A system, method, mobile communication device and one or more computer programs for an access control system for controlling access to a restricted area. In one form, the restricted area is a parking station. In one aspect, the system includes: a communication system; and a computer program executable by a mobile communication device configured to: receive one or more entry signals from the communication system when the entity approaches an entry point of a restricted area; transfer, to the communication system, an entry request; receive, from the communication system, authorisation data indicative of the entity being granted access to enter the restricted area by an access control system; receive one or more exit signals from the communication system when the entity approaches an exit point of the restricted area; and transfer, to the communication system, an exit request indicative of the authorisation data in order to exit the restricted area.

A method for controlling access to a restricted resource is provided. The method may include receiving, by a cloud server, an identifier from a user device over a long range wireless channel. Further, the method may include comparing the identifier with a plurality of identifiers registered with an access control device. Further, the method may include authenticating the user device based on the comparing and subsequently transmitting a code to the user device upon successful authenticating. Thereafter, the user device may transmit the code to the access control device over a short range wireless channel. Further, the access control device may be configured to provide access to the restricted resource based on receiving of the code. Further, the method may include transmitting the code to the access control device over a long range wireless channel so that the access control device may authenticate the user device.

A system for controlling access to an access-restricted zone in a building includes a transmitting device transmitting a first radio signal, a receiving device for radio signals, a control device and a signal processing device communicatively connected to the receiving and control devices. The signal processing device determines a first channel impulse response based on the first radio signal received by the receiving device and a second channel impulse response based on a second radio signal received by the receiving device. The second radio signal is transmitted from a first mobile electronic device of a first user. The signal processing device determines a degree of similarity by evaluating the first and second channel impulse responses. The degree of similarity indicates how similar the first and second channel impulse responses are to one another. The control device initiates a building action if the degree of similarity meets a specified rule.

A method for controlling access to a restricted resource is provided. The method may include receiving, by a cloud server, identifiers from a user device over a long range wireless channel. Further, the method may include comparing the identifiers with a plurality of identifiers registered with access control devices. A system of control access with mobile and keycard access is also provided with long distance wireless communications between the cloud server and access control devices where the information can be remotely and wirelessly updated in each access control device independantly.

Further, the method may include authenticating the user device based on the comparing and subsequently transmitting a code to the user device upon successful authenticating. Thereafter, the user device may transmit the code to the access control device over a short range wireless channel. Further, the access control device may be configured to provide access to the restricted resource based on receiving of the code. Further, the method may include transmitting the code to the access control device over a long range wireless channel so that the access control device may authenticate the user device.

A system, method, mobile communication device and one or more computer programs for an access control system for controlling access to a restricted area. In one form, the restricted area is a parking station. In one aspect, the system includes: a communication system; and a computer program executable by a mobile communication device configured to: receive one or more entry signals from the communication system when the entity approaches an entry point of a restricted area; transfer, to the communication system, an entry request; receive, from the communication system, authorisation data indicative of the entity being granted access to enter the restricted area by an access control system; receive one or more exit signals from the communication system when the entity approaches an exit point of the restricted area; and transfer, to the communication system, an exit request indicative of the authorisation data in order to exit the restricted area.

A mobile computing device for transmitting token data to a key card reading device having an activation mechanism is provided. The computing device is programmed to receive token data representing access data of a key card, generate a transmission signal representing the access data of the key card based on the token data in response to receiving the token data, and output the transmission signal to the key card reading device. The access data causes the key card reading device to activate the activation mechanism. The transmission signal causes the key card reading device to activate the activation mechanism when the mobile computing device is placed near the key card reading device and the transmission signal is authenticated by the key card reading device.

A method includes performing, by a terminal with an access card, a first relay attack check for the access card in accordance with a local value associated with the terminal and a local value associated with the access card; determining, by the terminal, that the access card has passed the first relay attack check, and based thereon, performing, by the terminal with the access card, an authentication check of the access card in accordance with the local value associated with the terminal, the local value associated with the access card, and a local challenge value associated with the terminal; and determining, by the terminal, that the access card has passed the first relay attack check and the authentication check, and based thereon, validating, by the terminal, the access card.

A reception range varying system includes a vehicle control device and a portable device. The reception range varying system determines whether a position where the portable device exists is within an execution range which enables execution of vehicle control over the portable device, or within a reception range but outside the execution range, and narrows the reception range so that the portable device is positioned outside the reception range while maintaining the reception range at a size equivalent to or larger than the execution range, on the basis that the position where the portable device exists is within the reception range but outside the execution range.

A system for remotely controlling the position of a land vehicle door includes a hand-held communication device such as a key fob having a low-power setting and a high-power setting for wirelessly transmitting low-power command signals and high-power command signals, respectively. Each of the command signals containing command data which identifies a command issued by a pedestrian carrying the hand-held device and identification data which identifies the hand-held device. A mobile communication device is supported on the vehicle for movement therewith and is capable of wirelessly receiving the high-power and low-power command signals. Control logic is coupled to the devices. The hand-held and mobile communication devices automatically transmit and receive, respectively, the low-power command signals as long as a pedestrian carrying an authorized hand-held device is within a predetermined short range of the mobile device.

In a gate pass management system, a first reception unit having a first reception range receives a first RF signal including identification information of a mobile device. In the gate pass management system, a second reception unit having a second reception range, defined to be a range located closer to a predetermined area than the first reception range is, receives a second RF signal. In the gate pass management system, when the second RF signal is received after the first RF signal has been received, a decision is made that the mobile device be currently located within the second reception range.
