MADRID, SPAIN / ACCESSWIRE / / HASHWallet, an innovative hardware wallet designed to safeguard crypto-assets in the shape of a convenient smart card – has started its crowdfunding campaign on.
Maybe a bitcoin library that also provides a HAL for any hardware RNGs or ECDSA accelerators would be the best way to go. Maybe Maxim MAXQ1050.
Credit card dimensions, but 4 mm thick. It uses a 128×64 OLED display. Also includes a small battery, only 65 mAh, enough for probably about 1-2 hours of powered-on time before needing to be recharged. I may consider E-ink instead for lower power.
I think adoption is critical, also that as NFC 3D printed bitcoin tags can be used as "notes", in the real world, for a newcomer, the impact that this Bitcoin is a real thing and not another "cool" hipster thing / app to download and soon forget. Bitcoin is revolution. Not many people know Bitcoin at the moment, even if there’s investment, even if there’s (mostly bad) news. They don’t trust.

Essentially, Bitcoin is a form of cyber-currency enabled by blockchain technology.
July 2011 – First NFC Bitcoin transaction carried out.
Use an NFC Tag for my public key (so others can tap it and send me coins) I saw a video that this can be done but he doesn’t explain how. He wrote some code where you scan the tag and it pops up and everything ready to send. Just like how a QR code works except this is done with an NFC Tag. I’m fascinated by Bitcoin and NFC and just trying to come up with new fun ideas on using the two. 23.
