NFC vs BLE
NFC tags are passive and need no battery, connecting at touch range in under 100 ms. BLE requires a battery, operates up to 100 meters, and supports continuous low-power streaming. They complement each other: NFC handles tap-to-pair while BLE maintains the ongoing connection.

Use NFC for zero-power tags and instant tap-to-connect; BLE for continuous streaming, beacons, and wearable sensor applications.
