Most of these devices are Smartphones, Personal Display Assistant having connectivity based on different wireless connectivity protocol. The common wireless connectivity protocols are BT/BTLE and Wi-Fi. The connection to BT/BTLE and Wi-Fi devices requires the user to follow connection and pairing steps before they can be used for communication. Sometimes it take more steps to connect to these technology and sometimes the password is too cryptic to type without any error. Near Field Communication passive tag provides solution to the above problem and it can be used flawlessly to do the pairing and connection. The NFC forum talks of data structure format for different data types such as Bluetooth Handover message, Wi-Fi handover message, SMS, text etc. This creates a use case where it appreciated to have a NFC Tag with a bigger EEPROM so that different data structures can be put in single tag and the cost can be saved.
