The pilgrimage (hajj) in Mecca has spawned a slew of religious apps, tablet Qurans and faith-based gadgets.
At the peak of Mount Arafat, numerous Muslim pilgrims were absorbed in Quranic verses displayed on their smartphones – rapidly replacing traditional printed holy books.
"Of course I read the Quran on my phone ... it's much more simple," said Egyptian teacher Ahmad Salim, 46, who had travelled to Saudi Arabia for the hajj, one of Islam's five pillars.
For the first time in the hajj's history, 5G super high-speed mobile technology was deployed around the holy sites to allow the faithful to transfer data at breakneck speeds.
Tech giants Zain and Nokia even demonstrated "advanced virtual reality ... allowing users to experience the hajj remotely as if they were there", using 360° high-definition video over 5G.
Many pilgrims snapped selfies over the five-day rite, held this year Aug 9 to 14, and sent video clips to friends and family back home.
Almost 2.5 million Muslims have travelled to Mecca in western Saudi Arabia, closed to non-Muslims, for the religious gathering, which is one of the world's largest and most logistically complex.
The hajj has taken on an increasingly high-tech dimension in recent years with the emergence of mobile phone apps designed to help pilgrims from around the world navigate their experience.
Software exists to help visitors get around Mecca and the surrounding area as well as access medical services and properly follow religious rites.
Saudi's hajj ministry even sends text messages to pilgrims with a variety of information and advice.
A major digital innovation for this year's hajj was the introduction of electronic hajj visas "delivered online for the first time without necessitating a consulate visit. It's been a success," said hajj ministry official Hassan Qadi.
'It's very useful'
"It's very practical, especially for those travelling with family," said Jordanian Abderrahman Shdaifat, 44, who made his first hajj.
The authorities have also increasingly turned to technology to improve the hajj experience and avoid incidents like the stampede that claimed some 2,300 lives in 2015.
In the wake of that tragedy, pilgrims are now issued with electronic bracelets containing their personal data.
"All of their information is loaded, a bit like an ID card. If you can't read or write and you get lost, you can give it to anyone and they can help you find your address. Technology helps ease the hajj," said Sami Abdelaziz, a 37-year-old Saudi pilgrim.
Shdaifat, the Jordanian pilgrim, sheltered under an umbrella from the heavy rains that have lashed the Mina Valley outside Mecca, said of the bracelets: "If a pilgrim gets separated, their group can locate them.
"It's very useful."
Saudi authorities also fitted GPS trackers to 18,000 shuttle buses to monitor the flow of pilgrims.
Shdaifat brandished a second bracelet that gave him access to the metro system connecting Mecca's various pilgrimage sites.
Classic watches and alarm clocks are also losing ground to phone-based tools that alert worshippers to their five daily prayers.
"Nearly all the pilgrims have it," said Egyptian Ahmad Salim. – AFP Relaxnews
