New rules now permit pubs and shops to accept government-approved digital ID apps as proof of age, placing a smartphone beside the passport and driver's license as a legitimate token of identity. The shift is framed as progress — less friction, more privacy — yet it arrives carrying the familiar tension of any technology that promises to simplify life while quietly redrawing who belongs and who is left behind.
