I wonder about induction too - could you put a small magnet in
the disk, and use the varying induced fields in the reader
mechanism to generate power?
Contactless smart cards typically have coils in the card and the
iso format/standard is not only thickness but also flexibility even
some proximity (iso 14443) cards have had problem in the past with
flexibiity standards because flex tests would stress the coils in the
plastic and cause the connection to the chip to break.

But, how do they power it?
