Hello everybody! Gzuuus here, how is everything going here?
As an enthusiastic hardware developer, BTC and LN lover I'm trying to develop some prototypes to build a functional PoS that uses LN and allows you to receive payments easily anywhere.
I closely follow great contributors to this ecosystem like Ben arc with his amazing projects (https://github.com/arcbtc), the incredibly useful guides of @DarthCoin (Hi Darth👋) and all those people who are creating and expanding this beautiful free and open source community.
Inspired by the recent and brand new Bolt card from the guys of coincorner, and Ben's great LN PoS FOSS project (https://github.com/arcbtc/LNPoS) I was wondering if there is any project that allows you to have NFC functionality on a LN PoS so we can develop our own NFC cards based on LNURL-withdraw and play around a bit.
The idea is that it is a piece of hardware independent of the mobile phone that follows the principles of the standards proposed and collected by David Coen in his github repo (https://github.com/theDavidCoen/LNURL-withdrawPOS) to create an ecosystem where we can all use our NFC cards and spend our satoshis freely.
I think Ben's project is a good starting point (https://github.com/arcbtc/LNPoS) since it is based on ESP32 as core and nowadays there are many modules to read/write NFC cards like the PN532 module (https://www.nxp.com/docs/en/nxp/data-sheets/PN532_C1.pdf), the question would be how to integrate it in the LNPoS to read the LNURL-withdraw of the NFC card and process the payment.
I look forward to your comments and responses, let's expand this and keep buidling ⚡⚡
