NFC Tag message board is an android app that is currently a proof of concept of a localized message system.
( But it could also be useful as a personal reminder system )
It is quite simple, and does the job of reading and writing to any plain text NFC tags. At a minimum you are recommended to use NTAG216 that gives you approximately 800 bytes of writeable memory.
It also has the advantage of being relatively private means of communicating (even if it runs the issue of spoofing), since it is essentially a dead drop system.
There is even an entry on it in n-o-d-e net magazine: http://n-o-d-e.net/post/117867873191/digital-dead-drops-secret-communication-in-plain
* Geo Cache GuestBook
* Ingress Local Message Store
* Personal Reminder System (E.g. place a tag on your desk, and tap to read the latest reminder)
* Reads Plain Text
* Write and prepends a message to a Plain Text Tag
* Message can be either a message, or nickname, or a timestamp only; or a combination of each one.
* UTF-8 support, so can show emoticon.
* Links, email, map address are autolinked
* Static Header Text - So you can keep a short unchanging message on the first line.
* Create a new tag - Easier to get started with this! Just get an empty writable NFC tag!
* For bolding a word or sentence type (" **bold** ") (Note, you need space on both ends.
## Markdownish Syntax:
This is the supported syntax. Can't support full markdown, since this is only a lite hacky implementation. But kind handy for a no frills display that is easy to type on a mobile phone keypad.
# H1 only in first line (Due to technical hacks used)
## H2 headers as usual
*italic* **bold** ***bold_italic***
## Classic List
- list item 1
- list item 2
## Nonstandard List Syntax
- list item 1
- list item 2
## Block Quotes
> Quoted stuff
here is inline `literal` codes. Must have space around it.
Good for ascii art
Or 4 space code indent like classic markdown.
* NFC tags placed outdoor should be of the waterproof/epoxy variety. Otherwise the rain will shortcircuit/kill the onboard NFC chip.
* NFC tags placed on metal needs to be of the variety that supports sticking on metal. The metal would usually interfere with standard NFC stickers.
* Sometimes this app accidentally wipes the tag. A restore button is included just in case.
