An electronic device for near field communication (NFC) device includes a front end unit configured to communicate with an external reader/writer device, the front end unit including a first memory adapted to store a check identifier, the check identifier configured to match one or more first identifiers, and a processing unit including a second memory configured to store one or more applications and one or more first identifiers, wherein a first identifier is assigned to one or more applications.

Electronic device, system and method for NFC

An electronic device, for example for near field communication (NFC), includes a device host including an operating system (OS), a trusted execution environment (TEE), and a near field communication (NFC) controller configured to enable communication of the electronic device with other devices. The NFC controller is coupled to the device host by a data channel for data exchange and a control channel for control information exchange, and the control channel is provided between the TEE and the NFC controller.

Electronic device and communication method for NFC

A portable electronic device () with a NFC (near field communication) unit () is switchable between an active mode and a passive mode. A motion sensor unit () records a motion of the portable electronic device (), and outputs a motion signal descriptive for the recorded motion. A processing unit () analysis the motion signal to detect a first predefined motion pattern including an acceleration and a deceleration phase. The NFC unit () is switched into the active mode upon detection of a first predefined motion pattern descriptive for an NFC touch gesture.

Portable electronic device and operation method for establishing a near field communication link

An electronic device for near field communication (NFC) includes a processor including one or more applications and a controller controlling NFC communication between a reader/writer device and the processor. The controller includes a communication unit that exchanges communication between the external reader/writer device and the processor. A parser parses communication exchanged between the reader/writer device and the processor. The parser is configured to detect a predetermined setting of a response code within an authentication response sent by the processor in response to an authentication request received from the reader/writer device, the predetermined setting indicating that an application of the processing unit is in an authenticated state. A further controller controls the communication unit not to respond to an anti-collision request received from the reader/writer device and/or not to forward an anti-collision request to the processor if the anti-collision request is directed to an application in an authenticated state.

Electronic device, controller and control method for NFC

A method for providing data on the Internet, comprising calculating, using a microprocessor, a value of a predetermined function for said data, wherein the value depends on the data, determining, using said microprocessor, a uniform resource identifier including said value, and storing, at a resource on the Internet, said data, wherein the resource is accessible by using the uniform resource identifier. Further, a method for accessing data on the Internet is provided, comprising retrieving said data from a resource in the Internet by using a uniform resource identifier, determining, using a microprocessor, a part of the uniform resource identifier, the part corresponding to a value of a predetermined function, calculating, using the microprocessor, a further value for said data based on said predetermined function, wherein the value depends on the data, and determining, using the microprocessor, the integrity of said data by comparing said value and said further value.
