Introducing Loc-HapPIN, a pioneering PIN-input approach developed for touchscreen and keypad devices, transforming user experience and enhancing safety. This innovative method employs localized haptic feedback activated by a card swipe, allowing users to generate dynamic PINs based on the vibrations produced, minimizing the risk of PIN theft. In the event of unauthorized attempts, triggers security protocols, and sends a GSM message for identity verification within two minutes. A "yes" confirmation necessitates inputting the accurate PIN, reopening the shutter, while a "no" or absence of response initiates alternate authentication methods, such as fingerprint scanning. Incorrect PIN entries activate a stringent procedure, dispatching distress messages to specified contacts for manual shutter release, ensuring comprehensive device and user protection.
