CT in Smart City
Touchless technology is a promising way to maintain peo-
ple’s health and hygiene, especially during crisis such as
the COVID-19 outbreak. A recent
survey reports that due
to the COVID-19 pandemic about 95% of the people pre-
fer touchless services like touch-free alcohol or soap dis-
pensers, touch-free faucets, etc. Contactless or touch-free
technologies can be leveraged
for different products and
services. Some contactless technologies that can promote
smart cities infrastructures are discussed in the following
sections.
Touchless Biometric Solutions for Access Control
Fingerprints, iris, and face recognition are the biom-
etrics
elements used for identity, temperature sensing,
and access control in many organizations. To reduce the
risk of disease spreading in workspaces, a Swiss-based
company named touchless biometric solution (TBS) has
emerged offering two services, the TBS 2D
Eye and the
3D Terminal.
2D Eye System
Serves as a combination between two techniques, i.e., the
iris scanning and the face detection, reaching accuracy lev-
els of 95% and enhancing the security of access points. The
process starts with facial identification
through images cap-
tured using a highly sensitive camera. Then, iris details are
extracted from the images and analysed for the user authen-
tication [
