The easiest way to clone Mifare NFC Classic 1K Cards is by using an Android smartphone with NFC capabilities. That’s right, your cellphone can be used to compromise the security of a company if they are using these types of cards (RFID security system).
This gate can detect the movement direction of an RF tag by judging the difference between the two passing times at each sensor. For example, because the RF tag moves from the left side to the right side in the case of Fig.1, sensor 1 detects it in advance of the detection at .It is important for RFID gate to identify the several RFID readings such as movement type and .This gate can detect the movement direction of an RF tag by judging the difference between .In this paper, a new method of tag movement direction detection using the difference of .

In this paper, a new method of tag movement direction detection using the difference of passing time of two antennas without external expensive sensors is proposed. Some experimental results of this method are also shown and its feasibility is proved. We implement our method using an Impinj R420 RFID reader, four 8dBi directional antennas and Impinj H47 RFID tags. The RFID reader is configured as the fastest RF mode (Max Throughput, Dual target and Session 0) to improve read rate.Figure 3: Intellident UHF RFID reader[14] 5.4 Direction of movement Direction of movement estimates the direction the tag is moving in. The most widespread solution consists of installing photo eyes or electric eye sensors. Another solution is installing another set of antennas, further down the portal. Some implementation rely
A simple and accurate movement direction estimation method to determine the movement direction of tagged object through a Radio Frequency Identification (RFID)-based system, using the variation tendency of the signal phase received by two antennas is proposed. A new RFID reader from U.K.-based technology company PervasID is offering bidirectional detection of moving tagged items with what the company claims is more than 99 percent accuracy. The Flow Ranger is designed not only to read tags in highly dense environments, such as one containing a pallet loaded with tagged goods, but also to identify . For RFiD readers, Circular polarization antennas allow the reader to read tags in various orientations within the sensing range of RFID reader. This does not mean the RFID is generating RF power from all directions like a dipole antenna.
