How do you verify there is enough balance in the account, etc? Pin+chip just verifies that the card is yours, not that the card can actually pay for anything.

How do you verify there is enough balance in the account, etc?
Pin+chip just verifies that the card is yours, not that the card can actually pay for anything.
For example, you could use a VISA gift card with $0 balance to pay for things if you had a system that was accepting transactions while offline.
- Reason077 6y agoThere's no way to verify the balance offline. But, generally speaking, the offline mode is only used if there's a network/connectivity failure, and there's generally no way for a fraudster to know in advance if that's going to happen. The acquirer (ie: the merchant's bank) accepts liability in the case of fraudulent transactions. There are limits on offline transaction values, and merchants that have high fraud risk may not allow it at all.
