One of the self-proclaimed goals of VCR was to cut down the number of days it took to resolve a payment dispute. To attain this goal, VCR reduced the timeframe for the initial response to a dispute from 45 days to 30 days. Now, instead of taking up to 150 days to resolve a payment dispute it takes up to 70 days for Allocation cases and up to 100 days for Collaboration cases. Visa also no longer allows merchants to default to no response in reaction to a chargeback. Merchants must accept or contest liability, or they face penalty fees for lack of response. Visa used VCR as an opportunity to reduce the volume of chargebacks as well. VCR requires issuers to proactively review associated transactions (credits, reversals, adjustments) before filing a payment dispute. These transactions are identified looking at historical transactions with similar characteristics using Visa’s authorization, clearing and settlement systems. Should an associated transaction render the payment dispute invalid the chargeback is rejected before it is filed and no chargeback defense is needed, saving both the issuer and acquirer a lot of admin work. Visa also phased out the previously popular “unrecognized” reason code (number 75), forcing issuers to help cardholders identify the transactions they are contesting and categorizing them with greater detail.
