A 2D barcode encryption method, a 2D barcode transmission system and a storage medium are provided. The method includes: generating a first character string of a first numeral system based on information of a user; converting the first character string into a second character string of a second numeral system using a preset codebook, wherein the preset codebook is updated according to a first preset period, and a base number of the second numeral system is greater than that of the first numeral system; and generating a 2D barcode using the second character string. Security of access control for a shared space may be improved.

A reader configured to perform dual-factor authentication is provided. The reader is configured to analyze credential data as well as event-based user inputs. The event-based user inputs are received in response to the reader presenting one or more events to a user and monitoring the user's reaction thereto. Utilization of an event-based user input enables the reader to perform dual-factor authentication without necessarily being provided with a keyboard or other advanced user input device.

A settlement processing system S is configured to perform a settlement process for a product picked up by a user based on information for settlement of the user, when closing of a door 12 of a vending machine 1 is detected after opening of the door 12 is detected. In addition, the settlement processing system S is configured to perform the settlement process for the product picked up by the user based on the information for settlement of the user, in a state in which the closing of the door 12 of the vending machine 1 is not detected after the opening of the door 12 is detected, when the state in which the user has moved from the vending machine 1 is detected.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex. The lagoon includes a surf feature and surrounding the lagoon are entertainment, educational, sports, and commercial facilities. The complex has a controlled public access and provides the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon having a surf feature. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

The specification discloses a system and a method for realizing identity identification based on a radio frequency identification technology. The system comprises: a radio frequency detector on the ground and configured to detect radio frequency tags and send, when a radio frequency tag is detected, information carried in the radio frequency tag to a controller; a camera configured to collect a face image and send the collected face image to the controller; and the controller, configured to: determine, according to the information, a first identification of a user corresponding to the radio frequency tag, determine, according to the face image, a second identification of the user, and control a turnstile to allow the user to pass through when the first identification of the user and the second identification of the user match.

The system of the present invention is comprises of one or more door lock units, a data exchange system, and a clerk user interface. The door lock units are mounted to the cooler doors and prevent the doors from opening to allow access to the alcoholic products without authorization. These door lock units include a mechanical locking mechanism, an identification scanner/reader, and a display. The door lock units receives power from a power supply (with a back up power supply standing ready) and communicates wired or wirelessly with a data server and router combination. The data server and router combination also communicates with a clerk user interface, which may be in the form of a tablet, smart phone, laptop, or other computing device.

An electronic certificate transmission method, apparatus and device are provided. In a process of obtaining a business service, a first user may perform, using a terminal device through short-range communication, information communication with a terminal device used by a second user to obtain user information of the second user. Then, the first user may send the obtained user information of the second user and identifier information of an electronic certificate of the first user to a business server providing the electronic certificate. The business server may check the user information of the second user and deliver the same electronic certificate to the second user after the verification succeeds, thereby achieving sharing of the electronic certificate.
