ZenLocked supplies lockable phone pouches that let organisations run phone-free spaces without collecting or storing devices. On arrival, a phone goes into a pouch that is then locked, and the owner keeps hold of it throughout. To use the phone again, they step outside the phone-free zone and tap the pouch on an unlocking base.

In schools and universities, the pouches are used to keep phones out of classrooms, lecture halls and study areas during the day and during exams. The same approach is offered for workplaces, courts, music venues, hospitality and private events such as weddings and conferences, where phones are locked away to limit distraction, recording or access to sensitive settings.

The company publishes a blog covering phone-free school policy, including guides to phone bans across European countries.
