# Get started with Satochip
This setup is working out of the box on:
- [TailsOS](https://tails.net/) (can remain offline, but to see new transactions and balances needs an internet connection.)
- Debian 12
- Windows 10
What you need to access the wallet stored on the card:
* the smartcard loaded with the Satochip java applet and initialized (this was likely done by the one handing the card to you)
+ a smartcard reader (here a ACS ACR39U-N1 PocketMate II USB)
* a computer with a USB port capable to run:
- [TailsOS](https://tails.net/) (can remain offline, but to see new transactions and balances needs an internet connection.)
- Debian 12
- Windows 10
- other operating systems will likely work, just not tested
