Bank Policy on Reversing Fraudulent Debit Card Charges

Banks must investigate unauthorized charges within 10 days and reverse if fraud is confirmed. 2026 updates align with Visa/Mastercard: Zero liability applies if you notify within 60 days (2 days ideal for fraud). Banks aren't liable post-investigation if you authorized it.

Mini Case Study: Jane reported a $500 fraudulent charge on day 1. Bank issued provisional credit Day 10, reversed fully Day 35 after police report confirmed scam.

Visa vs. Mastercard: Both mandate zero liability, but Visa offers faster provisional credits (5-10 days).
