- sjtgraham 10y agoI bet it's not interactive. Interactivity powered by near field RF is impractical because power is lost when the card is out of range. This would result in some very awkward UX as users have to hold their card close enough to the reader for power while they verify the transaction metadata and enter their PIN.
