Ticketing information may be ascertained based on the identification. The ticketing information may be provided, actions may be performed using the ticketing information, and so on. In some implementations, a checkpoint device receives biometric data from a person. A digital representation of the biometric data is used to obtain an identifier from an identification system. The digital representation of the biometric data may not be included in the identifier. The identifier is used by to obtain ticketing information from a ticketing system. The person may be allowed or denied entry into a ticketed area based on the ticketing information. ## Claims ### Claim 1 A method comprising: receiving an identifier for a person, wherein the identifier is obtained from an identification system that compares a digital representation of an image of the person against one or more stored images, wherein the identifier does not include the digital representation of the image;
