Smart Rules

When perpetrators gain access to cards and OTP or UPI details, they attempt to execute numerous transactions rapidly. Smart Rules offers a solution by allowing you to set restrictions on email address, mobile number, card details, and UPI within a defined time frame, thereby mitigating sudden increases in fraudulent activities. You can create a smart rule to block any transactions that exceed the set:

• Transaction limit
• Amount limit
