One-time use virtual cards are a powerful tool for businesses that need to make secure online payments without exposing their main account details. DogPay supports this use case by allowing you to generate virtual cards with a single-use limit. When a payment is processed, the card is automatically locked, preventing any further charges. This is particularly useful for paying contractors, purchasing digital services, or funding ad accounts where you want strict control over spending. To set up a one-time card, log into your DogPay dashboard, navigate to the Cards section, and select 'Create Virtual Card.' Choose the spending limit and set the card to expire after the first use. The card details are then shared with the vendor for a single transaction. After the payment settles, the card becomes inactive, adding an extra layer of security. DogPay's infrastructure includes real-time transaction monitoring and the ability to set spend limits per card, giving you fine-grained control over your payment operations.
