The SatsMobiBot is able to show you spendable balances and transactions. You can top up your card from there. The amount that you have there is the amount you can spend with the card. For security reasons your card has fixed spending limits, which are by default:
- 500k Sats in a single transaction
- 1M Sats daily
The card can be accepted everywhere Lightning payments are accepted and a NFC device is used for the payment. NFC is the technology which makes possible to pay just with a touch of your ring. Being Lightning a early technology, the transaction may fail, depending on the shop where you are using it.
You own your ring keys. You can in any moment disconnect your Ring from the system and rewrite the card. The keys belong to the user. You can also immediately empty your Ring account to an on-chain address you own. Just be sure to be also a user of BitcoinVoucherBot (just opening first time and hitting /start is enough). From that bot, then hit the command /getcard. Here what you get:
- the private wipe keys of the Ring. You can use these keys to wipe out your Ring and disconnect from our system whenever you want. Just bear that using the wipe keys provided by writing them to the Ring is an irreversible action and will definitely disconnect the Ring from SatsMobi and the whole system.
- withdraw all the funds back from the card to your on-chain address whenever you wish.
Open source Software and Open Standards involved
All the Card/Ring system is based on opensource software and standards. Please see below the details:
- NXP NTAG 424 DNA
The Ring is delivered as fastest possible. It’s your responsibility to provide your correct address as we cannot check it. We will send to the address provided without any additional check.
If you dont want to manage your Ring through out SatsMobi system, and you want to get the Ring totally blank just notify on the order notes. Please bear in mind that in this case, the Ring will be useless if you are not able to program it and connect to your node.
