  • Badge Technology: In order to help Google understand which event experiences at Google I/O are well attended and to also ensure the event is safe and secure, Google will utilize both Near Field Communications (“NFC”) and Bluetooth Low Energy (“BLE”) technology (optional). BLE will only be utilized in demo locations around the Sandbox at Google I/O. By registering for Google I/O, you consent to having a badge that utilizes NFC technology as this is mandatory for the safety and security of all Google I/O attendees and staff. If you want your badge to utilize BLE technology, you must explicitly opt-in by checking the box on the registration form related to BLE technology, please note this is not required to attend Google I/O and is completely optional.
  • NFC Badge Technology: NFC is a short-range wireless connectivity standard that uses magnetic field induction to enable communication between devices when they're touched together, or brought within a few centimeters of each other. The NFC chip is embedded inside your badge and is encoded using ITN’s proprietary encoding format. While attending Google I/O you will scan your badge with the embedded NFC chip to ITN’s BCARD Reader application so that Google can understand which event experiences are well attended while maintaining the safety and security of the event. Your individualized data will be accessible by a small team of Googlers and ITN (less than five people) for the purposes of supporting your event registration. Outside of this small team, your information will be reported within Google in aggregate to understand attendance trends and metrics.
  • BLE Badge Technology: BLE is a form of wireless communication designed for short-range use. If you opt-in to a badge that utilizes BLE technology, you will have a Smart Tag either clipped onto the lanyard or stuck onto your badge. This will then allow you to be passively scanned from hubs set up in various demo locations around the Sandbox. This BLE technology will only be utilized when you are in the demo locations around the Sandbox. Google and ITN will track your attendance in Sandbox/demo areas and the data will be recorded in aggregate only. For clarity, neither Google nor ITN will have access to individual location and/or movement data. You may opt out of having your Google I/O attendee badge utilize the BLE technology at any time before the event by reaching out to and at any time during the event by visiting the Help Desk onsite at check-in for Google I/O.
