@johannes#102511 Just because in the EU we are used to fancy printed numbers and signature fields doesn't mean it is normal in other countries
Please name just three banks anywhere in the world (besides bunq and Goldman) that have neither "printed numbers" (on the front) nor signature fields on their cards. 😉
They are features that clerks have been taught and trained for many, many years to spot as security features. See this example from a European acquirer, just three years old, from 2016. I maintain that that's what's considered a "normal" Mastercard throughout the world - and still is "normal" today.
Quite some credit card companies worldwide still require credit cards to be embossed, I quoted numerous reports just a couple of days ago somewhere on Together.
I do agree however that Apple's Cards as well as consumer payment devices / smartphones have greatly paved the way for acceptance of "non-traditional" payment devices and will continue to do so. Will probably be a non-issue in a couple of years.
Still, for today, bunq's physical card designs on the Travel Card - are not optimised for maximum acceptance at merchants. Maybe even less so on the Travel Card (with the sole exception of the word of credit). Had they done so, optimised them for maximum acceptance, the cards would feature a horizontal design with embossed letters and signature field. So they're still a bit ahead of the curve in their designs, in my opinion - which, just to be clear, certainly isn't "wrong" in my book 🙂 (it's just something to be aware of)
