“…The possible destruction of RFID transponders and cards by a strong magnetic field with an intensity of more than 12 A/m is mentioned in [49]. The studies [50,51] deal with the tests of 125 kHz and 13.56 MHz RFID transponders in the strong magnetic field of MRI (magnetic resonance imaging) equipment. The paper [52] states that the damage of animal RFID transponders is almost certain when the animal crawls under a wirelessly charged vehicle where the magnetic field intensity is about 10 kA/m.…”

This paper analyses the possibility of damaging and destroying an identification chip of the Mifare type in a frequently used contactless identification card of size ID-1, following the standard ISO/IEC 7810 (i.e., with dimensions 85.60 × 53.98 × 0.76 mm), using the magnetic field of an adjacent conductor in which a current pulse of a defined shape and amplitude is flowing. For analysis purposes, the nonlinear current–voltage characteristic of the Mifare chip voltage limiter was measured and approximated, and the mutual inductance of the straight conductor and the rectangle coil antenna in the card was calculated. Next, a mathematical analysis was conducted based on the description of the equivalent electrical circuit by the differential equations. The results of the mathematical analysis were verified by a simulation in the free simulation software Micro-Cap 12. The peak value of the current pulse that can damage the Mifare chip was measured by a combination wave generator. Based on these measurements and the chip characteristics, the energy capable of destroying the chip was calculated. The characteristics of chip damage were determined using a comparison of the resonant characteristics of undamaged and damaged RFID cards with Mifare chips.

The purpose of the study was to determine the efficiency and costs of energy biomass transportations, when using a conventional monitoring system linked with Radio Frequency Identification (RFID) technology. In the study, truck-specific transportation monitoring was carried out with the help of a real-time web-based monitoring system. Both smart phones and reader gates were used for data transfer into the system with a wireless Internet connection. The experiments were carried out along the forest chip transportation from the forest roadside storages to the power plant by using either traditional solid-frame trucks or a truck with interchangeable containers. All the delivery containers were mounted with RFID tags. Afterwards, the statistics of the loads and the delivery performance ratio of the transportations were analysed. Additionally, the cost structures for the alternative truck and trailer combination were analysed and their unit costs were determined. Also, the functionality and the reliability of the real-time monitoring system were examined as a part of the demanding roadside chipping chain. The total number of the loads was 68 during the follow-up period. The container truck system was found to be as cost-efficient as the solid-frame truck systems. This paper demonstrates that RFID enables the tracking of the trucks on a real-time basis through the delivery chain, and that the data can be used to analyse the vehicle-specific time usage and the unit costs of deliveries.

“…Literature [15,16,[17][18][19][20] related to the use of RFID in MRI environment have indicated that it was safe to use passive RFID tags or passive RFID implants operating at certain frequencies in several MRI environments. None of these studies reported the malfunction of the device except one where one of the tested implants got deactivated [18].…”

We evaluated certain issues related to magnetic resonance imaging (MRI) coupled with the use of active 2.5 GHz radio frequency identification (RFID) tags for patient identification using low field (0.3 T) MRI and computed tomography (CT) scans. We also investigated the performance of the RFID reader located outside the MRI room by considering several factors. A total of ten active RFID tags were exposed to several MRI sequences and X-rays of CT scan. We found that only card type active RFID tags are suitable for patient identification purpose in MRI environment and both wristbands as well as card tags were suitable for the same in CT environment. Severe artifacts were found in the captured MRI and CT images when the area of the imaging was in proximity to the tags. No external factors affected the performance of active RFID reader stationed outside the MRI scan room.
