Alps Alpine has announced the launch of what they believe to be the world’s smallest class surface-mount type TACT Switch, the “SKUB Series.” At just 2.4mm×1.4mm×0.55mm (W×D H), this switch achieves a smaller size than previous models, while maintaining the same tactile feel and durability. The SKUB series has an actuating force of 1.6N and a switching travel of 0.11mm. The initial contact resistance is 500mΩ. The IP68-protected component has a long service life of 500,000 switching cycles. It is designed for switching currents of 50mA at a maximum of 12VDC. Mass production began in September 2024.

SECORA Pay Bio enhances convenience and trust of biometric contactless payment
As the payment world moves towards digitalisation, the need to protect digital identities and transactions has never been more important. In addition to standard contactless payment cards, biometric payment cards are a promising development in this area and are gaining in popularity. Against this backdrop, Infineon has announced SECORA Pay Bio, an all-in-one biometric payment card solution that complies with Visa and Mastercard specifications. It integrates Infineon’s enhanced SLC39B system-on-chip (SoC) Secure Element and the FPC1323 sensor by Fingerprint Cards AB (Fingerprints) into the Infineon Biometric Coil on Module (BCoM) package, leveraging the key advantages of inductive coupling technology. The solution uses the fingerprint credentials securely stored on the card as a second authentication factor, enabling a convenient and trusted contactless payment experience.
