What do tour groups need passport photos for?

The main reason why tour groups ask for passport photos is to verify the identity information of passengers and ensure the safety and smooth progress of tourism activities. Specifically, the tour group needs to know the passenger's name, ID number, date of birth, passport number and other personal information, so as to check and confirm in the process of visa application, hotel reservation and air ticket purchase. Passport photos are one of the most important personal information, which can help tour groups to quickly and accurately verify the identity information of passengers and avoid the situation of incorrect identity information or fraudulent use of other people's passports.
