Booking

In law enforcement and criminology booking refers to the intake process of admitting an arrestee or convict into a prison or police station. In the United States and United Kingdom, this process involves being fingerprinted, photographed (having a mugshot taken), and having one's possessions confiscated. What an arrestee is allowed to keep in their possession varies depending on the exact facility, county, etc, inmates are usually allowed to keep prescription glasses with no tint on the lenses, hearing aids and other approved medical devices, their legal papers and a few other things. In the United States, if an arrestee can't bail out of jail, or they're beginning a prison term, they're issued a prison uniform and other jail issued items and informed of the facility's rules and regulations.
Booking also means making an appointment of some kind.
