Fingerprint scanners make the leap from spy flicks to your smartphone

The words “biometric fingerprint scanning” are never going to fill seats or win fans. It’s a technical phrase that sounds boring, and we’ve been seeing biometric scanners in odd electronics for years now, but a company named CrucialTec has finally made fingerprint scanning a sexy feature you’re going to want in your next phone.

We caught up with CrucialTec at Mobile World Congress this week. CrucialTec is targeting the smartphone industry with its scanner, and it’s ready to be built right into a device’s home button. Imagine your iPhone’s home button could also scan your fingerprint at lightning speed. It would know if you’re its owner, but beyond even that, the possibilities are astounding.

The demo we were shown had a biometric scanner built into a home button on a custom case. At it’s most basic, CrucialTec’s fingerprint scanning adds a high level of security to locking and unlocking your phone. You slide your thumb down the home button to unlock it, and it won’t unlock unless your print matches the one you stored when you set up your phone. Swiping your thumb takes the same amount of time as drawing a simple unlock pattern on an Android phone, but its infinitely more secure. As time rolls on, we’re relying on our phones to help us perform more and more sensitive activities, like banking and paying for items, but our security usually still consists of a four-number pin or no locking mechanism at all. It’s archaic.

10 fingers, 10 features

Basic, fast fingerprint scanning is all and good, but CrucialTec’s system gets interesting with the additional security and convenience features. Usually, fingerprint scanning uses one finger, but most of us have nine other digits sitting idle. CrucialTec’s software allows you to assign a different function to each of your 10 fingers. For example, the camera could be linked to your index finger, and sliding that down the home button would unlock the phone and automatically open the camera app. Its secure nature also lends itself to quick launching apps such as Expensify, or wireless payment and online banking apps.

CrucialTec’s biometric scanner can also securely encrypt files which can only be opened using a swipe of your finger. The process is incredibly slick, as all that’s needed is to tap and hold the file you want to encrypt, then slide your finger over the home button. The file turns to a picture of a locked padlock and the original is securely locked away. You can unlock files by repeating the same process. Although this was demoed using pictures of a more adult nature, there are plenty of other (less dirty) files you might want to encrypt on your phone. With the introduction of such a simple encryption process, it may prompt us to store information we currently avoid saving.

It doesn’t hog power and is extremely accurate

Biometric scanners aren’t power hogs, so adding them to modern smartphones won’t put additional strain on the battery. We’re told that the failure rate – or how often it falsely accepts a non-user or fails to recognize your print – is miniscule. A working fingerprint scanner can benefit anyone if its integrated correctly, but with the shortcuts and file encryption, scanners like CrucialTec’s may actually be fun to use. When Apple purchased fingerprint scanner firm AuthenTec last year, its technology became an Apple exclusive. Since then, there have been rumors the next iPhone may incorporate it. The industry being what it is, this could see the tech quickly increase in popularity.

We’re told CrucialTec’s system has already been licensed by an unnamed Chinese manufacturer, and is expected to be added as a feature to a smartphone released this summer. Hopefully we’ll get to use this system sooner rather than later.

If you're looking for affordable tablet deals, it's highly recommended that you check out Amazon's Fire tablets. The latest releases of the brand's largest models are still relatively cheap, and limited-time discounts have further lowered their prices on Amazon right now. The 32GB version of the Amazon Fire HD 10 is down to $95 from $140 for savings of $45, and the 64GB version of the Amazon Fire Max 11 is down to $180 from $230 for savings of $50. You're going to have to be fast with your purchase once you've chosen which one to buy though, because these tablets may be back to their regular prices as soon as tomorrow.

The 2023 release of the Amazon Fire HD 10 retains the tablet's budget-friendly price  despite several improvements compared to its predecessor, including 25% faster performance, slightly less weight by 30 grams, and an upgraded front-facing camera from 2MP to 5MP for clearer selfies and video calls. The Amazon Fire HD 10 features a 10.1-inch Full HD touchscreen that's durable enough to withstand daily wear and tear, compatibility with Amazon's Alexa for voice commands, and decent performance for your daily tasks with its octa-core processor and 3GB of RAM. The tablet comes with 32GB of internal storage, but if you need additional space for your apps and files, you can get up to 1TB more through its microSD card slot.

The camera on this Android phone is confusing, but I love it
The back of the Tecno Camon 30 Premier.

I’m all for a lot of detail, and love to hear about the new technology that’s inside a smartphone I’m about to test, but when I have to search for an explanation of what something means, it’s not a good start. The Tecno Camon 30 Premier suffers from this problem, as it has a lot of cool camera tech that is explained in a mystifying way.

So, I thought the best thing to do was to just ignore the tech speak and find out if it takes great photos the old-fashioned way.
What's the problem?

The 5 best phones with IR blasters in 2024
The OnePlus 12's camera module.

IR blasters used to be a common component in smartphones, with big products from Samsung, OnePlus, and TCL giving users access to the cool gadget. Phones equipped with IR blasters could be used as a universal remote for your other electronics, making it easy to control your gear without the need for their default controller (which might be clunky and unintuitive to use).

Fast forward today, and attempting to find a smartphone with an IR blaster is shockingly difficult. What was once common technology is now relegated to just a handful of smartphones. You won't find any iPhones or Galaxy phones with IR blasters, but that doesn't mean you have to settle for a poorly reviewed smartphone if you're interested in the tech. You will, however, probably need to settle for either OnePlus or Xiaomi, as they're the two key players still churning out powerful smartphones equipped with IR blasters.
