fingerprint scanner success stories

One success story is in mobile phones. For example, Apple's Touch ID. It made unlocking the phone much more convenient and secure. Users no longer had to type in long passwords. It also added an extra layer of security for mobile payments, which increased user confidence in using their phones for financial transactions.

Sure. In the healthcare industry, fingerprint scanners are used for patient identification. This helps prevent medical errors like wrong - patient treatments. For instance, when a patient is about to receive medication or a procedure, the fingerprint scanner ensures it's the right person. It has been successful in improving patient safety.

Finger painting was a type of art painting that was often done in children's art classes. In the fingerprint painting, the child needed to pay attention to the amount of paint used. It could not be too much, or the shape of the picture would not be seen. It could not be pressed too heavily or too lightly. The paint could not be too much or too dry. The force must be even. The fingerprint painting could draw various shapes and patterns through the fingerprint. There were some books on fingerprint painting that could provide guidance and techniques, such as The Complete Collection of Finger Prints and Magic Finger Prints. The fingerprint painting allowed children to use their imagination to create exquisite handmade works.

The largest external size of the scanner shutter product was 121.80mm x 88.86mm x 25.77mm. The average thickness of the plastic part was 2.70mm. The plastic part was made of PC+ABS. The shrinking rate was 1.005. The mass of the plastic part was 18.35g. The technical requirements of the plastic part were that there should be no defects such as peaking, incomplete injection molding, flow lines, pores, warping, silver lines, cold material, spray lines, bubbles, etc. The plastic part in the product drawing was a complex support. Although it did not have a complex surface, its height fluctuated greatly. Its shape was complex and its shape was symmetrical. It played a functional support role in the product and was a key component inside the product. There are four vertical walls in the middle, each with a through hole of? 3.2. The four holes here must ensure the requirements of the degree of concentration to facilitate the flexible rotation of other related parts after assembly. The two ends of the U-shape had a hook to assemble other components. There was a hook at the bottom of the U-shape. All these installation parts required accurate size, so there were high requirements for geometric tolerance. The difficulty of the mold design was the choice of the mold opening direction, the design of the parting surface, and the design of the four-hole sliding block core-pulling mechanism. Due to the large size of the plastic part, the complex structure, the fluctuation of the parting surface, and the many rubbing positions, the mold was ranked first. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
