Abstract
Intelligent systems are enhancing city environments and improving their overall performance in all possible aspects. Innova-
tions in the field of information and communication technologies (ICT) and the proliferation of big data, internet-of-things
(IoT), and cloud (BIC) infrastructures revolutionize the existing agile city ecosystems while effectively
addressing customers
and citizens needs. In this paper, we address the technology-driven applications that are capable
of influencing the existing
city infrastructures during their transformation towards smart cities with contactless technologies. We present applications,
design
principles, technology standards, and cost-effective techniques that leverage BIC for contactless
applications and
discuss user interfaces deployed in smart city environments. We further discuss state-of-the-art sensing methods and smart
applications that support cities with smart contactless features. Finally, a case study is reported
on how BIC can assist in
efficiently handling and managing emergency situations such as the COVID-19 pandemic.
