Touchanote can be used by anyone with an NFC-enabled mobile phone running on Android. The application has been developed specifically for the Samsung Nexus S. As additional NFC Androids become available, the app will be updated to ensure proper formatting and compatibility with each device. In addition to an NFC phone, Touchanote users need to procure NFC tags prior to using the app.
NFC tags are small integrated circuits designed to store information that can be retrieved by NFC-enabled devices like the Samsung Nexus S. They are small circular or square-shaped stickers, and are about the size of a large coin.
Touchanote supports NFC Forum-endorsed Type 1 and Type 2 tags, such as MiFare Ultralight C tags. Both types are re-write capable, or can be locked to secure content.
Yes, tags are encrypted upon being written. To review the content stored to a particular tag, a mobile phone must be logged in to the Evernote account that created that particular note. Your tags are protected with the same level of security as your Evernote account.
