  • RF probe alignment with passive tag
    Patent number: 9317796
    Abstract: A passive tag embedded in a package includes multiple conductive coils. A first coil receives radio frequency (RF) energy used to power the tag. Additional coils receive and/or transmit data signals, clock signals, and carrier signals. The RF energy and other signals may be at different frequencies. An RF probe includes a first coil to emit the RF energy to power the tag. The RF probe includes additional coils corresponding to the additional coils in the tag. The RF probe may turn off the RF signal used for power during communication. The RF energy may be rectified to provide DC power to circuits in the tag, or may be used directly for adiabatic circuits. The RF probe and the package may have complementary shapes to facilitate alignment of the coils.

  • SMARTCARD BASED MULTIFACTOR BANKING AUTHENTICATION
    Publication number: 20150381613
    Abstract: A multifactor authentication (MFA) enforcement server provides multifactor authentication services to users and existing services. During registration, the MFA enforcement server changes a user's password on an existing service to a password unknown to the user. During normal usage when the user accesses the existing service through the MFA enforcement server, the MFA enforcement server enforces a multifactor authentication enforcement policy.
