    Folks, don’t do this—you can derive card type from the number. Don’t make the person do the work. #ux +@WeTransferpic.twitter.com/wM6JNYdaUH

        @aral isn't it a precaution against scammers who just have the number but don't know the card type?

        @charlesarthur It’s always a trade-off between security and experience. Would be even more secure if we added a captcha & two-factor auth :)

        @aral @WeTransfer @MrAlanCooper I agree in no need to ask which card. So should we be asking "Credit Card or PayPal" in this situation?

        @aral Yes, it it easy to derive but it is a layer of extra protection against automated attacks. That is why it is done and recommended.

        @NickKirkman Quick, someone tell Stripe that—they’re about to go down ;) (In terms of security vs usability, imo latter wins in this case.)

        @aral I worked at a place who felt the same until a sustained attack lost $16k in 48 hrs. Banks told us it is common. We added this plus...

        @aral @hbons @WeTransfer Most users don't know you can derive card type from number and might be very insecure when filling out the form.

        @hbons Hide card type. As user types card number, show card (ooh). Also avoids: user selecting wrong card in step 1+@_nilswerner @WeTransfer

        @aral @hbons now this I disagree with. Show them greyed out and staurate the matchin ones, yes. But too much hidden magic I wouldnt like.:-)
