So I'm assuming you mean you want to be able to move bitcoin (not going to respond to monero) a cross borders in an emergency

If you want to carry a physical wallet across borders that's probably a higher risk than just having a multisig setup with keys distributed to both locations. Though physically securing it in your second location when you aren't there has its own risks.

I'm not sure which wallets you're looking at that are getting obsoleted but since even the earliest wallet types still work on the bitcoin network maybe you're buying it from closed source companies that you aren't actually managing the hardware for?

If you really don't want to rely on a finalized product seed signer is open source and uses commodity hardware but I think best practice is to not store your seed phrase on it since its not designed to have a secure element and general computing hardware might be a larger attack surface for key extraction. I'm sure there is a case to be made the other way.

The other option is a brain wallet

Exactly, I was refering to Ledger.

What’s a brain walllet? One that you memorize the seed phrase?

I understand the argument of passing the hardware wallet through security checkpoint.

Would Tangem then be a good alternative?

Brain wallet just means memorize the phrase but its more a last choice emergency situation where you have to get out and can get to safety fast enough that you won't forget your phrase

As for tangem I have only seen it in passing before.

I can't figure out if the firmware is open or not. Its interesting for your use case cause Ican see how you might be able to hide it as a credit card.

I would be worried about it not having a screen to verify addresses when you sign.
