2. Why the Hanex A04 Is the Smarter Choice

Traditional locks rely on keys that can be lost or duplicated. Digital locks can offer a better experience, but not all are versatile enough. The Hanex A04 combines multiple authentication methods with fast performance and a clean aesthetic—so every household member can choose the access method that suits them best.

Top Reasons to Choose Hanex A04

• Multiple unlocking methods: Fingerprint, password, RFID card, and mobile app (Bluetooth/Wi-Fi) — one lock, many ways to open.

• Lightning-fast fingerprint recognition: Unlocks in under one second for instant access.

• Flexible access control: Add, remove, or manage users (fingerprints, cards, passcodes, app users) in seconds.

• Child-safe and family-friendly: Prevent accidental access to hazardous items.

• Wireless and easy install: No complex wiring — install in minutes.

• Rechargeable battery: Long-lasting battery with USB-C charging and emergency power options.

3. Key Features Explained

3.1 Fingerprint Unlock — Security at Your Fingertips

Biometric access provides quick, secure entry without carrying anything extra. Hanex uses a high-precision fingerprint sensor:

• Recognition time: < 1 second

• Accuracy: Industry-grade matching algorithm (high FAR/FRR performance)

• Capacity: Store up to 20 fingerprints for family or office use

Fingerprint access is ideal for daily use — fast, convenient, and unique to each person.

3.2 Password (PIN) Access — Reliable Backup

The built-in keypad supports PIN codes for situations where biometric access is inconvenient (wet hands, gloves, etc.). Features include:

• Custom PIN length: Choose secure passcodes.

• Temporary PINs: Create single-use or time-limited codes for guests or service personnel.

• Lockout protection: Multiple wrong attempts trigger a cooldown period to prevent guessing.

3.3 Card (RFID) Unlock — Swipe and Go

For users who prefer a physical yet keyless token, Hanex supports RFID card access:

• Card type: Standard RFID (e.g., 125 kHz EM / 13.56 MHz options depending on SKU)

• Convenience: Tap to unlock — perfect for older family members or regular users.

• Manageable: Add or remove cards via the admin menu or mobile app.

3.4 App Unlock & Remote Management — Smart Control

Want remote control and a usage log? The Hanex A04 offers a companion mobile app (Bluetooth and optional Wi-Fi gateway) that adds smart features:

• App unlock: Unlock via phone when you’re near, or use the app to open remotely if Wi-Fi gateway is used.

• User management: Add/remove fingerprints, PINs, and cards from the app.

• Access logs: View who opened the lock and when.

• Temporary access: Generate time-bound digital keys for visitors.

• Firmware updates: Keep the lock up-to-date with security patches and features.

Note: App features may require pairing and an optional Wi-Fi gateway for full remote unlocking. Offline core functions (fingerprint, PIN, card) work without internet.

3.5 Low-Battery & Emergency Power

Smart power management prevents lockouts:

• Low-battery alert: LED and beep notifications.

• Emergency power: Use a USB power bank to supply temporary power and open the lock if the battery is depleted.

• Battery life: Long standby designed for months of normal use (depends on unlock frequency).

3.6 Sleek Minimal Design & Universal Fit

Designed to match modern interiors, the A04 uses zinc alloy and ABS materials with a slim profile that fits most drawers and cabinet doors. The package includes mounting hardware suitable for wood, MDF, and metal drawers.

6. Everyday Uses — Smart Protection, Anytime

Hanex A04 fits naturally into daily routines:

• Bedroom drawers: Secure jewelry and personal items with biometric access.

• Home office: Protect legal documents and confidential files; use app logs for accountability.

• Kitchen cabinets: Keep medicines and hazardous items locked away from children; use card or PIN for quick access.

• Kids’ rooms: Stop accidental access to sharp objects or small electronics.

7. Security & Privacy: Built to Protect

Security is about more than convenience. Hanex A04 blends hardware and software safeguards:

• Biometric security: Fingerprint data is stored locally in encrypted form — not uploaded to the cloud by default.

• Encrypted app communication: Bluetooth pairing and app data use AES encryption to prevent interception.

• Admin privileges: Only an admin fingerprint/PIN can add or remove users.

• Tamper detection: Repeated unauthorized attempts can lock the device and trigger notifications in the app (if paired).

• Fail-safe design: Physical emergency override via power bank prevents being permanently locked out.

These measures protect your privacy and ensure you remain in control of access.

8. Hanex A04 vs. Single-Mode Locks — Why Multimodal Matters

Multiple access methods mean you’re never stuck: if your phone is dead, use a fingerprint; if fingers are wet, enter the PIN; if you prefer physical tokens, tap a card.

10. Maintenance & Best Practices

Keep your Hanex A04 running perfectly with minimal effort:

• Charge regularly: Top up every 3–4 months or when low-battery alerts appear. Heavy usage shortens this interval.

• Sensor care: Wipe the fingerprint sensor gently with a microfiber cloth; avoid abrasive cleaners.

• Update users: Remove lost cards and old PINs; periodically re-register fingerprints if they become less reliable.

• Firmware: Pair with the app and apply firmware updates when available to benefit from security and performance improvements.

• Indoor use: Protect from direct water exposure—A04 is designed for indoor furniture.

11. Choosing the Right Model & Accessories

Consider the following when buying:

• App features: If you want remote unlock while away, get the Wi-Fi gateway accessory or a version with built-in Wi-Fi.

• Finish: Choose black or silver to match your furniture.

• Bulk or office purchase: Contact Hanex for multi-unit discounts and centralized management options.
