CONCLUSION
• Touch-driven approach is relatively accurate in inferring user intent.
• the usability of touch-driven interaction using NFC is better than QR code-based or voice-based interactions, since the touch action is intuitive, and can be detected quickly, requiring no pre-configuration or setup.
• In this way once the devices are linked up using NFC, they can exchange information using wireless protocols such as WiFi and GPRS remotely.
