RFID wristbands can be seen in various modern festivals and events. They simplify the way to pay and share experiences to social media.
Most RFID wristbands contain short-distance (usually 3-5cm) passive tags, do not need to bring their own batteries, just approach or touch the RFID reader to get energy. When the reader detects the RFID wristband, it will automatically activate the magnetic field of the coil antenna in the tag to supply energy to the tag, thereby transmitting the data in the tag to the reader.
The tag in the RFID wristband can be directly written into the information, or used as a key to enter the personal security database.
RFID wristbands have been used in festivals such as music festivals all over the world to provide tourists with fast track, cashless payment and social media interaction. After purchasing tickets online, users can choose to bind RFID wristbands at music festivals to their Facebook and Twitter accounts. In this way, users can tweet, share or "like" their favorite activities during the event.
With the development of RFID technology, more and more festivals use RFID wristbands. It is estimated that almost most tourists in the world have used RFID wristbands so far. And there are more and more RFID wristbands for sale.
Although NFC on smart phones can be used as a substitute, the problem is that not everyone has an NFC phone, and RFID wristbands can be used by everyone. Another problem is that the mobile phone needs to have its own power supply, and there may be a dead battery. However, there is generally no place for charging in the festival venue. If the mobile phone is powered off and turned off, it is impossible to use electronic wallets, e-tickets or social media on the mobile phone.
As of now, data shows that tens of millions of Facebook "likes" and hundreds of millions of contactless transactions have been generated by RFID wristbands. We can look forward to the widespread use of RFID wristbands in the near future.
