Concerts and schools are increasingly implementing "phone-free" policies using lockable pouches to enhance engagement and reduce distractions. This method, pioneered by companies like Yondr, gained prominence after artists such as Sir Paul McCartney used it, and is now being widely adopted in educational settings with reported benefits.

• Sir Paul McCartney performed a "phone-free" gig in Santa Barbara Bowl, requiring all 4,500 fans to place their phones in lockable pouches.
• Yondr, founded by Graham Dugoni, developed the magnetic pouch technology, and has worked with approximately 2.2 million schools in America, with about 250,000 children in 500 schools in England currently using their wallets.
• The pouches cost between £7 and £30 each, and schools like Vale of York Academy have reported improved academic performance and reduced bullying, with headteacher Gillian Mills noting fewer phone confiscations.
