I don’t care for those solutions either as Apple Pay is brilliant. Use it on Watch and iPhone. The iPhone appears to be more failproof (Watch sometimes (+/- 5% fail rate) fails on terminals that demand “the card” on top of the screen”) but it’s very nice. And no limit due to the security! Those rings still demand a code over €25.
I understand people would want them though, so I support the idea for Bunq to atleast offer the ability to link a NFC-gadget.
