In an example implementation, a portable computing device may alternate between scanning for tactile input, such as a user's finger on a trackpad, and scanning for wireless input, such as a near field communication (NFC) signal. If tactile input is received, the portable computing device may stop scanning for wireless input while the portable computing device continues to receive the tactile input. When the portable computing device stops receiving the tactile input, the portable computing device may return to alternating between scanning for tactile input and scanning for wireless input. If wireless input is received, the portable computing device may stop scanning for tactile input while wirelessly communicating with the device from which the wireless input was received. When the portable computing device is finished wirelessly communicating with the device, the portable computing device may return to alternating between scanning for tactile input and scanning for wireless input.
