Abstract
The invention provides a method for ensuring a secure NFC functionality of a wireless mobile communication device comprising the steps of detecting the charge state of a first energy source () which supplies the voltage for operating the wireless mobile communication device (S); switching off the first energy source and switching on a second energy source (), if the detected charge state of the first energy source () falls below a threshold (S); detecting the charge state of the second energy source (), if an external NFC signal is received (S); charging of the second energy source via voltage induced by a received NFC signal to allow at least one secure NFC transaction, if the detected charge state of the second energy source () is below a threshold (S). Furthermore the invention provides a wireless mobile communication device having a secure NFC functionality, which is always ready for operation of at least the secure NFC functionality.
