Have you ever run into difficulty with needing to authenticate with chip+PIN? Like while traveling?
That would be my big concern with this; it would make it very difficult to pass a PIN check, to say the least!
Super cool idea. I might just try it myself and see if I run into issues.
What I modified was in fact a contactless payment token. It had the form factor of a payment card, but it only does NFC.
I have another card for chip+pin.But I almost never use it where I live, because all limits were lifted on contactless payments a few years ago. If I try to pay something really expensive contactless, it will ask me for the pin - which is specific to the payment token.
Do you mind if I ask what bank issued those? Why? Does the chip+pin also tap or are they features on totally separate cards?
I've never heard of a separate tap to pay token (outside of perhaps transit passes or like, arcade cards), and never a card based tap transaction that asks for a pin.
Payment tokens are very common. Usually they're sold as keychains, wristbands or rings, and they're provisioned to work with the myriad of payment processors out there - which aren't banks.
in my case, it's a token from iCard. The way it works is, it's connected to a regular bank account number with an IBAN number (supplied by iCard when you activate the token), and you transfer money to it that you can then spend with the contactless token. The nice thing is, if you lose it, you can't lose anymore money than you put on it.
