Abstract: The present invention provides a secure wireless device and a method for secure wireless communication between a secure wireless device and a mobile device using NFC. The devices have a common seed value, which may be provided to the secure wireless device by the mobile device when they are is physical contact. During contact the mobile device sends a pairing request and credentials to the secure device. After the credentials are validated, the devices are paired and can exchange encrypted messages via a suitable wireless interface such as Bluetooth, the messages being encrypted initially based on the common seed value and the encryption key being regenerated by each device after message transmission by the secure device and reception by the mobile device. The secure device stores confidential data, which can be sent in encrypted messages to the mobile device.
