I decided to lockout my #Bitcoin & #Ethereum apps by #NFC. I dropped the info on the NFC sticker tags, locked the apps down, set the bridge for NFC (physical response) for each app. Now what to do with the tags...have you ever seen the key chains that hold a plastic bottle (like 20 once or less)?

(#BTC)
------------------------------------------------------------
(#ETH)
------------------------------------------------------------
My Process:
--> I double layered the tags with acrylic tape.
--> I glued each protected tag to a plastic disc (approx 1/16 inch).
--> I layered the tag & disc inbetween acrylic tape.
--> I glued the two disc combos together.
--> I glued the set into the hole to hold the plastic bottle (on the key chain mentioned earlier).
--> I glued remaining holes and openings.
------------------------------------------------------------
This has a couple bugs:
The tags are so close together, if the device (my phone) reading the tags is directly upon the tags, it'll only read one tag. My tag writer allows an NFC hierarchy for multi-tagging, then I locked one to the other (I mean one will trump the other during those kind of read). So, to use these correctly, you have to hold the decide about half an inch from the tag to read that tag. The last bug is during the "multi-tagging" & attach system. If the attach protocol is returned the tag returns an error(void) instead of the tag(hexcode). Keep in mind, the attach(tag#ID) is only on the tag that gets trumped so, when it farted trumped the code from the tag gets lost in translation during the I-net pass.

Give it a try or give it a go on something else, like a fingernail...
