determining the display arrangement of the one or more control icons comprises:

identifying, from among a plurality of predefined orientations, an orientation that is a closest match to the physical orientation of the one or more physical resources relative to the determined physical orientation of the mobile device of the user; and

identifying, from among a plurality of predefined graphical key selection interfaces, a graphical key selection interface that comprises the one or more control icons arranged according to the identified orientation; and

causing display of the one or more control icons in accordance with the determined display arrangement comprises providing, to the mobile device of the user, the identified graphical key selection interface.

9. The method of claim 1 , wherein:

determining the display arrangement of the one or more control icons comprises generating a graphical key selection interface that comprises the one or more control icons arranged according to the physical orientation of the one or more physical resources relative to the determined physical orientation of the mobile device of the user; and

causing display of the one or more control icons in accordance with the determined display arrangement comprises providing, to the mobile device of the user, the generated graphical key selection interface.

10. The method of claim 1 , further comprising:

receiving, from the mobile device of the user, a selection of a particular control icon from the one or more control icons; and

enabling the user to use a particular key, from among the one or more keys, that corresponds to the selected control icon to access a particular physical resource from among the one or more physical resources.

11. The method of claim 1 , further comprising:

determining a geographic location of the mobile device of the user.

12. The method of claim 11 , wherein determining the geographic location of the mobile device of the user comprises receiving an indication of a geographic location from a location-sensing device of the mobile device of the user.

13. The method of claim 11 , wherein determining the geographic location of the mobile device of the user comprises processing triangulation information received from a plurality of devices that are in communication with the mobile device of the user.

14. The method of claim 11 , wherein identifying one or more keys that are associated with the credential and that enable access to one or more physical resources associated with the credential-issuing organization comprises:

determining a geographic region associated with the one or more physical resources;

comparing the geographic location of the mobile device of the user with the geographic region associated with the one or more physical resources; and

determining a match between the geographic location of the mobile device of the user and the geographic region associated with the one or more physical resources, and

determining that the one or more keys correspond to the one or more physical resources for which the associated geographic region was determined to match the geographic location of the mobile device of the user.

15. The method of claim 11 , further comprising:

determining one or more credential-issuing organizations having associated physical resources that are in a vicinity of the geographic location of the mobile device of the user; and

providing, to the mobile device of the user, information regarding the one or more credential-issuing organizations and the associated physical resources that are in the vicinity of the geographic location of the mobile device of the user.

16. The method of claim 1 , wherein authenticating a user of a mobile device comprises:

receiving, from the mobile device of a user, authentication information associated with the credential and the one or more keys issued by the credential-issuing organization; and

determining that the authentication information has been authorized by the credential-issuing organization.

17. The method of claim 1 , further comprising:

receiving, from a system operated by the credential-issuing organization, the credential and the one or more keys issued to the user by the credential-issuing organization; and

adding the credential and the one or more keys to a user account of the user.

18. The method of claim 1 , further comprising:

providing, to the mobile device of the user, based on determining that the user's authentication information has been authorized, a representation of a credential that comprises at least one of a Quick Response (QR) Code, an alphanumeric code, or a short-range wireless code.

19. A system comprising:

one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
