This would be a good candidate for leaving a country, right? You could carry it as if it was a bank card. The OPENDIME may bring up more questions, especially at an airport if it was in your bag?

[@glenncharles6622]

Great video. Thanks!

[@bushell53]

What happens if when setting up the 2nd address the CVC is entered incorrectly? Would it allow the address setup and expect the incorrectly entered CVC for the 2nd sweep? Hopefully not because if it does you could only trust slot 1 when being gifted the card.

Hey Ben. Loving your channel. What podcasting platform do you use?? Clearwell

[@BTCSessions]

Hey Devon! So for live stuff I use Streamyard, and for tutorials I use OBS and edit in iMovie. For audio podcasts I just upload via Anchor, and have also registered my podcast to show up on podcastindex.org

[@devonclearwell3748]

@@BTCSessions Hey Ben. I somehow managed to double message you. You replied to both, so thanks very much for that. Excellent info. And excellent show. Keep up the good work. Dev

[@jasongoerlich1538]

Can you deposit to the first address multiple times before sweeping? I am thinking about possibly using this for allowance with the kids. I really wish it was possible to tap it to the BlockClock Micro to get a balance on this.

[@21Million]

yes you can 6:34

[@kstenergy5804]

Another awesome video Cool fact: when verifying whether a Bitcoin address matches another, you can simply check the last 4 bytes of the address (last 4 digits on a bech32 address). The last four bytes are a checksum of the whole address. That is mostly important when pasting an address in a wallet for a transaction, but most wallets out there will verify whether the input address is a valid one already.

[@BTCSessions]

Awesome I actually didn't know this!

[@wallywattz]

Can you reuse the card for gifting as the initial gifter without having possession of the card? Would like to use to gift Sats to family and just send more every birthday or something.

[@ikust007]

Splendide et merci !

[@dipunm]

Did you cover the CVC code or does it have some camera protection? Is it the orange bit? I can't see where you are reading it from.

[@BTCSessions]

Ha I guess the writing was a bit faint with the image. It's clear to read in person though! It's in the box on the right of the card though!

[@jybevox]

QUESTION: Do we need to use the Nunchuk wallet to "sweep" the Satscard? Or is there other ways to "sweep" the bitcoin from the card? Thank you a lot for your videos. I got a Bitcoin node for a week thanks to you :)

[@BTCSessions]

Nunchuk is the first wallet to offer support for Satscard and some other NFC options, but I imagine we'll see others soon. Blue Wallet typically jumps on these things early so I would keep an eye on them as an alternative. Stoked to hear you're running a node - congrats!

[@gapost94]

Can this card be demagnetized? And what happens in that case?

[@osdias]

I don't understand why the 10x use limit on the card! Is it just so they can sell more of them? Can someone explain?

[@GroovyMisfit]

Why is an unsealed slot considered unsafe?

[@InappropriateShorts]

what would happen if you skipped to 4:41?

[@habibaghasafari2237]

I cannot see any scenario that justifies the use of this product. It is not trustless. You have to trust the manufacturer and also trust that the device is not a fake knockoff with malicious code which means means the reciever have to trust that you haven't given them a fake malicious device. Which means upon receiving the device, the reciever should immediately sweep the funds. So if that's the case, why not just do a lighting or on-chain transaction? It will be way cheaper and safer to just do a transaction.

[@BTCSessions]

I get your point, but isn't the same true of trust in a hardware wallet? Unless you build something like a seedsigner from independently sourced parts. The tapsigner's code is open source and you can use a command line tool to audit what's happening if need be. You can indeed just send a transaction. That said, I find this a good option for gifting Bitcoin to someone.

[@xiaodaigu5659]

I think your limiting your thoughts to large transactions. For small transactions of $25 - $100 USD, between someone that knows a little about bitcoin to someone that knows nothing about bitcoin, I think this is perfect, due to the low cost of the device and the ease of use. I can also see cases where these cards are pre-loaded with bitcoin in set amounts by a trusted party, and rarely swept, but just used in the same way notes are used. Not every financial transaction has to be 100% trustless to have utility.

[@xiaodaigu5659]

Also, one extra point. The card has X509 certificate, so you can verify it's genuine offline. It's the same way you know a hardware wallet is genuine, or the website you connecting to with your browser is genuine.

Ben! Where is your hair accent!?
