Setup and Guided Tutorial (Click)

1. Does this Tag require a battery to work?

  • No, NFC tags are powered by the ambient energy of your phone.  They are completely passive and are only activated when a phone is held nearby.  The ambient energy given off by your phone connecting to the cellular tower powers the NFC tag enough to read the data it stores.  Hence, there is no battery, no battery change, no chance of the tag running out of power for hundreds of years.

2. How long does the Tag last?

  • Since a Tag has no battery, its life is nearly limitless. Various Tag types have different estimated lifespans based on the chips inside. However, the chips we are using are estimated to have a minimum lifespan of 250 years.  So if George Washington had tagged the sword he used to cross the Delaware and passed it down, we could hold a phone up to it and see his journal, photos and videos of that event. Wouldn't it be awesome if the tech existed to have done that...we now have the technology to preserve such events.

3.  Can my location be tracked since I put a chip on my Bow or Mount?

  • No, it can not in any way.  The Tag is completely passive and can not be located by devices other than ones a few millimeters away providing it energy.  The location data provided in the "add event" feature comes from your cell phone and is added to the Tag storage, it does not come from the Tag.

4.  Can multiple people add events to my Tag?

  • Only the owner of the Tag can add events.  Friends, family and fellow enthusiasts can view the events you have added by holding the NFC area of their phone up to your Tag.  Once you have added an amazing adventure through "add event", you can also click "share" to post this event easily to your social channels as well.

5.  I've added some great stories and content to my Mount or Bow Tag and I want to pass it down to the next generation, how do I transfer ownership?

  • Each Tag can only have ONE owner at a time, although you can share its rich memories with anyone who wants to view the Tag's content.  However, it is very easy to pass it down or along to a NEW owner at any time.  Touch the Tag with your phone to open the rainf4ll web app and view the history.  From the Rainf4ll.com page, just click "More" then "Transfer".  You will enter the email of the new owner you are passing it to or selling it to.  They will get an email notifying them of the transfer.  Once they accept it and have created a Rainf4ll account, they will be the new owner of the Tag and all its data, memories, history and can start to add their own.  It's that simple.  Pass your heritage and legacies on!
