Possac lets any business run a virtual queue. Staff add customers in seconds, or customers scan a QR code at the entrance and join themselves — no phone number required. Customers get an SMS with their position and estimated wait time, leave, run errands, and come back only when it's their turn. No crowded waiting rooms, no lost customers. Works for salons, barbershops, pharmacies, banks, and any business where people physically wait. Free to start, no app download needed, set up in under 2 minutes.
