Bitcoin and NFC
Bitcoin we already know it, we know what it does, its characteristics and what is its purpose, but NFC, what is it and how can we link it to Bitcoin?
What is NFC?
NFC (Near Field Communication) is a short-range wireless technology that allows the exchange of data between devices. It emerged in the early 2000s and is based on RFID (Radio Frequency Identification) technology.
It has had a variety of uses since its inception, from contactless payment with credit cards and cell phones, to data transfer between devices, access to events or locations, fast pairing of Bluetooth devices, and object identification.
It is also used in public transportation cards and in the Internet of Things (IoT) industry, where it enables interaction between smart devices.
How can we combine it with Bitcoin?
The combination of Bitcoin and NFC offers a number of interesting possibilities, such as:
Contactless payments: users can use their smartphones or other NFC devices to make payments in stores and other establishments.
Funds transfers: Users can transfer funds between each other using their NFC-enabled devices. Many Bitcoin wallets already allow this option.
Data storage: Although not very secure as they can be read with any NFC device, if we have an NFC card or chip we can "record" inside it our recovery words, a Bitcoin address to receive payments or simply any other information we wish. Remember to keep it well guarded to avoid information leaks.
Bolt Card NFC Lightning Network
The Bolt Card is a physical card that can be used to pay with Bitcoin through the Lightning Network.
Physical NFC cards such as the Bolt Card mark a new step in the adoption and use of Bitcoin as a payment and exchange instrument, breaking down barriers of limited usability and speed that were one of the negative aspects that worked against the use of Bitcoin as a means of payment.
Thanks to the second layer, known as Lightning Network, Bitcoin has a mechanism that helps it not only to increase its speed to levels even higher than traditional payment instruments, but also opens the door to a universe of innovations that allow the end user to easily use it as a payment instrument without complications.
To use the Bolt Card, the merchant, or your counterpart, only needs to generate the corresponding charge from their phone or NFC device and we bring the Bolt Card close to them so that the charge is debited from it.
Key features include:
⚡ Lightning payments.
⚡ NFC / Contactless
⚡ Send payments in BTC, at the exchange rate of any Fiat currency.
Challenges
There are some challenges associated with the combination of Bitcoin and NFC. For example, the security of NFC devices is a major concern, as they could be hacked to steal funds or personal information.
In addition, the widespread adoption of Bitcoin and NFC is still in its early stages, so it can be difficult to find places to use these technologies.
Despite these challenges, Bitcoin and NFC have the potential to revolutionize the way we make payments, transfer funds and authenticate ourselves. As these technologies develop and become more widely adopted, we are likely to see an even wider range of applications for them.
I hope I've been helpful to everyone!
Let me know if you know of more uses for NFC and what context you've used it in. Let me know in the comments. I read them...

Bitcoin y NFC
Bitcoin ya lo conocemos, sabemos qué hace, sus características y cuál es su objetivo, pero el NFC, que es y cómo podemos ligarlo a Bitcoin?
¿Qué es NFC?
NFC (Comunicación de Campo Cercano o Near Field Communication en inglés), es una tecnología inalámbrica de corto alcance que permite el intercambio de datos entre dispositivos. Surgió a principios de la década de 2000 y se basa en la tecnología RFID (Identificación por Radiofrecuencia).
Ha tenido diversos usos desde su creación, desde el pago sin contacto con tarjetas de crédito y teléfonos móviles, hasta la transferencia de datos entre dispositivos, el acceso a eventos o lugares, el emparejamiento rápido de dispositivos Bluetooth, y la identificación de objetos.
También se utiliza en tarjetas de transporte público y en la industria del Internet de las cosas (IoT), donde permite la interacción entre dispositivos inteligentes.
¿Cómo podemos combinarlo con Bitcoin?
La combinación de Bitcoin y NFC ofrece una serie de posibilidades interesantes, como:
Pagos sin contacto: Los usuarios pueden utilizar sus teléfonos inteligentes u otros dispositivos NFC para realizar pagos en tiendas y otros establecimientos.
Transferencias de fondos: Los usuarios pueden transferir fondos entre sí utilizando sus dispositivos con NFC. Muchas carteras de Bitcoin ya permiten esta opción.
Guardar datos: Aunque no muy seguro pues pueden leerse con cualquier dispositivo NFC, si tenemos una tarjeta o chip NFC podemos “grabar” en su interior nuestras palabras de recuperación, una dirección Bitcoin para recibir pagos o simplemente cualquier otra información que deseemos. Recordar que hay que tenerlo bien guardado para evitar fugas de información.
Bolt Card NFC Lightning Network
La Bolt Card es una tarjeta física que se puede usar para pagar con Bitcoin a través de la red Lightning Network.
Las tarjetas físicas NFC como la Bolt Card marcan un nuevo paso en la adopción y uso de Bitcoin como instrumento de pago e intercambio, rompiendo barreras de limitada usabilidad y velocidad que significaban uno de los aspectos negativos y que jugaban en contra de la utilización de Bitcoin como medio de pago.
Gracias a la segunda capa, conocida como Lightning Network, Bitcoin cuenta con un mecanismo que le ayuda no solo incrementar su velocidad a niveles incluso superiores a instrumentos de pago tradicionales, sino que también abre la puerta a un universo de innovaciones que le permiten al usuario final tener la facilidad de usarlo como instrumento de pago sin complicaciones.
Para usar la Bolt Card solo basta que el comercio, o tu contraparte, genere el cobro correspondiente desde su teléfono o dispositivo NFC y nosotros acerquemos la tarjeta Bolt para que se debite ese cobro de ella.
Entre las principales características destacan:
⚡ Pagos mediante Lightning
⚡ NFC / Contactless
⚡ Enviar pagos en BTC, al tipo de cambio de cualquier moneda Fiat
Desafíos
Existen algunos desafíos asociados con la combinación de Bitcoin y NFC. Por ejemplo, la seguridad de los dispositivos NFC es una preocupación importante, ya que podrían ser hackeados para robar fondos o información personal.
Además, la adopción generalizada de Bitcoin y NFC aún está en sus primeras etapas, por lo que puede ser difícil encontrar lugares donde utilizar estas tecnologías.
A pesar de estos desafíos, Bitcoin y NFC tienen el potencial de revolucionar la forma en que realizamos pagos, transferimos fondos y nos autenticamos. A medida que estas tecnologías se desarrollen y se adopten más ampliamente, es probable que veamos una gama aún más amplia de aplicaciones para ellas.
¡Espero haya servido de ayuda a todos!
Dime si conoces más usos del NFC y que contexto lo has usado. Déjame saber en los comentarios. Los leo…

"Contactless payments: users can use their smartphones or other NFC devices to make payments in stores"
That's very important, to speed-up payment process with LN (scanning QR codes is like a bit of mess, truly speaking...)
reply
Thank you for your response. You are right, sometimes paying with QR is more cumbersome and slower.

Yeah we need to hack a system so we can just bitcoin nfc at credit card pos stations.. isn’t there one already?

Thank you for your response. I assume there is a system set up to allow such payments, whether it is not used by everyone is another matter.

I'm still a little freaked out it about Bluetooth and NFC radios (or whatever) and anything more than walk around money, which is how I use Lightning Network anyhow.
Am I a Troglodyte?

Hello, thank you for replying! You are not a troglodyte at all, but rather a cautious person I would say. You should always be careful with technology but with proper self-care rules there should be no problem using it.
reply
All LN wallets must support transactions via NFC, and NFC module must be active only when phone of payer is unlocked and the pop-up confirmation window is accepted by payer. Then such process will be faster than current scanning QR codes and still quite secure.
reply
Thank you for your response. Yes, exactly, the technology has its keys to be secure. There is no need to be afraid.

It's also not any easier than an NFC credit card, which itself has security benefits, chargebacks, etc. For that reason, NFC Bitcoin is actually better for the RETAILER than the consumer, which is ironic because it will be mostly pushed on the user side, by orange pillers.
reply
You're right about that too.

We are somehow still waiting on consensus and implementation of standards like Bolt12 and lnurl.
Some of the biggest exchange wallets, like Cash App, seem disincentivized to let users spend their Bitcoin, instead keeping it on their platform. They don't allow sending to lightning addresses, for example, only invoices, even though "regular" custodial solutions like Alby have done it for a long time (and it's stupid simple to implement).
The point is, it's going to be the little guys leading the way, which means only us nerds will use it.
reply
Thank you very much for your response. As for what you say is true, sometimes the technology is not understandable by all, and less by the large entities that lead the industry. But as you say it is us, the little nerds who try before anyone else the technology and somehow we make it accessible to others who do not understand it. Something is a start, and I believe that Bitcoin (despite what they say with ETFs), is now in all the news and world propaganda, something unthinkable a year ago. something good will come out of all this, its use is undeniable and people are already using it more than before. Time to time.

I love the idea of Bitcoin / NFC and the lightning network together. For the cold storage savings, I prefer to be disconnected from the internet entirely or as much as possible, but if I’m buying a burger or something like that for 10 bucks, anything that makes the transaction smoother, I’m all for.
If you’re storing your life savings on the lightning network for because on chain is just too much, then do what you can to mitigate having something like NFC on and get your funds on chain when possible, but that’s another can of worms!
reply
Thank you for your response. Yes, the Bitcoin issue and the security of our funds is something to always keep in mind. Always try to follow good security and privacy practices, and above all never trust, always verify.
reply
Good job explaining NFC
reply
Thank you very much for your support, I hope you learned as I did by creating this post. Greetings.
reply
I think both technologies could coexist perfectly, plus contactless payment with Bitcoin in any merchant would be fantastic, I guess at some point we will see this happen.
reply
Thank you for your response. I also think the same. Hopefully it will become normal in the not so distant future.
reply
Sounds like very complementary technologies to me
reply
Thank you for your response. You are right, one technology complements the other.
