## Abstract

While a user is located outside a verification area, one or more computing devices are used to obtain, in real time, a first image of the user. The one or more computing devices are used to store the first image among a plurality of images. While the user is located inside the verification area, the one or more computing devices are used to obtain identification information from the user. The one or more computing devices are used to identify, based on the identification information, a second image that is associated with the identification information. The one or more computing devices are used to perform identity verification on the user using the plurality of images, including the first image, and the second image.

deleting, from the plurality of images, an image obtained at a time that is before a predetermined time period.

### Claim 4 (depends on 1)

The method according to claim 1, wherein obtaining the identification information from the user comprises:
obtaining the identification information from a radio frequency identification (RFID) tag or a near field communication (NFC) chip carried by the user.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the performing comprises:
determining whether any image of the plurality of images matches the second image;
in response to determining that a particular image of the plurality of images matches the second image, determining that the user passed the identity verification; and
in response to determining that none of the plurality of images matches the second image, determining that the user failed the identity verification.

### Claim 6

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
while a user is located in a waiting area that is adjacent to and not overlapping with a verification area, obtaining, using one or more computing devices and in real time, a video of the waiting area that does not include the verification area;
extracting, using the one or more computing devices, a plurality of images from the video, wherein the plurality of images comprises a first image of the user, wherein the plurality of images further comprises a first and second face image of the user, and wherein extracting the plurality of images comprises:
extracting a plurality of frames from the video;
identifying, from the plurality of frames, the first and second face image of the user;
determining that a size of the second face image is greater than a predetermined size and the size of the first face image is smaller than the predetermined size; and
in response to determining that the size of the second face image is greater than the predetermined size and the size of the first face image is smaller than the predetermined size;
extracting, from the plurality of frames, the first face image of the user;
storing, using the one or more computing devices, the plurality of images;
while the user is located inside the verification area, obtaining, using the one or more computing devices, identification information from the user;
