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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic device, controller and control method for NFC","description":"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 pr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9820185","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
