pallet trucks at normal speed, and read tests confirm the result.
How are false reads prevented?
With antenna shielding, power tuning, direction and presence sensors and middleware rules that ignore staged goods and neighbouring doors.
Can it be combined with drones and robots?
Yes. Towers cover moving goods at fixed points, while robots and drones count stock on shelves and racks.
Are cartons in the middle of a pallet read?
Usually, but it depends on product, packaging and tag placement. Read tests with real loads show what is achievable and which tagging rules are needed.
How many doors should be equipped?
We usually start with the busiest or most error-prone doors as a pilot and extend once results are measured.
Do we need to remove our current barcode process?
No. RFID can run in parallel with barcodes, and many sites keep barcodes as a fallback.
Which tags should we use?
EPC Gen2 UHF tags selected for your packaging and products; special tags are used for metal or liquids.
Does it work in cold stores?
Yes, with readers and tags rated for low temperatures and suitable housings.
Can it integrate with our WMS or ERP?
Yes. We connect via APIs, middleware or file interfaces to common WMS and ERP systems, including SAP.
How fast can a pilot start?
A team can typically start within 1–2 weeks; the pilot duration depends on hardware lead times and site access.
