The wireless technology that allows a customer to connect to a payment terminal in a store with a smartphone for transactions is NFC. NFC* (Near Field Communication) is a short-range wireless technology that enables communication between devices when they are brought within a few centimeters of each other. This is the technology used for contactless payments, where a smartphone is tapped or held close to a payment terminal. Bluetooth* is used for short-range data exchange, often for connecting peripherals like headphones, but not typically for direct payment terminal interactions. GPS* (Global Positioning System) is used for location tracking and navigation. Wi-Fi* is used for connecting to local area networks and the internet over a longer range, but it is not the direct technology for smartphone-to-terminal payment communication. The correct option is NFC.
