An authorized user may be provided access to a service only when a wireless token assigned to the user is in the proximity of a computing device. A user's credential may be stored on an RFID token and an RFID reader may be implemented within a security boundary on the computing device, Thus, the credential may be passed to the security boundary without passing through the computing device via software messages or applications. The security boundary may be provided, in part, by incorporating the RFID reader onto the same chip as a cryptographic processing component, Once the information is received by the RFID reader it may be encrypted within the chip. As a result, the information may never be presented in the clear outside of the chip. The cryptographic processing component may cryptographically encrypt/sign the credential received from the token.
