Earlier this week, Synaptics announced that it's cracked the problem of embedding fingerprint sensors into displays and is mass-producing the. Synaptics announces mass production of optical in-display fingerprint sensors. We already knew that Vivo is the company that partnered with Synaptics to launch the first smartphone in the world with a fingerprint sensor.

Unfortunately, the forums have been discontinued. All discussion has been moved to the comments Synaptics Fingerprint Sensors of our articles, so start clicking on the topics you're interested in to dive back into the conversation! How fingerprint scanners work: Technology has moved on a lot from the early days too, becoming faster and more accurate in their readings.

Synaptics Fingerprint Sensors Optical scanners Optical fingerprint scanners are the oldest method of capturing and comparing fingerprints. As the name suggests, this technique relies on capturing an optical image, essentially a photograph, and using algorithms to detect unique patterns on the surface, such as ridges or unique marks, Synaptics Fingerprint Sensors analysing the lightest and darkest areas of the image.

Just like smartphone cameras, these sensors can have a finite resolution, and the Synaptics Fingerprint Sensors the resolution, the finer details Synaptics Fingerprint Sensors sensor can discern about your finger, increasing the level of Synaptics Fingerprint Sensors. However, these sensors capture much higher contrast images than a regular camera.

These scanners typically have a very high number of diodes per inch to capture these details up close. Such a design is a bit bulky for a smartphone though, where slim form factors are important. As the technology is only Synaptics Fingerprint Sensors a 2D picture, prosthetics and even other pictures of good enough quality can be used to fool this particular design.

With increasing demand for tougher security, smartphones have unanimously adopted superior capacitive scanners, and the falling cost of technology has made capacitive alternatives viable for mid-range products too. However, with the move towards bezel less displays, smaller optical modules may make a comeback, as they can be embedded underneath the display glass and only require a small area footprint. Synaptics, which develops a range of scanner for smartphones and other products, unveiled its Natural ID FS optical fingerprint sensor with this in mind.

Capacitive scanners The most commonly found type of fingerprint scanner used today is the capacitive scanner. Instead of creating a traditional image of a fingerprint, capacitive fingerprint scanners use arrays tiny capacitor circuits to collect data about a fingerprint.

As capacitors can store electrical charge, connecting them up to conductive plates on the surface Synaptics Fingerprint Sensors the scanner allows them to be used to track the details of a fingerprint. An op-amp integrator circuit is used to track these changes, which can then be recorded by an analogue-to-digital converter.

The theory and architecture behind a capacitive fingerprint scanning chip. Slideshare Once captured, this digital data can be analysed Synaptics Fingerprint Sensors look for distinctive and unique fingerprint attributes, which can be saved for a comparison at a later date.

What is particularly smart about this design is that it is much tougher to fool than an optical scanner. The only real security risks come from either hardware or software hacking.

Creating a large enough array of these capacitors, typically hundreds if not thousands in a Synaptics Fingerprint Sensors scanner, allows for a highly detailed image of the ridges and valleys of a fingerprint to be created from nothing more than electrical signals. Just like the optical scanner, more capacitors results in a higher resolution scanner, increasing the level of security, up to a certain point.

Due to the number larger number of components in the Synaptics Fingerprint Sensors circuit, capacitive scanners can be a little pricey.

As many consumers complained at the time, this method was very finicky and often required several attempts to scan the Synaptics Fingerprint Sensors correctly. Fortunately, these days, the simple press and hold design is far more common.

Looking forward, Synaptics has also unveiled its latest FS capacitive scanner that supports new UI features. These include soft button support to act as navigation keys, force sensing capabilities, and swipe gesture support.

In future, many more devices may support a wider variety of swipe and navigation features using their fingerprint scanners. Ultrasonic scanners The latest fingerprint scanning technology to enter the smartphone space is an ultrasonic sensor, which was first announced to be inside the Le Max Pro Synaptics Fingerprint Sensors.
