“…In the literature, researchers have proposed different ways for synchronizing the read and write cycles of RFID devices. Such as, in [61] authors perform synchronization of densely populated RFID readers (e.g., in warehouse) via a centralized command center. Similarly, [62] uses a rotating disk with LEDs to determine the order for performing the read/write operations on multiple NFC tags and readers/writers.…”

Near Field Communication (NFC) is a prominent short-range, contact-less communication technology, which is rapidly getting popular in modern smart devices. For communication between two active devices via NFC, applications generally choose the peer-to-peer operation mode. In this paper, we exploit the possibility of using the NFC read/write mode, designed primarily for unidirectional data transfer from an active NFC reader to a passive NFC tag, for bi-directional half-duplex communication between two active NFC devices. The advantages of using the NFC read/write mode include low protocol overhead and permitting different data formats. However, the challenges are avoiding the reader collision problem, maintaining a secure session, and completing all transactions in an acceptable time frame. In this paper, we address the above challenges and propose a methodology for efficient communication between active NFC devices using NFC read/write mode. To evaluate the scheme, we design a secure Multi-Factor Authentication (MFA) system that requires bi-directional communication for mutually authenticating two NFC devices. The proposed methodology is experimentally verified using NFC-enabled Android smartphones and a Kerberos server as the third-party authenticator.

“…Wireless intelligent electronic card to wake up wake-up signal to launch, the design required to send a strong signal of directional antennas, also asked the miniaturization of antenna size. Abroad in order to prevent the parking lane between the wireless wake-up signals interfere with each other, be able to use the microwave absorption characteristics of the material into the isolation plate, then the use of these isolation plate separation between the lanes, but the wake-up signal when the leak situation has happened, but the cost of this design is more expensive, but also near the lane leading to the wireless smart card being erroneous wake-up [1]. In this paper, the design of four units of rectangular micro-strip antenna array of the array element in the space formed by the direction of interference field at certain mutual superposition or, in some directions offset each other, can produce some of the specific direction of the corresponding maps, thereby enhancing the gain [2], to improve the direction, using a quarter-wavelength rectangular micro-strip antenna array element.…”

Wake-up signal reception sensitivity and the antenna has a close relationship, from the parking lot of the practical needs of communication, as well as the works of Wireless Intelligent Electronics Card System structure requirements, using a quarter-wavelength design four rectangular micro-strip antenna array modules. Wireless intelligent electronic card to participate in the car parks are long-distance communication systems RFID identification system, four modules of rectangular micro-strip antenna array to send wake-up signal is highly directional, and four units of rectangular micro-strip antenna array to send the signal electron can wake up the wireless smart card job, and avoid the region other than the wireless smart card electronic interference.

Recently, RFID system has become popular and has been growing rapidly. Due to using many readers in limited area, RFID reader collision problem occurs when the reader is interfered with the signals from neighbor readers or other devices. Even if 50 channels are available in North America, 15 channels in Europe and 25 channels in Korea are available. Moreover, in the future, if many mobile (cellular) RFID readers might be used in limited area simultaneously, the number of channels is not enough, and the collision problem might be more serious. Therefore, this paper proposes an advanced RFID system with a channel holder and dual reader sensitivities/reduced reader output power. © 2007 Wiley Periodicals, Inc.
