Other Frequently Asked Questions

Q: What is a fingerprint door lock?
A: The fingerprint door lock, which is also known as the biometric door lock, is a type or mechanism of locking a door with the use of biometrics or fingerprint scanning. It used to be a thing of science fiction before but now it is currently being used around the world on most offices, establishments and even on residential homes.
Fingerprint door locks operate by placing the required fingertip or hand and the device scans the pattern of your fingerprint to either record it or to check if it matches the record in its database. If it is a match, it will usually involve having to input another security code to make the lock open.
Q: Why are fingerprint door locks awesome to have for safety?
A: The fingerprint door lock is a great countermeasure over keyed systems as well as number coded systems because each of us have individual patterns on our fingers and palms, which can be difficult to override. Locks can be picked but the fingerprint scanner is something that is hard to pick or destroy. If you want a security system that is high-end for your office or building then consider a fingerprint scanner system for your doors, especially for fully confidential rooms.
Q: Can you add or delete users and codes with a fingerprint door lock?
A: Yes, the fingerprint door lock has an internal memory and system in which you can delete or add users, modify pass codes or re-enter your fingerprint scans. If you live in a house with many people such as tenants or helpers then you can definitely make use of this feature. Adding users is also important because fingerprint door scanners are typically used for offices and other business and work areas.
Q: How can a fingerprint scanner tell if the fingerprint is fake?
A: This all depends on the sophistication of the system as most scanners do not have much security features unlike high-end ones. Biometric scanners that are pricier can detect the conductivity of the natural human skin and other things that can tell if the fingerprint is fake or not.
Q: Should I still have a backup key in case of an emergency when I use a fingerprint door lock system?
A: Definitely yes, because a backup key is still very important in a keyless system when the power goes out, the battery runs out of power or if the system fails miserably and you can’t get in or out during an emergency. Most fingerprint door lock systems do have a backup key system in case you get in that kind of sticky situation so it is best not to discard that key at all.
Q: Can fingerprints be placed outdoors?
A: It is not recommended for outdoor use because fingerprint scanners are meant for inside doors due to their sensitivity because of the scanner system. While they are extremely secure, they should not be used outdoors due to the threat of rain, snow and other weather elements that might wear the electronics down.
Q: Is a fingerprint door lock more secure than a pin code or card system?
A: Yes, the fingerprint door lock is significantly stronger in terms of security when it is compared to the keypad systems and the card swipe systems. This is because no one else can guess or copy your own fingerprints (unless they kill you or cut your fingers off) unlike with a pin code system or a swipe card system.
Q: Why do offices use a biometric finger scanner for doors?
A: A fingerprint scanner is much more secure than keyed entries and much more convenient than digit locks where you have to remember the pass code. Most fingerprint scanners can also double as a time-in and time-out device that will replace the punch card system in an office setting, especially if the company has a centralized database that records the time of an employee.
Q: Can a fingerprint door lock be picked?
A: At the very most no, because fingerprint door locks are electronically configured so that they are impossible to pick because they are keyless. Biometric door locks can add a lot of security to your home, office, room and other places where security is a big must have. Unlike conventional door knobs, a fingerprint door lock system is both convenient and safe in the long run.
Q: Is the fingerprint door lock advisable for all homes?
A: You have to ask your locksmith to consider if your home or establishment will require a fingerprint door lock depending on the level of security. A fingerprint door lock is more advisable for larger establishments and high-end home security purposes.
Q: Will biometric scanners work even with scars or cuts?
A: Sadly, some fingerprint scanners may not be able to recognize your pattern if your hand or fingers had a scar or a deep cut. However, there are still some alternatives that can be used as a work-around, such as registering the other fingers or asking the management about your condition. In the same way, some scanners will still work depending on how they are built and designed to recognize fingerprint patterns.
Q: What are the two most common fingerprints that a biometric scanner door lock would recognize?
A: Usually, a biometric scanner or a fingerprint scanner that locks and unlocks a door will scan your index finger or your thumb. Scanning with the index finger is the most common but using the thumb can be a bit tricky. This is practically because our thumb is positioned in an awkward way to match the position of the fingerprint scanner. In fact, most phones that have a fingerprint scanner will usually require the input of your index finger or your thumb.
Q: Aside from locking doors, where else can a fingerprint scanner be used?
A: If you have a fingerprint scanner that you previously used for a door entry and want to make use of it in another way, it can be used for a time-in and time-out of an employee. Some scanners are also found on most phones due to its diversity.
Q: Can a fingerprint scanner be used at school?
A: Yes, most schools nowadays make the use of a biometric system in various ways. For instance, it is not just used for locking and unlocking doors but also for inputting attendance of a student and a time-in and time-out record for the employee of the school. Fingerprints can also be scanned by a machine to check the attendance of a student, especially for parents who are concerned if they students go to school.
Q: What should I do when my biometric fingerprint scanner door lock runs out of batteries?
A: The batteries can be replaced depending on what is required by your biometric door lock. However, if there is currently no battery around, you can use a manual key override method, which should be reviewed in your user’s manual. Different fingerprint scanners can have different methods of overriding the key manually.
Q: If my home has a deadbolt, should I replace it if I’m going to purchase a biometric lock scanner?
A: Some keyless systems will no longer require you to take off the deadbolt of your door knob and it can be easily integrated with it, which is the same for most biometric or fingerprint scanners. However, some systems do require you to replace your old deadbolt altogether so you should think twice if you want to consider a biometric lock system and consult your local locksmith for it.
Q: Does a biometric lock only use fingerprint scanning?
A: The term biometric lock may also refer to voice recognition as well as eye recognition other than the fingerprint scanning. Biometric scanners can have one of those systems or two of them, depending on the level of security that you want and need for your home or establishment.
Q: What are the different fingerprint scanning technologies available?
A: There are 4 common fingerprint scanners available in the market today. The most common is the optical reader which is the cheapest and only reads the pattern of the visual image of the fingerprint, which is not very accurate and secure. CMOS or capacitive readers use electrical current from a capacitor to generate an image from the fingerprint so it will be harder to fool because it contours your fingers.
Ultrasound readers go through your skin because of the frequency sound waves so they can read even through scars and dirt. Thermal readers use temperature to detect the shape of the fingerprint. The last two are a bit expensive, however.
Q: What rooms can you use a biometric lock on?
A: The biometric door lock is applicable for high security rooms which contain business documents, employee records, company secrets (e.g. confidential files), server and database rooms and the like.
Q: Are biometric locks durable?
A: Compared to other keyless lock types such as the keypad system, a biometric or fingerprint scanner door lock can be difficult to break down because it is usually made of sturdy materials.
