Techniques are provided to automate at least some of the information gathering required for check-in using a mobile device. A user may enter at least some required information using a mobile application on a mobile device. The mobile application may convert the entered data into a Quick Response (“QR”) code or other type of readable form that may be read or received by a device at the location of check-in. The information entered may be stored in the mobile device's memory and may be modified for future check-ins. A user would enter the location of check-in and present the mobile phone containing the information previously entered by the user to a reader at the location. The reader reads the information which may be transmitted to the location's database. Using the information submitted, the user may be checked in automatically.
