I definitely wouldn't want to be in the same room as an active ISO 14443 antenna capable of powering up even low-powered tags/cards from 10 meters. That would be a lot of power! That said, Apple devices use an active amplifier even in card emulation mode (which is why Apple Pay works considerably more reliably at awkward angles than Google Pay does on most Android phones).
- lxgr 2y agoYes, but let's be clear: You have Apple to thank for it. Android has supported HCE-based card emulation and provided access to any app developer out there for a decade now. No special entitlement, certification, or licensing fee required.
