Fingerprint or Face Recognition Lock: Which Biometric Technology Is Right for Your Home?

You’ve decided to upgrade to a digital lock — but now you’re stuck choosing between fingerprint only lock or go a notch higher with face recognition. Both are biometric, both are secure, and both are significantly smarter than a traditional key. So what’s the real difference?

The short answer: fingerprint locks deliver near-instant, reliable one-touch access, while face recognition locks offer a completely hands-free, touch-zero experience — and the latest Kaadas models like the K70SE and P30 Pro Max push face recognition to a record-breaking 0.6-second unlock speed, closing the gap entirely.

This guide breaks down both technologies in full — covering speed, accuracy, performance in Malaysian conditions, hygiene, ideal user profiles, and anti-spoofing protection — so you can make the right choice with confidence.

• Fingerprint locks: fastest one-touch access, ideal for speed-focused households with up to 100 users. • Face recognition locks: completely hands-free, hygienic, anti-spoofing — Kaadas K70SE & P30 Pro Max unlock in just 0.6 seconds. • Photos and videos cannot unlock a Kaadas face recognition lock — 3D structured light verifies a live face only. • Both technologies are significantly more secure than traditional key locks.

How Does Fingerprint Recognition Work?

A fingerprint digital lock scans the unique ridge patterns on your fingertip and compares them against securely stored user profiles. Kaadas fingerprint locks use Sweden FPC biometric sensors — a leading global standard for precision and accuracy — that read from any angle

The key Kaadas advantage over competing brands is the fingerprint scanner integrated directly into the door handle. This creates a one-step, one-touch unlock — you grip the handle and the door opens simultaneously. Most competing locks require two separate actions: scan the fingerprint sensor on the body of the lock, then push the handle. Kaadas eliminates that extra step.

Key Fingerprint Lock Features (Kaadas)

• Sweden FPC biometric sensor — reads and matches from any angle with high accuracy
• Fingerprint scanner built into the handle — one-step unlock in a single motion
• Supports up to 100 registered fingerprint profiles
• Semiconductor sensor type for fast, reliable reads
• Dual fingerprint authentication available on gate lock models (entry and exit)

How Does 3D Face Recognition Work?

Face recognition digital locks use a camera and sensor array to map the three-dimensional geometry of your face. Kaadas uses 3D structured light technology — the same depth-sensing approach used in premium smartphones — to create a precise facial map at millimetre-level accuracy.

Unlike basic 2D camera-based systems, Kaadas 3D face recognition actively rejects spoofing attempts using photos or videos. The sensor verifies that a real, three-dimensional, live face is present — not a flat image. It also adjusts for changes in appearance including glasses, makeup, accessories, or different clothing.

0.6 Seconds: What That Actually Means for Daily Life

At 0.6 seconds from detection to unlock, the Kaadas K70SE and P30 Pro Max are among the fastest face recognition locks available. To put that in context: 0.6 seconds is roughly the time it takes to blink twice. You approach the door, the Air-Go auto-sensing handle detects your presence, and the door is unlocked before you’ve even reached out to open it.

Compare this to a physical key — unlocking a keyed door typically takes 5 to 10 seconds when accounting for finding the key, inserting it, and turning it. Face recognition at 0.6 seconds is not just faster; it’s in a completely different category of convenience.

Anti-Spoofing: Why Photos and Videos Cannot Open a Kaadas Lock

A common concern about face recognition locks is whether someone could use a photograph or a video of your face to gain unauthorised access. With basic 2D camera-based locks, this is a legitimate risk. With Kaadas, it is not.

Here’s why:

• 3D structured light maps the depth geometry of your face — a flat photograph has no depth and fails the scan immediately
• The sensor actively checks for the characteristics of a live, three-dimensional human face — not a screen or printed image
• IR (infrared) sensing works alongside the visible camera, adding another layer that 2D images and screens cannot replicate
• The system has been specifically engineered to distinguish between a real face and any reproduction — a core requirement for a security device

For Malaysian homeowners concerned about privacy and security, this is a critical distinction when comparing digital lock brands.

Fingerprint vs. Face Recognition: Side-by-Side Comparison

Performance in Malaysian Conditions

Wet or Oily Fingers

Malaysia’s climate and daily routines — cooking, gardening, arriving home in heavy rain — mean wet or oily hands are common. Sweden FPC sensors in Kaadas fingerprint locks outperform standard sensors in these conditions, but face recognition locks are immune entirely since no physical contact is required.

Low-Light and Night-Time Use

Fingerprint scanners work identically in any light level. Kaadas face recognition locks use infrared sensing alongside the visible camera, allowing them to function accurately in complete darkness — particularly relevant for late-night arrivals or poorly lit entrances.

Hands Full When Arriving Home

If you regularly arrive home carrying shopping, a child, or other items, face recognition with auto-sensing is a clear winner. The K70SE’s Air-Go Auto-Sensing Handle detects your approach and begins the unlock sequence before you reach the door — the door is open and ready when your hand arrives.

Gate and Main Door: Dual Unlocking

For properties in Malaysia with both a gate and a main door, Kaadas offers Dual Unlocking models that synchronise both access points with a single biometric authentication — no need to scan twice.

Frequently Asked Questions

Q: How fast does face recognition unlock on the K70SE and P30 Pro Max?

A: Both the Kaadas K70SE and P30 Pro Max unlock in just 0.6 seconds from face detection. Combined with the auto-sensing function that detects your approach, the door can be ready to open before you reach for the handle.

Q: Can someone use a photo of my face to open a Kaadas face recognition lock?

A: No. Kaadas uses 3D structured light technology that maps the physical depth of your face. A flat photograph or video screen has no depth and will fail the scan immediately. The sensor is specifically engineered to verify a live, three-dimensional face.

Q: Which is faster — fingerprint or face recognition?

A: Kaadas fingerprint locks with handle-integrated sensors unlock in under 0.5 seconds. The K70SE and P30 Pro Max face recognition locks unlock in 0.6 seconds with auto wake-up as you approach — making the practical speed difference negligible in everyday use.

Q: Will the fingerprint scanner work if my hands are wet?

A: Sweden FPC sensors in Kaadas locks perform better than average in wet or oily conditions, but accuracy can be reduced. For households where wet hands are a frequent concern, face recognition or a dual-mode model is the more reliable choice.

Q: Are face recognition locks suitable for elderly family members?

A: Yes — and they are often the best option. Face recognition requires no fine motor skill, no specific finger angle, and works at a natural standing height. The 0.6-second auto-sensing unlock means minimal effort for users of all ages.

Q: What warranty and support comes with Kaadas locks?

A: All Kaadas locks include professional installation by certified technicians and a comprehensive 2-year warranty. An optional extension is available for the third year, with responsive after-sales support throughout.
