I just setup my new Tapsigner with nostr:nprofile1qqsvxq03xdev3uxehjqcdkr5lfzl5vawmcf7vm6ps73m6ghwg8y4k2spz4mhxue69uhk2er9dchxummnw3ezumrpdejqz9nhwden5te0dehhxarj9eekcmm5dpujuamfdcq3yamnwvaz7tmsw4e8qmr9wpskwtn9wvuasnac, and the process couldn't have been easier. In under a minute I was able to create a new Tapsigner key, back it up, and assign it to a new wallet. That wallet now uses the Tapsigner as a single-signing key, requiring an NFC tap to send any coins.

The Tapsigner also works with multi-sig wallets, and can be combined with other hardware wallets/signers and software keys to authenticate a multi-sig send transaction. And it's only $20!
