if a first image of the user was received, then generate, at the reader device, a generated representation of the face of the user using the first image; capture, at the reader device, a second image of the user and generate a second representation of the face of the user using the second image; determine a likelihood of a match between the second representation and at least one of the first representation and the generated representation; and permit access by the user to a secure asset in instances where the likelihood of a match meets a threshold. ## Claims ### Claim 1 A non-transitory computer readable medium comprising executable code, that when executed by one or more processors, causes the one or more processors to: establish, responsive to a credential device of a user approaching a reader device, a secure wireless connection between the credential device and the reader device; receive, at the reader device from the credential device via the secure wireless connection, at least one of a first image of the user or a first representation of a face of the user; if a first image of the user was received, then generate, at the reader device, a generated representation of the face of the user using the first image; capture, responsive to receiving the first image of the user or the first representation of the face of the user from the credential device at the reader device, a second image of the user; generate a second representation of the face of the user using the second image; determine a likelihood of a match between the second representation and at least one of the first representation and the generated representation; and permit access by the user to a secure asset in instances where the likelihood of a match meets a threshold. ### Claim 2 (depends on 1) The non-transitory computer readable medium of claim 1, wherein the executable code, when executed by the one or more processors, causes the one or more processors to further: receive, responsive to the credential device of the user approaching the reader device, at the reader device from the credential device of the user, credential data; and validate, responsive to capturing the second image of the user at the reader device, the credential data. ### Claim 3 (depends on 2) The non-transitory computer readable medium of claim 2, wherein permitting access by the user to the secure asset comprises permitting access by the user to the secure asset in instances where both the likelihood of a match meets the threshold and the credential data is valid. ### Claim 4 (depends on 1) The non-transitory computer readable medium of claim 1, wherein the executable code, when executed by the one or more processors, causes the one or more processors to further establish the secure wireless connection for receiving at least one of the first image or the first representation. ### Claim 5 (depends on 1) The non-transitory computer readable medium of claim 1, wherein the secure asset is a physical asset. ### Claim 6 (depends on 1) The non-transitory computer readable medium of claim 1, wherein the secure asset is a logical asset. ### Claim 7 (depends on 1) The non-transitory computer readable medium of claim 1, wherein the threshold is a value selected to fall within an inclusive range corresponding to a 60% to 90% likelihood of a match. ### Claim 8 A device for permitting access to a secure asset, the device comprising: at least one processor; and memory storing instructions that when executed by the at least one processor cause the at least one processor to: establish, responsive to a credential device of a user approaching a reader device, a secure wireless connection between the credential device and the reader device; receive a first image of the user from the credential device via the secure wireless connection; generate a first facial recognition representation of a face of the user using the first image; capture, responsive to receiving the first image of the user from the credential device at the reader device, a second image of the user; generate a second facial recognition representation of the face of the user using the second image; determine a likelihood of a match between the first and second facial recognition representations; and permit access by the user to the secure asset in instances where the likelihood of a match meets a threshold. ### Claim 9 (depends on 8) The device of claim 8, wherein the instructions, when executed by the at least one processor, cause the at least one processor to further: receive, responsive to the credential device of the user approaching the reader device, credential data from the credential device; and validate, responsive to capturing the second image of the user at the reader device, the credential data. ### Claim 10 (depends on 9) The device of claim 9, wherein permitting access by the user to the secure asset comprises permitting access by the user to the secure asset in instances where both the likelihood of a match meets the threshold and the credential data is valid. ### Claim 11 (depends on 10) The device of claim 10, wherein the device comprises a reader device connected with a facial recognition module that is external to the reader device, wherein: the reader device is configured with the instructions that cause the at least one processor to receive credential data from the credential device and validate the credential data; and the facial recognition module comprises an optical sensor and is configured with the instructions for capturing the second image of the user. ### Claim 12 (depends on 8) The device of claim 8, wherein the instructions, when executed by the at least one processor, cause the at least one processor to further establish a secure wireless connection for receiving the first image. ### Claim 13 (depends on 8) The device of claim 8, wherein the device comprises a reader device connected with a facial recognition module that is external to the reader device, the facial recognition module comprising an optical sensor for capturing the second image of the user. ### Claim 14 (depends on 13) The device of claim 13, wherein the memory storing instructions is divided between the reader device and the facial recognition module. ### Claim 15 A device for permitting access to a secure asset, the device comprising: at least one processor; and memory storing instructions that when executed by the at least one processor cause the at least one processor to: establish, responsive to a credential device of a user approaching a reader device, a secure wireless connection between the credential device and the reader device; receive a first representation of a face of the user from the credential device via the secure wireless connection, the first representation generated from a first image of the user; capture, responsive to receiving the first image of the user from the credential device at the reader device, a second image of the user; generate a second representation of the face of the user using the second image; determine a likelihood of a match between the first and second representations; and permit access by the user to the secure asset in instances where the likelihood of a match meets a threshold. ### Claim 16 (depends on 15) The device of claim 15, wherein the instructions, when executed by the at least one processor, cause the at least one processor to further: receive, responsive to the credential device of the user approaching the reader device, credential data from the credential device; and validate, responsive to capturing the second image of the user at the reader device, the credential data. ### Claim 17 (depends on 16) The device of claim 16, wherein permitting access by the user to the secure asset comprises permitting access by the user to the secure asset in instances where both the likelihood of a match meets the threshold and the credential data is valid. ### Claim 18 (depends on 17) The device of claim 17, wherein the device comprises a reader device connected with a facial recognition module that is external to the reader device, wherein: the reader device is configured with the instructions that cause the at least one processor to receive credential data from the credential device and validate the credential data;
