A Closer Look At Fingerprint Scanners

February 20th, 2019

The future is here, at least where various things are concerned. And one area that the modern world has finally caught up to sci-fi movies is in security systems. Fingerprint scanners, for example, are now more common in Houston, TX than most people realize.

You’ll find them almost everywhere, and fingerprint scanners are being used to secure a number of things including:

  • Mobile phones
  • Company keys
  • Access doors
  • Bank vaults
  • Vehicles
  • And more

From apartment buildings to casinos to your iPhone, fingerprint scanners are the new norm. But how do they work? Learning more about them is something well worth doing, especially when living in a world that is so reliant on them.

Fingerprint Scanner Basics

Fingerprint scanners are nothing more than devices that capture the ridges and patterns on your finger. Just as fingerprinting has been used for centuries by law enforcement, your fingerprints are stored in the system databanks. Then, instead of using a key to access different areas or things, you simply scan in your fingerprint. The system processes it and compares it with what is on file. If a match is found, your identity is verified and you’ll gain access.

There are four main types of fingerprint scanners being used today in Houston, TX. These include the following.

  • Optical – The most common option, these use a light sensitive scanner to scan in a digital copy of your fingerprint. They’re more affordable than other options, but aren’t as secure and can be manipulated.
  • Ultrasonic – One of the most accurate options, these use high frequency sound waves to scan in the fingerprint, then create a 3D image. It’s technology similar to sonar, and while it’s more accurate and reliable, they’re also more expensive than other options.
  • Thermal – Thermal readers use temperature fluctuations caused by valleys and ridges in your fingerprint. They’ll scan in very accurate fingerprints, but require a controlled temperature in the room at all times.
  • Capacitive – These systems use electricity to capture the fingerprint. Every person’s body gives out a tiny electrical charge. These sensors pick up those charges and store the information as a fingerprint.

The Big Advantages Of Fingerprint Technology

Of course, plenty of homes and businesses still use the more conventional key and lock systems. There’s nothing wrong with this, but as more and more people begin to implement fingerprint technology instead, the benefits become more apparent. Some of the advantages include:

  • Fast and easy, with no need to fumble with keys
  • No risk of losing keys or having them stolen
  • Much harder to fake or duplicate than keys
  • Can’t be picked or hacked
  • Database is easy to update, modify, and review as needed.

The Right Security For You

Whether you’re securing your home, some valuables, or your business in Houston, TX and various rooms within the business, fingerprint scanning technology is an option that deserves more attention from everyone. They’re becoming more common than ever, and offer advantages that make them stand out as being the right call for your security needs. And, with today’s technology, they’re becoming more reliable and accurate than ever before.

"Steve I just wanted to thank you and your partner Ray Kindsfather for the fine work you men did installing the security cameras around my home. The quality of the pictures is excellent, the clarity in day or infrared mode is exactly what I was looking for. What good is a camera if you can't identify the person and these cameras will greatly assist the police in identifying a perpetrator. The computer side of the job is easy and fast with very little adjustment time for me in finding what I want to see. Software and hardware get A+++++ no doubt about. The Ring is equally easy to use and the quality of the camera is equally strong. The installation was clean and fast. You maintain a clean site, it’s like you were never here. You answered all my questions with pin point accuracy. Integrity suits you well. Your answers were honest and to the point. Refreshing in today’s world. All and all you and Ray make a strong team at DWS Technology LLC. I have no problem recommending you to friend or family, home or business. God bless you both with your business. I will call you for future installations. "

"Ray, in reviewing several different security cameras there were many good products, but none met my criteria of clarity and no long-term contract. Raymond, you showed me one product that caught my attention with the clarity and distance viewing that I could not get with other systems. The zoom after a few feet became distorted with the other systems but with the Alibi NVR package you demoed, we could zoom in and out with clarity which made this product stand out from all the rest. The NVR system is so simple, in fact, anyone can configure the system to suit their needs. You can monitor your home from your smartphone or tablet and having security cameras makes it a great deterrent for criminal activity. DWS Technology delivered as promised! Your installation crew worked clean and treated my home as if it was their own. Great attention to detail! I will recommend DWS Technology to anyone! Great job guys!"
