  3. 2. Near Field Communication Security concerns & applicable security in Android

    Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Filip Bengtsson; Matteo Madrusan; [2020]
    Nyckelord :Near field communication; active NFC; security protocol; security exploit; standard security protocol; NFC attack countermeasures;

    Sammanfattning : Near Field Communication (NFC) is being used more frequent in smart devices, this raises security concerns whether the users information is secure from attackers. The thesis examines the threats that NFC on Android smartphones are exposed to, its countermeasures, as well as existing protocols that ensures the integrity and confidentiality of the users data.

  4. 3. Wireless Body Area Network for Patient Monitoring in Hospitals

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Divya Vinod Kalkotwar; [2016]
    Nyckelord :IEEE 802.15.4; wireless body area network; beacon mode; CSMA CA; NFC; patient monitoring.;

    Sammanfattning : The master thesis is a prototyping project of a wireless body area network (WBANs) for patient monitoring in hospitals. The goal of this project was to study various technologies suitable for wireless body area networks, complete a requirement analysis, design a WBAN suitable to achieve the requirements and to test and evaluate the system against the requirements.

  5. 4. Förenklad hantering av stämpelkort med smartphones

    Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Jesper Westerberg; [2013]
    Nyckelord :Stämpelkort; Webbapplikation; NFC; Förenkling; Smartphones;

    Sammanfattning : Today bonuscards are used widely to encourage customers to return for more purchases. Many of those bonuscards are today made of paper which is negative for the environment and since they are not very valuable they are also easy to misplace. LÄS MER

  7. 5. THE POWER OF TAPPING : An interaction model for implementing NFC in Android applications

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Martin Holeby; Patrik Sandberg; [2013]
    Nyckelord :;

    Sammanfattning : Near Field Communication (NFC) is an RFID-based technology that creates a port between the physical and the digital world through an interaction technique often referred to as tapping; communication is initiated when two interactive NFC-items briefly touch each other. The tapping interaction technique opens up for creation of new types of user interfaces that are compelling to use for both experienced and novice users. LÄS MER
