The SatsMobiBot is able to show

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

for the payment. NFC is the technology 
which 
makes possible to pay just with a

Card Keys
You own your card keys. You can in any 
moment disconnect your card from the 
system and rewrite the card. 
The keys belong to the user. 
You can also immediately empty your 
card account to an onchain address you own. 
Here what you get:

the private wipe keys of the card. 
You can use these keys to wipe out your card 
and disconnect from our system whenever you want. 
Just bear that using the wipe keys provided by 
writing them to the card is an irreversible action 
and will definitely disconnect the Card from 
SatsMobi and the whole system.
withdraw all the funds back from the card to your 
on-chain address whenever you wish.
