Change card PIN using Curve app

Yeah, that’s how it could be implemented. But as of now, I don’t see such an option in the Curve app, or am I missing that? I can only view the existing PIN, not change it in the app.

I thought PIN verification was done on the card card offline?

Hence why if you change the PIN remotely, it requires a successful transaction to write the new PIN to the card, but if you change the PIN at an ATM it’s instantly updated irrespective of being online or not?

I think this isn’t quite true.

PIN verification happens offline for all card transactions, but I believe it is always online for ATM withdrawals, even for offline cards? I believe I read something about this once on the Monzo Community. Apparently it is to do with “Scripting” which writes new data to the card when presented in an online transaction. Perhaps somebody can confirm this.

If so, it would be possible for Curve to allow you to change the PIN in-app, with advice to force update the new PIN on the card chip by simply going to an ATM and conducting a withdrawal. The ATM would go online to verify the PIN, and Curve would reply with the “new PIN” you had just set. Scripting would then run on the Chip, as usual, therefore writing the new PIN to the Chip.

The good thing about this is that it would allow customers in other countries, where the Change PIN option doesn’t appear on ATMs to update their PINs without having to do anything special at the ATM - any ATM would do.

Ahh, that sounds very interesting indeed!

I know what I’ll be spending my evening researching now :joy:

Do report back with how you get on!

If you are looking up scripting on the Monzo Community, I think it was a post by Rika (who works at Monzo) which explained it?

Something discussing what the difference was between online and offline transaction processing anyway.

@andyk I have found something which seems to corrobate what I was saying, but I think it wasn’t exactly the post I was remembering (there must be more out there)!

This is from way back, when Monzo was still known as Mondo.

Apologies for the triple post, but this is the thread I was originally thinking of (I think!).

Interesting what was said in the last post I quoted, though, in that a specific set of menu options had to be used to trigger scripting. Perhaps that means you have to go to PIN options and select “Unlock PIN”? Although I would have thought a withdrawal would do it most of the time.

The need to change PIN on a certified? MASTERCARD ATM (what the hell is that??) is totally NONSENSE.

I tried 10 Portuguese ATM (2 of them where really ATMs - NOT only MULTIBANCO - the portuguese ATMs, that support VISA; MASTERCARD, MAESTO, by the way…) and NONE of them showed me the option to CHANGE the CARD PIN!

Even worst is the totally false information on CURVE HELP pages, and i quote: My PIN – Curve

When you first download and set up Curve, you’ll be asked to create your card’s PIN.

FALSE! The only PIN that the user can define is the APPs access PIN!

So… Curve… do we have to live with the PIN MASTERCED chose for us???

Portuguese ATMs don’t allow PIN change for non Multibanco (Portuguese payments scheme) cards, so effectively there’s no way for me to change the card PIN.

It would be great if the PIN could be changed in app.

Yes. please give us this function to change the PIN in the APP

I GAVE UP trying to change the PIN. It’s impossible in Portugal.

So, i remembered another PIN, just for CURVE.

My problem is, if the PIN is compromised… will i have to PAY for a NEW card just to get a NEW PIN???

This is nonsense! By 2021 there must be another way to change the PIN!

Even if you get a new card, your pin remains the same.

Thank you very much for the information. I have changed my Curve card PIN at a Euronet ATM in Madrid, Spain.

EURONET ATM are avalaible in Lisbon. I changed my curve card pin there. Boa tardé.

Sounds to me like the Portuguese ATMs need to find a way of better supporting products that aren’t their own! Changing a PIN Number has always been done at an ATM :thinking:

Good news for French users.
You can change card PIN in a ATM located in Paris

ATM (Euronet)

Location : [Centre Commercial Beaugrenelle]

(Centre Commercial Beaugrenelle - Google Search)

12 Rue Linois, 75015 Paris
ATM located on level -1

Worked for me ( December 2021)
I get the same Pin for my curve card, my crypto. com card, and my main bank card.

Nice to know, but this is still nonsense!

Users shouldn’t be forced to find an ATM located in the “end of the world” to change the PIN!

Com’on CURVE! You could implement this option through the app if you really wanted!

Not to mention that you can’t choose it at first either… :neutral_face:
