@marcoscaceres, in cases where the merchant makes use of 3-D Secure authentication, phone is a data point that figures into that protocol. As one person commented: "The more information provided, the better. This is due to fraud analysis being doing prior to charging the card on the PSP's side. This means that the merchant can have a transaction declined, not by the bank, but rather by the PSP itself." Can your concern be addressed through UX? The payment handler can indicate that phone number is optional. If the user provides one, it is returned. Ian My goal was to provide rationale for its usage, which I believe I have done. However, I hear that you remain concerned. I am not sure -- You are receiving this because you are subscribed to this thread.
