1. Metallic materials are interfering with the operation of the RFID reader or RFID/NFC chip. If the RFID reader is attached to a metal housing or if it lies on a metallic .
RFID systems are extremely reliable; some enterprises achieve a 99.9% system reliability on their RFID network, but what happens when an RFID system is performing .
If a generic naive RFID system is used, anyone can read, without restriction, the connection between the product and the tag and obtain information regarding the tagged .
Researchers have designed an RFID chip that prevents so-called side-channel attacks, which analyze patterns of memory access or fluctuations in power usage when a .RFID attacks occur when an unauthorized individual intercepts or manipulates the signals transmitted between RFID tags and readers. There are several techniques commonly used by .When the tag sends its serial number to the reader, the latter requests the unique cryptographic key, which cannot be cloned. A transaction is only authorized if the correct key is received. The private key is stored in the protected memory of the RFID chip and cannot be read from outside. The reader verifies the validity of this digital signature using the public key .
If it is a basic data providing tag, then it can be cloned. If it is a secure tag, it is far more difficult. For secure cards used for payments and authentication, a private key is loaded . Compared to a simple cleartext password, this means that a passive eavesdropper can't discover the shared key. As with the password, the authentication state may be used to .

NFC tags and readers communicate wirelessly with each other over very short distances. Tags store a small amount of data on them that is sent to .ACR1252U is capable of the three modes of NFC, namely: card reader/writer, card emulation and peer-to-peer communication. . It supports ISO 14443 Type A and B cards, MIFARE, FeliCa, and ISO 18092–compliant NFC tags. It also supports other NFC devices with an access speed of .
