He said till now it is mandatory for a visitor to get entry tickets from the ASI windows. The tourists, both Indian and foreigners, have to wait for hours to get ticket. “Instead if e-tickets with bar codes are introduced it will save tourists from long wait,” Yadav said. Besides, Yadav said, that more facilities like X-ray machines and Door Framed Metal Detectors (DFMD) should be installed to check bags and frisking. This will save precious time of the visitors.
