The future of live events is digital. Soon, your tickets, how to pay for drinks, and even your ability to share experiences on social networks can all be done with your wrist.

Radio frequency identification (RFID) wristbands will be unveiled at many festivals and events this summer to replace NFC smart phones.

Most RFID wristbands contain short-distance (usually 3-5 cm) passive tags, do not require batteries, and only supply power when they are close to or "tap" the RFID reader.

Opinion: Is NFC a killer application? No chance to flip
When the RFID wristband is detected, the reader "stirs" the magnetic field generated by the coiled antenna inside the tag. The tag then uses this kinetic energy to "power up" and send the data (stored in the tag's memory) back to the reader.

The tag in the RFID wristband can be personalized with someone's personal data (for example, the data is directly stored on the chip itself), or it can be used as a "key" to access a personal data security database.
