Warehouse access control is a system that defines who may enter a warehouse or logistics centre, through which door, when and into which zone, using cards, temporary credentials and licence plate recognition, and logs every entry. A good system manages the loading dock, drivers' waiting area, high-value cage and office separately and shows who is on site at any moment.
Key takeaways
- Warehouse access control goes beyond the main gate: docks, stock floor, cage, cold rooms and offices become zones with separate permissions.
- Drivers use a booking-linked time-limited QR code or temporary card to reach only the waiting area and their own dock, never the stock floor.
- TAPA EMEA recorded 157,421 cargo crimes in 129 countries between 2022 and 2024; the cases reporting a loss value totalled €2.7 billion.
- Contractors get personal credentials, not shared cards; access is tied to contract period, shift and health and safety induction, and lapses automatically.
- Reading access events on the same timeline as WMS movements and camera footage makes stock discrepancy investigations far shorter.
Why is warehouse access control different from an office?
In an office, most of the people coming through the door are the same employees every day. A warehouse is different: at any hour you may have shift workers, forklift operators, contract handling crews, hauliers' drivers, customs or audit staff and maintenance engineers on site. Many of them visit for a few hours and never return. The work inside is changing too: with methods such as voice picking, where instructions come through a headset, staff look at shelves rather than screens and move faster around the site.
The building works differently too. Dock doors stay open for most of the day, drivers wait beside their vehicles, and the rest area is often only a few steps from the stock floor. High-value goods such as electronics, cosmetics, pharmaceuticals or spare parts usually sit in a separate cage, yet in some warehouses that cage still opens with a single physical key.
So warehouse access control is not finished when you put a turnstile at the main gate. The real work is dividing the site into zones and deciding which group of people may be in each one. We cover the basics in our guide to card access control systems and the zoning logic in zone-based access in factories.
What does an uncontrolled warehouse cost?
When warehouse security is weak, supply chain losses are not small. Figures from TAPA EMEA, the Europe, Middle East and Africa arm of the Transported Asset Protection Association, make the point clearly:
Over the three years from 2022 to 2024, the TAPA EMEA Intelligence System recorded 157,421 cargo crimes in 129 countries. Fewer than 6% of those reports stated a loss value, yet those alone added up to €2.7 billion. (IUMI, "Global cargo crime: the scale of the problem and the role of TAPA", March 2025)
In the same piece, TAPA EMEA notes that offenders may be an organised crime group, a member of the public or someone within the victim's own organisation. Insider risk is the hardest kind to prove in a warehouse when nobody knows who entered which zone.
Not every loss is theft, either. According to the US National Retail Federation's (NRF) National Retail Security Survey 2023, the average US retail shrink rate rose from 1.4% to 1.6% in FY2022, representing $112.1 billion in losses. Those are US retail figures and cannot simply be applied to Türkiye, but in any country some stock loss can arise in the warehouse, in movements nobody recorded.
In Türkiye, most freight arrives and leaves by lorry. The Ministry of Environment, Urbanisation and Climate Change's environmental indicators show that road accounted for 90.6% of domestic freight transport in 2023. That means a steady stream of unfamiliar drivers and vehicles entering a logistics centre every day, which puts driver management at the centre of warehouse security.
How do you set up warehouse access control? A six-step framework
The six-step warehouse access control framework we recommend works for a single-site business as well as a multi-site logistics operator.
- Divide the site into zones. Gatehouse, vehicle yard, drivers' rest area, loading docks, general stock floor, high-value cage, cold rooms, offices and plant rooms. For each zone, write down who may enter and when.
- Define your groups of people. Permanent warehouse staff, shift teams, contract handlers, drivers, visitors and maintenance contractors. Each group needs a different credential: a card for permanent staff, a time-limited QR code or temporary card for drivers and visitors.
- Link vehicle entry to people. Licence plate recognition (ANPR) confirms the vehicle's booking, and the driver receives a QR code or temporary card valid only for the waiting area and their own dock. We cover the vehicle side in vehicle access control systems. To combine this with your own fleet's on-road data, see our fleet management system guide.
- Tighten the critical zones. In the cage and other high-value areas, use a turnstile or single-person entry, an anti-passback rule and, where justified, a two-person rule. Match camera footage to each access event.
- Manage contractors and temporary staff separately. Tie each contractor's occupational health and safety (OHS) induction, contract period and shift to their credential so that access lapses automatically when the period ends. Our guide to contractor access and HSE compliance goes into detail.
- Write your emergency and continuity plan. During a fire or evacuation you must be able to list who is in each zone (see our emergency muster list guide), and doors must keep working when the network goes down.
The zone table below is a starting point for warehouse access control in a typical logistics centre:
| Zone | Who enters | Suggested credential | Extra control |
|---|---|---|---|
| Gatehouse and vehicle yard | All vehicles, drivers | Plate recognition + time-limited QR or temporary card | Booking check |
| Drivers' rest area | Drivers | Time-limited QR or temporary card | No access to stock floor |
| Loading docks | Warehouse staff, assigned driver | Card / temporary card | Dock and time restriction |
| General stock floor | Warehouse staff, contractors | Card | Tied to shift hours |
| High-value cage | Small number of authorised staff | Card + single-person entry | Anti-passback, camera matching |
| Offices and plant rooms | Admin staff, IT | Card | Out-of-hours alert |
The 4 most common warehouse access control mistakes
The first warehouse access control mistake we see on site is telling drivers to "wait inside": a driver wandering the stock floor is both a security risk and an accident risk. Türkiye's Occupational Health and Safety Law No. 6331 requires employers to assess workplace risks and take preventive measures, and pedestrians in busy forklift areas are a textbook example. A separate rest area, with a credential valid only there, noticeably reduces that risk.
The second mistake is handing out shared contractor cards. When five people use one card, you have records but no accountability. Each person needs their own card or a daily temporary credential.
The third mistake is keeping access data apart from stock data. When a count discrepancy appears, the first question is "who was in the cage at that time?" If access events can be read on the same timeline as your warehouse management system (WMS) movements and your centrally managed IP cameras, an investigation is far quicker.
The fourth mistake is forgetting the cold rooms. A cold room door left open too long wastes both energy and product. Reading door events alongside cold chain monitoring data also explains why a temperature excursion happened.
How Digital Bridge sets up warehouse access control
We don't start logistics projects with an off-the-shelf package; we start with how your site actually runs. This is the approach behind our logistics and transport solutions:
- Site survey and requirements analysis: We walk the site and map vehicle and pedestrian flows, dock numbers, shift patterns and caged areas. You then receive a written proposal setting out scope, phases and cost.
- Zone and rule design: We fill in the zone table for your site and write the rules for each group of people in plain language.
- Hardware: We install card access control on doors and turnstiles, licence plate recognition at vehicle gates and, where needed, barrier systems. Because the same team builds the hardware and the software, we can adapt to unusual site conditions.
- Pilot: We first run a pilot on one group of doors, such as driver entry and the cage, and refine the rules with real data.
- Integration: We connect access events to your warehouse and inventory management (WMS) software and your IP camera monitoring, and pass time and attendance records to payroll. The payroll side is covered in time and attendance payroll integration.
- Commissioning and support: We carry out the technical feasibility study for the hardware free of charge, and once the system is live we keep it running with 24/7 technical support.
If you run several warehouses, each site can be managed separately while head office gets consolidated reports; we compare the architecture options in multi-site access control.
A warehouse and logistics scenario with SmartPass
SmartPass is Digital Bridge's product that brings card access control, time and attendance, visitor reception and canteen management together in one panel; ports and logistics sites are among its listed use cases. With SmartPass, the daily flow in a logistics centre looks like this:
- When warehouse staff present their 13.56 MHz MIFARE card, the door opens, an attendance record is created and, if they are entitled, a meal is deducted. No separate attendance terminal is needed, and timesheets follow the shift plan.
- Pre-registered drivers and visitors receive a temporary card on arrival (SmartPass does not use QR codes for entry); its permissions are limited to the visit's access group and time window, it opens nothing once the visit expires, and it is handed back on exit. Cards held by a contract handling crew are refused at the first read once the contractor's agreement ends, with no need to cancel them one by one.
- People belong to access groups; the contract handling crew's group, for example, is linked to the Docks and General Stock zones with a weekly time profile covering shift hours. Every refusal is logged with its reason, such as no zone permission, outside permitted hours or an anti-passback violation.
- Gatehouse, docks, stock floor, cage and offices are defined as separate zones, and anti-passback can be switched on per zone. The dashboard shows how many staff, contractors and visitors are inside right now; an access point switched to emergency mode frees exits, closes entries and e-mails the organisation's notification recipients.
- For operators with several warehouses, each site can be opened as a separate SmartPass organisation with its own database, and authorised users switch between sites from the "My organisations" list without re-entering a password.
On data protection under KVKK, Türkiye's Personal Data Protection Law, SmartPass does not store card numbers; each number is turned into a one-way hash the moment it is read, records past their retention period lose the fields that identify a person, and every change is written to the audit log with previous and new values. These features make compliance easier, but obligations such as the privacy notice and the retention and disposal policy stay with your organisation as data controller; our data protection compliance consultancy can help there. For general visitor-side options, see our guide to QR code visitor access. To buy SmartPass, fill in the SmartPass sales form.
Your next step
The most useful input when planning warehouse access control is a simple site plan. Note your number of docks, daily vehicle arrivals, shift pattern and caged areas. In logistics, risk does not only come through the gate; our article on email fraud targeting logistics firms covers the correspondence side.
