Abstract
An integrated RF card reader includes an integrated RF transmission unit including a Felica chip and a Felica security unit performing a security function that is needed to process a Felica type RF card where an RF function is removed. Since a variety of types can be embodied through a single RF transmission circuit by using the integrated RF card reader, a manufacturing cost can be reduced.
