Partial Payment

When a customer presents a Visa card and the available balance is less than the purchase total, the card issuer may return a unique response code along with a partial amount approved. Currently on the POS, Linga lacks a clear notification for the merchant.

We would like to see a prompt or notification on the POS screen when a partial authorization is received. The notification should:

Clearly alert the merchant that only a partial amount was approved.

Display the approved amount and remaining balance.

Offer the merchant the option to either accept the partial payment and request an additional form of payment (split-tender), or decline the transaction altogether, based on the return code.
