Signature Debit can take place at a retail location or an online Web site.
Transactions are routed through the credit card networks (e.g., Visa® and MasterCard®) but are paid using a consumer’s funds on deposit in their checking or savings account.
No entry of a PIN is required for a signature debit transaction.
As a result, there may be a heightened risk of fraud, and typically a higher interchange rate is charged to the merchant.
