Earlier this week, Redmi officially released an article through its official Weibo account, a Chinese microblogging website, explaining why its latest K40 series of smartphones have its fingerprint sensor mounted on the side.
As per the article, the Chinese tech giant had to consider various factors while making the decision to have the fingerprint sensor placed on the side. This includes aesthetics and the overall look of the device along with its unlocking speeds. The last gen Redmi K30 series also featured a side mounted fingerprint scanner as well, although, that sensor required a small area to be cut out from the handset’s frame surface. But with the K40 lineup, the company housed the sensor on the button itself.
Furthermore, the fingerprint sensor on the K40 series is also thicker due to the button, which also enhances its structural strength and raises the height of the buttons as well. Similarly, due to its curved surface, the company’s team was also able to improve the materials and craftsmanship of the fingerprint button’s surface. This, in turn, improves its reception rate, which is also further optimized by recognition algorithm to ensure a quick and accurate unlock.
The Redmi K40 series was launched last month and is the company’s current flagship lineup. It features top notch specifications like the Qualcomm Snapdragon 870/888 processor, with its price starting from 1999 Yuan (roughly 307 US Dollars). The brand also offers functions to this fingerprint scanner, while it is also directly tied with the Alipay health code as well.
