The future of live events is digital, and soon, your ticket, the way you pay for drinks and even your ability to share the experience on social networks, could all be done with a tap of the wrist.
Radio-frequency identification (RFID) wristbands are set to feature at many festivals and events this summer as an alternative to the NFC smartphone.
Radio-frequency identification (RFID) wristbands are set to feature at many festivals and events this summer as an alternative to the NFC smartphone.
Most RFID wristbands contain short-range - typically 3-5cm - passive tags and don't require batteries, but instead, are powered when placed near or 'tapped' against an RFID reader.
When detecting an RFID wristband, the reader 'agitates' a magnetic field created by a coiled antenna within the tag. The tag then uses this kinetic energy to 'power-up' and send data (held within the tags' memory), back to the reader.
The tags in RFID wristbands can either be personalised with someone's profile (e.g. data is held directly on the chip itself) or they can be used as an access 'key' to a secure database of personal data.
