Hajj 2026 is shaping up to be the most technologically advanced pilgrimage in history. From mandatory smart cards to GPS-enabled wristbands and AI-powered crowd management, Saudi Arabia is deploying an unprecedented digital infrastructure to protect and guide the estimated 1.8 million pilgrims expected this season.
The Nusuk Smart Card
Every registered pilgrim must carry a Nusuk smart card from arrival to departure. The card combines personal identification, medical records, and accommodation data into a single document that functions as both a physical and digital pass. It grants access to the holy sites at Mina, Arafat, and Muzdalifah, organises bus boarding and group transfers, and enables authorities to reunite lost pilgrims with their groups using embedded accommodation data.
The digital version of the card is accessible through the Nusuk app for international pilgrims and through the Tawakkalna app for domestic pilgrims within Saudi Arabia. If lost, pilgrims can request a replacement through their service provider, visit a Nusuk Care Centre, or call the Unified Call Centre at 1966.
Smart Wristbands with GPS and Health Monitoring
Several countries have equipped their pilgrims with smart wristbands that go beyond simple identification. India's delegation of 175,025 pilgrims has been issued wristbands designed to track and locate pilgrims when needed. According to reports, some of these wristbands monitor blood oxygen levels and heart rate, alerting medical teams if a pilgrim shows signs of heat exhaustion - a critical feature given that temperatures in Makkah during Hajj can exceed 45 degrees Celsius.
The wristbands work alongside a broader health monitoring infrastructure. The Nusuk app sends hydration reminders and heat advisories based on the pilgrim's location, while emergency services locations are mapped in real time so that help can be reached quickly.
AI-Powered Crowd Management
The Nusuk app now offers live crowd density mapping for the Grand Mosque and key Hajj locations. Pilgrims can check how crowded the Tawaf area is before heading there, allowing them to plan their worship around the less busy periods. Behind the scenes, Saudi authorities are using AI-powered analytics for predictive crowd modelling - anticipating where bottlenecks will form and deploying resources before they become dangerous.
Over 230 surveillance cameras have been installed at the Miqat locations and around the Grand Mosque, feeding data into the central monitoring system. The multi-level Jamarat bridge, where millions of pilgrims perform the pelting ritual over just a few days, is a particular focus of the AI crowd-management effort.
The Nusuk App: 51 Million Users
The Nusuk platform has surpassed 51 million users globally, consolidating more than 130 digital services into a single app. These include Umrah permit issuance, Rawdah visit bookings in Madinah, hotel and Haramain train reservations, flight arrangements, and the real-time crowd monitoring mentioned above. A built-in AI assistant answers pilgrim questions via voice and text in multiple languages.
The app supports dozens of languages across 180+ countries, with large typography to accommodate older pilgrims who may be less familiar with digital interfaces.
Privacy Concerns
The digital transformation has not been without criticism. Some observers have raised questions about the volume of data being collected - location tracking, health information, identity documents, and transaction records - and how this data is stored and shared. The Dhaka Tribune noted that the high-tech approach delivers "more safety but less privacy," a trade-off that some pilgrims accept willingly while others find uncomfortable.
Saudi authorities have emphasised that the technology exists solely to enhance pilgrim safety and service quality. The data is used for real-time operational decisions - such as redirecting crowds or dispatching medical aid - rather than long-term surveillance.
What Pilgrims Should Do
Pilgrims should download the Nusuk app before travelling (available on Apple App Store and Google Play), ensure their Nusuk card details are up to date, and familiarise themselves with the app's features - particularly the crowd density map and emergency services locator. Those with smart wristbands should wear them at all times during the Hajj rites. The technology is there to help, and pilgrims who engage with it will have a safer and smoother experience.
