The partnership has been further extended by three years.
This new collaboration agreement will see the duo tap new technologies, including the Internet of Things (IoT), extended reality, machine learning, and edge computing.
Accenture plans to deploy a centralised identity and access management solution to eliminate the need for customers to sign in through multiple accounts to access different applications.
Equipped with the new solutions, Changi expects that it will be able to engage passengers even before their arrival at the airport and also after they leave.
Additionally, the new agreement will see sharing of knowledge and skills with the CAG team.
CAG Enterprise Digital Ecosystem and Business senior vice-president Hung Jean said: “Changi Airport Group has always put our customers first; constantly enhancing the airport experience and pleasantly delighting our customers even when they are not travelling.
“In this next phase of our digital transformation journey, how we deliver the unique Changi experience, whether offline or online, to our customers remains key.
“We are happy to extend our collaboration with Accenture, which has proven to be a valuable partner with the ability to combine innovative design capabilities with technology and industry expertise.”
The tie-up between Accenture and CAG began in 2019 with the creation of a digital factory called digital, innovation, ventures and analytics (DIVA) to enable CAG to introduce new digital products and services.
Accenture Singapore country managing director Ng Wee Wei said: “We have been working closely with CAG to implement digital enhancements and infuse a culture of experimentation.
“As the line between the physical and digital continues to blur, organisations have the opportunity to address issues like trust, sustainability, safety, responsible access and use, diversity and more, helping set the stage for the future.
“We see many new possibilities to bring even more immersive collaborative, personalised and meaningful experiences to CAG’s customers.”
Last month, Changi Airport (SIN) received ExxonMobil’s first batch of sustainable aviation fuel (SAF).
