Claim:
1. A system comprising: a first personal digital key associated with an owner, the personal digital key capturing, at the first personal digital key, biometric information from a first person and authenticating, at the first personal digital key, the first person as the owner of the first personal digital key based at least in part on the captured biometric information, the first personal digital key including an encrypted digital key identifier unique to the first personal digital key for enabling automatic authentication of the first personal digital key and, upon the first personal digital key authenticating the first person as the owner based on the captured biometric information, transmitting that same encrypted digital key identifier without the biometric information; and an account linking system that performs automatic authentication of the first personal digital key, the account linking system including a receiver or decoder circuit integrated into a first device, the receiver or decoder circuit having a range defining proximity and automatically authenticating the first personal digital key based on the encrypted digital key identifier received responsive to the first personal digital key being in proximity to the receiver or decoder circuit and responsive to the first personal digital key authenticating the first person as the owner, the first personal digital key and the receiver or decoder circuit automatically authenticating each other when in proximity to one, the receiver or decoder circuit detecting an item that is included in a plurality of items that are associated with the first personal digital key in a linked account responsive to authentication, the linked account, tracking the plurality of items associated with the first personal digital key, stored in a central database and the linked account being: the account linking system accumulating data associated with a plurality of personal digital keys associated with different persons in an area including content received at a second device in use by an owner of a second personal digital key, the plurality of personal digital keys including the first personal digital key and the second personal digital key, determining devices associated with the area including the first device and the second device, determining to provide content similar to the content received at the second device in use by the owner of the second personal digital key to the first device based on satisfaction of a predefined threshold associated with the accumulated data associated with the plurality of personal digital keys in the area and including the content received at the second device in use by an owner of a second personal digital key as well as the linked account, the receiver or decoder circuit including a non-user-modifiable unique identifier associated with the receiver or decoder circuit and different from the encrypted digital key identifier received from the first personal digital key, the non-user-modifiable unique identifier associated with the receiver or decoder circuit used by a server to encrypt the determined content, the determined content received at the first device and sent from the server.
