Why Wait Time Matters
67%

Customers Leave After 10 Minutes

Two-thirds of customers abandon a queue if the wait exceeds 10 minutes, directly impacting revenue and satisfaction scores.

12%

Satisfaction Gain per Minute Saved

Each one-minute reduction in average wait time corresponds to a 12% increase in customer satisfaction ratings, according to service operations research.

3x

Perceived vs Actual Wait

Customers perceive unmanaged waits as three times longer than actual time. Digital tokens and SMS updates close that perception gap immediately.

Vizitor Queue Management
How Vizitor Reduces Queue Time
1

Pre-Registration

Patients and customers fill their details online before they arrive. Counter staff skip data entry and go straight to serving, cutting per-person service time significantly.

2

Digital Token System

Visitors receive a digital token on arrival. They can sit, move around, or wait outside, eliminating physical crowding and reducing perceived wait time.

3

SMS Notifications

Automatic SMS alerts notify customers when their turn is approaching. Staff can also broadcast delay messages, keeping the entire queue informed and calm.
