The Fingerprints company has released data about the new sensor that incorporates the Xiaomi Redmi K30, being the first smartphone of the company that adds the latest developed in ultra-thin sensors on the side of the manufacturer company Fingerprints, a company that we have already previously talked about her being the company in charge of supplying Xiaomi with this technology in fingerprint sensors in the Xiaomi Mi 8, Mi 9, PocoPhone F1 …
The Swedish firm Fingerprint Cards AB has just launched the FPC1540 thin side capacitive touch sensor for biometric authentication. Located on the side of the Xiaomi Redmi K30 inside the power button, the sensor is also suitable for the latest smartphone designs, including borderless and foldable phones.
The era of folding smartphones is upon us. Market research firm ABI Research has predicted that shipments of smartphones with some type of folding, flexible or rolling screen will take off from 2020, with a growth that will reach 228 million in 2028. It is expected that the total number of devices with the technology will go from 1.8 million in 2019 to 240 million in 2028, at a compound annual rate of 72%.
The FPC1540 sensor that mounts the Redmi K30, according to Fingerprints, is an elongated and ultra-thin sensor (2.4 mm x 11.0 mm) that is presented on one side of the smartphone and adapts to folding and thin devices. The reduction in size is, in fact, its biggest improvement compared to previous versions, said Ted Hansson, senior vice president of Business Line Mobile at Fingerprints. “In the latest smartphones, where there is no space to place fingerprint sensors on the front or back of the devices, this sensor can be in them. The space limitation is also true that premium in this first generation of 5G phones since they have significantly higher energy consumption and require larger batteries. Under the screen and in the back, The FPC1540 sensor that mounts the Redmi K30 does not require a metal edge, known as a bevel, and is covered with an aerosol coating that is fully customizable to match the color of the device. “The sensors blend perfectly in the phone, which means that manufacturers don’t have to compromise the design to provide biometric security,” said Hansson.
No borders, no bezel: Xiaomi first introduced the concept without a bezel with their Mi Mix phones in 2016. Today, almost all OEM manufacturers have launched a smartphone without a bezel, and the trend is here to stay. For those who want to have a full screen without borders, Hansson said that “a sensor on the side is a bright alternative that is noticeably cheaper.”
Commenting on the price and reducing complexity, Hansson said that fewer components are needed, which means that it is “cost-effective and simpler” to integrate it. “In addition, by offering multiple functions, the sensor eliminates the need for additional buttons.”
Xiaomi Redmi K30 Supply of 8 out of 10 OEM
Biometric authentication has come a long way in recent years. Integrated into the first Android smartphone almost five years ago, fingerprint touch sensors are progressively surpassing the PIN as the preferred authentication method of consumers. According to ABI Research, the consumer market is expected to reach approximately 1.26 billion shipments of fingerprint sensors by the end of 2019.
In May 2019, Fingerprints announced that it had sent one billion biometric sensors worldwide, “supplying more than 400 different models of mobile devices, in 8 of the 10 OEM smartphones,” said Hansson. The company said that its commitment to R&D has been fundamental to this achievement. “Our active capacitive touch sensors, combined with advanced internal software and algorithms, have allowed us to reach the optimum point between capturing the best image with the smallest sensor, in the fastest time, using the lowest power. This has allowed us to reduce the size and cost of our sensors «.
In parallel, Fingerprints states that it has maintained a high level of biometric performance and safety. «From allowing users to touch at any angle and registering with just a few touches, to minimizing false rejection and, more importantly, almost eliminating the possibility of false acceptance: our advanced software does the job, so consumers benefit from the best UX »
2020 insight of Xiaomi
With fingerprints widely used in smartphones, and about 70% of all devices sent now, including biometric data, Fingerprints predicts the growth of multimodal solutions. “This would combine the familiarity of the fingerprint with other biometric identifiers, such as the face and the iris, to allow users to authenticate at their convenience, in a variety of environments, all with enhanced security.” As an example, the recently launched Touchless from company 2.0 combines iris with facial recognition.
In the smartphone industry, biometrics increasingly meets the needs of manufacturers who launch devices with borderless, buttonless, and notch designs, Hansson said. The launch of the FP1540 slim side mount sensor that mounts the Redmi K30 is an illustration, along with the trend of the sensors below the screen. “This new sensor can be placed under the screen, and this is something Fingerprints is currently working on, using optical technology.”
The adoption of biometric technology does not stop with mobile phones and is progressively expanding in other verticals, including payments and access control. “The possibilities are endless,” Hansson concluded. “Increasing use cases for biometrics are emerging in an attempt to eliminate PINs and passwords that consumers face when accessing both their physical and digital lives.”
So we hope to continue seeing effective improvements in Xiaomi smartphones thanks to the manufacturing agreement with Fingerprints. We hope to see a breakthrough of it in the Xiaomi Mi 10 or Redmi K30 Pro.
