Abstract
Contactless services, applications, and/or transactions can be performed between a mobile terminal and a contactless reader even when the mobile terminal battery power is found to be insufficient or if there is some other problem with the battery. Current is induced from electromagnetic (EM) fields or radio frequency (RF) signals detected near the mobile terminal such that sufficient power can be momentarily and/or temporarily used to access information from a smart card or other components within the mobile terminal, and allow user interaction via the contactless reader.
