Every business strives for security and efficiency. Traditional access methods—mechanical keys and plastic cards—no longer meet the modern needs of companies. They are inconvenient, easy to lose, and can be copied or passed on to third parties.
The solution is NFC access control – a modern technology that allows employees to use a smartphone or smart device instead of a key or card.
What is NFC access control?
NFC (Near Field Communication) is a wireless communication technology for short distances (up to 10 cm). It allows:
- 📱 unlocking doors with a smartphone.
- 💳 encrypted and secure user identification.
- 🔐 use of a smart card or wristband.
VAiOS systems combine hardware (NFC readers, controllers) and management software, making them ideal for offices, business buildings, and industrial facilities.
Why is NFC better than keys and cards?
1. 🚫 No lost keys or cards
Keys and cards are easily lost, stolen, or copied. A smartphone is personal and protected with a PIN, fingerprint, or Face ID.
2. 🔐 Higher security
- NFC communication is encrypted.
- Every access is recorded in the ERP system → clearly showing who accessed the system, when, and where.
- If the phone is lost, access can be blocked remotely.
3. 📊 Centralized management
- The administrator manages access rights from a web panel.
- Option to restrict access by time (e.g., access only during working hours).
- Event history → full control and accountability.
4. ⚡ Convenience for employees
- No need to carry key rings and cards.
- Entry is quick – just tap your phone.
- Works with other systems too (elevators, turnstiles, parking).
5. 🌍 Suitable for the future
NFC is a global standard used in mobile payments and transportation. Investing in NFC access control ensures that the office is ready for smart building solutions.
Practical examples
🏢 Office building in Varna
A company with 80 employees replaces cards with NFC access:
- 100% elimination of problems with lost cards.
- Reduced costs for lock and plastic maintenance.
- Better accountability for working hours.
🏭 Industrial facility in Germany
- NFC access control integrated with ERP and BMS.
- Employees only have access to certain areas.
- Security is improved and security costs are optimized.
How much does NFC access control cost?
The price depends on the number of doors and functionality:
- Small office (1–2 doors): from BGN 2,000 to BGN 3,500.
- Medium-sized company (5–10 doors + ERP integration): BGN 7,000–15,000.
- Large building (20+ doors + turnstiles): BGN 20,000+.
⚡ The investment pays for itself through reduced costs for cards, keys, security guards, and increased security.
