I used NFC TagWriter by NXP.Any writer that will write URI tags should work however.After that it is really very simple.If you are using an android wallet, open this first can copy the wallet address you wish to use.Open up the tagwriter, select "Create, write, and store" Press: New - define a new NFC data set Scroll down and select URI (not file URI) Enter description In the URI field enter this: bitcoin:[your wallet address here] Make sure there is no spaces, and click next.bitcoin variantsOn the write options screen that shows next you can leave everything as is, and click next.buy bitcoin achWrite the tag You can add more options if you like following this format: bitcoin:

Users can store their digital money on a device – a smartphone for example – tap a point-of-sale (POS) terminal and their payment will flow through the connection, no wallet required.The Sigsafe tag provides this same functionality, but with bitcoin.Starting off, Peter imagined: “Something [users] could buy, take out of the box, and immediately load up with coins at a bitcoin ATM and then 'tap and pay' at a bitcoin-enabled NFC point-of-sales terminal.” Paypal President David Marcus recently pronounced bitcoin a leader in revolutionizing commerce, but dismissed NFC as “technology for the sake of technology.” While rife with imaginative appeal, NFC hasn't made a significant dent in the market, while bitcoin remains in vogue.However, by combining with bitcoin, Sigsafe is exploring a new route for the protocol.First off, the device can be used as a hot or cold wallet system by locking in a single address the tag is allowed to sign transactions to and from.It also can function as a debit card when paired with NFC-enabled devices.

Once compatible POS terminals crop up – software updates for this compatibility are also forthcoming – the tag would provide the functionality of a debit card.If HTML5 browsers incorporate NFC, users could even carry out e-payments with the touch of the key tag.Key tag owners can lay down a variety of transaction rules.Among them, users can require a password, establish a maximum transaction amount, or feed it any number of whitelisted spending addresses.An ECDSA signature takes approximately 0.2 to 0.6 seconds to sign.The tag wakes up when the presence of a NFC-supported device enters its field.A green LED flashes if the transaction is authorized, if not, it transmits an error to the host and flashes red.Over the course of the device's life, it could sign approximately 80,000 transactions.The tag can function without a battery, but it includes a battery and clock to enable time-dependent transactions.It could potentially support advanced features like multi-signature wallets and hierarchical deterministic wallets.
