The Security of Debit Transaction Limits
Transaction Limits for Interac Flash and Interac Debit on Mobile
Interac Flash® and Interac® Debit on Mobile are faster and more convenient than traditional chip and PIN transactions for everyday purchases. They’re also just as secure, thanks in part to transaction limits:
- A single card-based contactless transaction cannot exceed $100
- Cumulative spend limits set by banks and credit unions
When the cumulative spend limit is reached, you are prompted to insert your card and enter your PIN to complete the transaction. This validates you as the legitimate cardholder and resets the limits.
