Abstract
A communication apparatus includes a first RF tag which performs communication using electromagnetic waves in a first frequency band; a second RF tag which performs communication using electromagnetic waves in a second frequency band different from those in the first frequency band; a storage unit having a shared area accessible from the respective RF tags; and a power controller which generates power for driving the first RF tag and the storage unit using the first frequency band electromagnetic waves and supplies the generated power to the first RF tag and the storage unit, and which generates power for driving the second RF tag and the storage unit using the second frequency band electromagnetic waves and supplies the generated power to the second RF tag and the storage unit.
