TANGEM 2.0 is far from perfect or acceptable, but it's not that bad.
True.
While having Passport 2, I (with that) use Tangem for on-the-go transactions during my business trips relying on its It's unique recovery mechanism which allows me to not worry about my SEED, PIN codes etc.
I have three cards bundled in one set (A1, A2,A3). Any card from the two in this set serves as a backup for the remaining third. Cards from the same set can be assigned the different access codes. For simplicity, the same PIN is set up for all cards. Suppose I completely forgot this PIN. I take any card (for example A1) and when asked for a PIN, answer that I don’t remember. I asked to enter a new PIN and, after entering it, bring any of the two remaining cards to the mobile. Let's use A2 for example. After this, they ask me to bring A1 again and the new PIN (entered before) is recorded on it. I repeat the same procedure with card A2 (restored using A3 or A1) and card A3 (restored using A2 or A1).
As simple as that.
Nice additions from igor72:
"This wallet has the following disadvantages:
1. If you use entropy generated by a wallet, you have to trust the manufacturer.
2. When using your seed, you have to enter it into your online phone, which means potentially compromising the seed. The solution is to use an offline phone to enter the seed with a full reset after the procedure. Inconvenient, but basically acceptable.
3. Since this card does not have a display, it is not possible to reliably verify the authenticity of addresses and amounts;
https://bitcointalksearch.org/topic/m.638836771. This is applicable to any hardware wallet. You need to trust even the dice rolling or coin flipping if using them to generate SEED.
2. See the nice Yamane_Keto answer to that.
3. Almost impossible (for malware, if any) to substitute those data unless you have rooted jailbroken mobile.
Why to bring the other persons' biased thoughts here? Do you have you own ones?
