DeviceID and Token Key mapping in VTS

Hello Experts,

 

In my mobile wallet, If I use same credit card in two different mobile devices, Would there be only one visa token key generated for a PAN(16 digit credit card number) or different PAN for the same PAN for both mobile devices.

 

I heard the Visa token is generated and stored at Visa Token Vault. If so, would the token generated is linked to device, card number etc.

Appreciate your inputs.

Thank You

Paul

Hey @paul_earnest,

 

I'm updating my answer to this post, I have also confirmed that the same wallet, on multiple devices will produce unique tokens, not the same token.

Hello @DianaTran-Yee,

If there are multiple mobile applications like Apple Pay, Mobile Wallet Pay etc in the same device uses the same PAN, then would it be still one token per device or one token per mobile app per device? Please help me out to get confirmation. Thank You, Paul

Hey @paul_earnest,

 

To answer your question, across different digital wallets the tokens will be different for the same card number.

For instance Fitbit and GooglePay on the same device will have two unique tokens for the same PAN if the PAN is enrolled in both services.

I have also confirmed that the same wallet, on multiple devices will produce unique tokens, not the same token.
