It often takes a long time for a device's battery to completely crap itself out, usually it just loses its capacity, and since these wallets last a long time on a single charge, even losing 80% of the battery's capacity won't make using it too inconvenient.
Thanks. It seems that the battery of the Nano X lasts for a very long time. As long I'm able to use the device for a couple of years, nothing else matters. My Ledger Nano S is dying (screen very dim) so upgrading to the new version would be ideal. A great thing about hardware wallets (especially the ones offered by Ledger) is that they're durable, reliable, and extremely secure to use. They may be expensive than other solutions (paper wallets, bearer instruments like the OpenDime or Tangem Card, software wallets, etc.), but I'd say they're worth every penny.
I've been looking into other hardware wallets for Bitcoin, and I've found one called the "ColdCard" by Coinkite. It looks like a little calculator, yet it seems to do its job well for securing Bitcoin transactions on the go. What I like most about this device is that you can make offline transactions with it. It works on its own (standalone) without the need of a computer or mobile device. The only thing is the price, but if it works as intended, it's a great alternative to the Ledger, Trezor, or other hardware wallets on the market today.
So because of this thread I ordered some Tangem cards
..
Look nice. The RFID is a bit weak IMO. My phone reads a lot of other RFID cards easier then this.
With that being said I do not know if it's something in the app that they use doing something odd with the read that is causing it to ask to scan multiple times.
Other (non crypto) apps reading other cards just tap and it's there.
The app is nice, and I can see this as a nice way to pass someone a known amount of BTC (or ETH since I got one of those cards too) without worry.
Stay safe.

The cards looks great. I'd personally buy it as a souvenir or collectible, than using it seriously for crypto payments. The RFID chip may be weak, but at least the phone is able to recognize the card. What I like most about the Tangem Card is its variety of crypto offerings including (but not limited to) Bitcoin, Ethereum, XRP, and more. The OpenDime is only limited to Bitcoin and Litecoin, so the Tangem Card has an advantage here.
I wonder if the Tangem Card's level of security has been put up to the test? I've seen that it's possible to steal information from RFID chips using a RFID scanner. Just like anyone with an RFID scanner is able to steal your credit card information (if it has an RFID chip), the same could be done with the Tangem Card. Unless the card itself has some level of encryption, I don't see it as a viable solution for storing crypto in the long term. It's always recommended to store small amounts of crypto on bearer instruments like the OpenDime or Tangem Card just to be safe. For serious crypto use, hardware wallets are unmatched for now.
