What is the function of NFC and how should NFC be used?


Near Field Communication (NFC), a short-range, high-frequency radio technology, operates at a distance of 10cm at 13.56 MHz. Its transmission speed is available in 106 Kbit/sec, 212 Kbit/sec or 424 Kbit/sec. NFC uses both active and passive reading modes, combining inductive reader, proximity card and peer-to-peer functionality on a single chip, enabling identification and data exchange with compatible devices over short distances.

According to the characteristics and advantages of NFC technology itself, the basic form of NFC-oriented business mainly has the following characteristics.

  1. Short: short communication distance, NFC-based communication distance is generally within 10cm, generally within the reach of human hands.
  2. Frequency: as a short-range wireless communication technology, although it is not a new technology, but in the past two years at home and abroad has been the rapid development of the mobile payment as a representative of the NFC application is gradually deepened into people’s daily lives, so the use of NFC business-oriented will become more and more frequent.
  3. Fast: NFC technology-based information transmission belongs to the triggered information transmission, although the transmission rate is not high, but often require information interaction in a very short period of time, so different from other communication services, NFC-oriented business needs to be processed quickly.

How NFC tags can help owners find lost pets faster?


One of the first things most people do when they find a lost pet is check the pet’s collar tag, which usually has the owner’s name and phone number on it. However, the numbers and letters on the collar tag become blurred and illegible due to prolonged wear. Using QR code technology or pet tags with NFC capabilities, users can scan the QR code printed on the front of an NFC pet tag with their smartphone to access more data about their pet on their mobile phone.

First, the user creates an online profile of their pet, including information such as name, breed, age, medications and allergies, as well as contact information for multiple emergency contacts. Users are then provided with a QR code that embeds their pet’s profile on a tag, and pet owners are required to pay a monthly or annual fee for the lost pet search service, either for their pet or their family. Good Samaritans looking for lost pets can simply access the tag to find information about the pet owner.

The biggest challenge in using this short-range transmission version of RFID technology is incorporating the technology into a metal tag so that the tag can reliably store and transmit data. As a result, the NFC chip is encased in thick epoxy resin, and the NFC epoxy pet tag has a metal ring for added durability.
