But beyond that, the retailer already saw your face when you walked in, already saw it at the point of sale, already tracked you as you traveled the store via WiFi, already saw the BT/WiFi profile of your rotating MAC address device as it only obfuscates, and in some cases, already had your phone join their WiFi network via EAP-SIM through your carrier, already scanned your license plate with Flock in the parking lot, and already saw your club/discount/points card number at the point of sale, so they already associated you with yourself.
Tap-to-pay also sets up so all your transactions, on-phone or not, are captured by the handset manufacturer for further resale of metadata.
