Claim:
1. A method for electronic transaction processing comprising: automatically and wirelessly receiving, using one or more processors, a first biometric sample from a first personal digital key device after the first personal digital key device has entered a proximity zone within a readable coverage area, wherein the first personal digital key device includes the first biometric sample and a first biometric profile associated with a valid user of the first personal digital key device, wherein the first biometric sample is a subset of the first biometric profile; automatically and wirelessly receiving, using the one or more processors, a second biometric sample from a second personal digital key device after the second personal digital key device has entered the proximity zone within the readable coverage area, wherein the second personal digital key device includes the second biometric sample and a second biometric profile associated with a valid user of the second personal digital key device, wherein the second biometric sample is a subset of the second biometric profile; receiving, using the one or more processors, a biometric input from a user; comparing, using the one or more processors, the biometric input to a collection of biometric samples received from and associated with personal digital key devices within the proximity zone for a match, the collection of biometric samples including the first biometric sample and the second biometric sample when the first personal digital key device and the second personal digital key device are within the proximity zone within the readable coverage area; determining, using the one or more processors, that the biometric input from the user matches the first biometric sample from the first personal digital key device; based on the biometric input matching the first biometric sample from the first personal digital key device in the collection of biometric samples received from and associated with personal digital key devices within the proximity zone, determining, using the one or more processors, that the first personal digital key device from personal digital key devices within the proximity zone is to be associated with a transaction; after determining that the first personal digital key device is associated with the transaction, determining, using the one or more processors, whether the biometric input of the user matches the first biometric profile associated with the valid user of the first personal digital key device; authenticating, using the one or more processors, without user intervention, the first personal digital key device after the first personal digital key device has entered the readable coverage area; and authorizing, using the one or more processors, the transaction responsive to the authentication of the first personal digital key device and determining that the biometric input matches the first biometric profile associated with the valid user of the first personal digital key device.
