Question

Quizplus · Accepted Answer

Before communication between an NFC-enabled smartphone and a tag or another device, the smartphone must identify the capabilities of the other device or tag, such as whether it supports NFC, the type of data it can exchange, and the level of security it provides. This is done through a process called "initialization." Reading the serial number or transmitting clock speed are not necessary for initializing communication. Receiving a reply from all devices within its range is also not necessary as the smartphone only needs to identify the capabilities of the device or tag it intends to communicate with.
