Why do only a few cell phones support NFC technology?

Low transmission capacity
High transmission capacity
Medium transmission capacity
Non transmission capacity

The correct answer is: Low transmission capacity

The option indicating low transmission capacity is the correct answer because Near Field Communication (NFC) technology is designed for short-range communication, typically requiring devices to be within a few centimeters of each other for effective data exchange. The transmission capacity of NFC is limited when compared to other wireless technologies like Bluetooth or Wi-Fi, which is primarily due to its intended purpose of facilitating quick, secure transactions and data exchanges without the need for extensive bandwidth. Additionally, NFC's low transmission capacity means that it is often employed for specific applications such as contactless payments, pairing devices, or sharing small amounts of data. This limitation contributes to the relatively few devices that incorporate NFC technology, as manufacturers must evaluate whether the benefits of including NFC align with consumer needs and device capabilities. Other options referring to high, medium, or non-transmission capacities do not accurately reflect the nature and operational characteristics of NFC technology, which specifically thrives on low capacity secure transactions rather than high data throughput.
