What is NFC tag? An NFC tag is a small integrated circuit consisting of a copper coil and some amount of storage. Data can be read or written to this tag only when another NFC device is brought near it because it doesn’t have a power source. The proximity of the NFC device induces power in the tag and enables data transmission. What is an NFC Reader？ Any powered device that has its own NFC coil (like a smartphone or tablet) can act as an NFC reader. The reader device uses its battery to generate an electromagnetic field, which powers...

The key distinction between RFID and NFC lies in their transmission ranges — the former is often used over longer distances. For example, some regions automatically collect road tolls through RFID. Tags are usually affixed to vehicle windshields, allowing you to drive past toll booths at low speeds. Communication can take place over even longer distances (think a hundred feet or more) if the RFID tag is equipped with a power source. NFC, however, only has a maximum range of a few centimeters, at most. And in most smartphone-related applications, you’ll find that the software will only initiate communication if...

Most smartphones have Near Field Communication, or NFC technology, built in these days. If you’ve ever used a mobile payments app like Samsung Pay or Google Pay, you already know how NFC works. In a nutshell, it is a proximity-based wireless communication standard. Unlike Wi-Fi or Bluetooth, however, NFC interaction is limited to an extremely short range. Besides smartphones, you can sometimes find NFC on tablets, speakers, collectibles, and even gaming consoles like the Nintendo Switch and 3DS. Even though NFC may seem a bit lackluster on paper because of its short wireless range, it’s still a convenient feature that many of us...

Twisted-pair network cables (commonly referred to as network cables) are further divided into multiple categories based on their performance and standards, including Category 5 (Cat5), Category 5e (Cat5e), Category 6 (Cat6), Category 6a (Cat6a), Category 7 (Cat7), and Category 8 (Cat8). Each category of network cable has its own specific transmission rate, bandwidth, and maximum transmission distance. Network cable type classification Category 5: Supports 100 Mbps with a maximum transmission distance of 100 meters. Category 5e: Enhanced Category 5, supports 1000 Mbps, also with a maximum transmission distance of 100 meters. Category 6: Supports 10 Gbps up to 55 meters,...
