A Research Exploration on Near Field Communication Technology

track the target once it is attached on an RFID tag. Passive tags are used to attach on the target object because they are much cheaper, long lived, lightweight and have a smaller foot print. The reader can communicated with host computer through RS232.

The RFID technology consists of three kinds of tags i.e. active RFID tags, passive RFID tags, and battery

The exact definition of Near Field Communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 2in of each other. For example, if I have an iPhone specifically it will connect to the Internet and can exchange data with online services. Different providers such as AT&T Mobility, Verizon Wireless, T-Mobile USA and even Apple have joined in this new interesting way to handle their e-pays.

Solution: Extremely secure channel should be setup between the devices which must have secure shell for the private network. Some NFC enabled devices have capability to listen to the RF signals on the NFC network. When an attacker attacks through a RF device, the differences in RF signals are detected by the NFC transmitter and it stops data transmission (Haselsteine and Breitfuß).

Near field communication (NFC) is an ability available in most modern-day cell phones that allows the device to connect

cards because of the new technology such as Bluetooth, RFID, infrared or NFC. This means that

NFC technology is required to use digital wallet credit card payments for purchases at the check-out counter or for online purchase. There is a passive tag in your credit card that is activated when it comes within 10cm of an NFC initiator device. The NFC initiator is the POS (point of sale) or check-out counter card reader in the store. Most smart phones use NFC so your phone can act as your credit card as soon as you set it up and store the information from your card. Once your phone is set up, all you need to do is hold your phone within 10cm of the same card reader at the store and it will pay for the purchase just like your card.

In a typical RFID system, individual objects are equipped with a small, inexpensive tag which contains a transponder with a digital memory chip that is given a unique electronic product code. The interrogator, an antenna packaged with a transceiver and decoder, emits a signal activating the RFID tag so it can read and write data to it. When an RFID tag passes through the electromagnetic zone, it

NFC is a wireless communication interface, it is obvious that eavesdropping could be an issue. This is an attempt to intercept the NFC transmission data communication (e.g. NFC proxy). When two devices communicate via NFC they use radio frequency (RF) waves to talk to each other. An attacker can use an antenna to also receive the transmitted signals. Eavesdropping occurs when the attacker intercepts communication between an Radio Frequency Identification (RFID) token and an authorized reader. The attacker does not need to power or communicate with the token, so he is able to execute the attack from a greater distance than is possible for skimming. In addition, an eavesdropping attack occurs when an attacker can recover the data sent during a transaction between a legitimate reader and a token, which requires the attack to be set up near a likely target. The attacker needs to capture the transmitted signals using suitable Radio Frequency equipment before recovering and storing the data of interest.

Starting now there are NFC chipped cards (e.g. Barclays/Shellfish and Stadium Cards) which can get ready little portions with a 'touch and go ' recognition structure. More credit and check cards will become chipped and fit for using NFC based portion schemas. More shops, excursion goals and portion spots should apply RFID/NFC card portion wanders. This could moreover be joined in cell phones – joining as a Mastercard. These could then moreover become modified, evacuating all physical operations (no convincing motivation to touch and go, basically enter).

It uses the mesh topology for transmitting data. This way it offers a secure way for communicating wirelessly with a number of other such devices.

NFC can operate in two different modes; it is an active and passive. An active device generates its own radio frequency (RF) field, where as a device in passive mode has to use inductive coupling to transmit data. Mobile phone such as battery powered devices act as in passive mode. In contrast to the active
