Scan-to-Unlock Mobile Toilets

Scan-to-unlock mobile toilets mainly include the mobile public toilets in Fuzhou, Fujian, the smart public toilets piloted in New York, and the first night-time scan-to-open public toilet in Shanghai, each with distinct characteristics.

Mobile public toilets in Fuzhou, Fujian: Located by the seaside, these are container-style toilets that integrate multiple functions, including toilets, showers, and vending machines. The scan-to-unlock process is relatively simple. A QR code is posted on the toilet door, and scanning it brings up a 'User Notice' reminding users to 'scan to open the door and lock it from the inside after entering'. In terms of payment, the original price was 10 yuan, which was later adjusted to 2 yuan. Although a countdown timer is set, users can continue to use the toilet after it expires. The inside of the toilet is equipped with a manual lock that, once locked, cannot be opened from the outside, ensuring user privacy and safety.

Smart public toilets piloted in New York: These toilets feature advanced functions such as automatic timing, intelligent warnings, and remote monitoring. They strictly enforce a 10-minute usage limit, with the system providing voice reminders to users before the countdown ends. If the time expires, the sliding door automatically opens, and bilingual (English and Spanish) prompts are played. If someone refuses to leave, the equipment manufacturer's staff receive an alert and may contact the police if necessary. For unlocking, the design is智能化 (smart), allowing citizens to enter by sending a text message or swiping a community-specific card, demonstrating the integration of technology and management.

First night-time scan-to-open public toilet in Shanghai: Located at the intersection of Century Avenue and Yanggao Middle Road in Pudong, this is a mobile toilet with three stalls. After the cleaner leaves at 9 PM, it switches to night mode. Passersby can scan a code to register and then enter a stall, with the door automatically locking upon entry. After using the toilet, pressing the open-door button unlocks it. If a user does not exit after 15 minutes, the system automatically 'alerts' the night-shift staff to contact the user, ensuring orderly management and safety of the public toilet at night.
