[VB.NET] Public Sub BalanceInquiry()
[C#] public void BalanceInquiry();
This method sends a balance inquiry request to the Vital/TSYS transaction processor. The CardTrack2Data property must be populated with the data from the magnetic stripe on the back of the card, and both DebitPIN and DebitKSN must contain data from a certified PIN pad device. If the authorization request was successful, the Code property will contain "00", and the Balance property will contain the card's current available balance.
