An event queue works when visitors arrive continuously and one desk cannot serve everyone at once. A public QR code lets each person join from a phone and keep a private ticket, while the operator calls visitors in order from a separate management page. The setup is lighter than appointment booking and suits entrances, badge pickup, workshops, merchandise desks, and short consultations.
Use a live queue for arrivals, not scheduled appointments
Choose Queue when arrival order matters and service happens as capacity becomes available. It is not suitable when every visitor needs a booked time, payment, identity verification, medical priority, or assignment to a specific member of staff.
Place the QR code before the physical line starts
Print the public QR code at the entrance and registration point, with a short readable URL as backup. Visitors should see it before they form a crowd. Keep the private management link only on operator devices and never print it on the public sign.
Give visitors three short instructions
Tell people to scan, join without an account, and keep the private ticket page open. Explain whether they should watch the screen, listen for a number, or remain nearby. Avoid collecting names or details the event does not need.
Use one consistent operator flow
Call the next ticket, then mark it served, no-show, or removed before moving on. Pause new entries when the desk must catch up and close the queue when registration ends. Consistent states keep the public wait count understandable.
Test the event queue before doors open
Join twice from an ordinary phone, verify ticket order, call and complete one visitor, test pause and resume, and scan the printed code from a second device. Confirm that staff know which link is public and which one controls the queue.
