The Bureau of Civil Aviation Security (BCAS) on Thursday said body scanners should be made mandatory at all major airports within a year.
It also informed that body scanners will be made mandatory at all the other airports in two years.
A full-body scanner is a device used to scan an individual's body for security, screening purposes, without making physical contact.
The technology helps in seeing an alternate wavelength image of a person's body to detect any suspicious items.
