How to use "burner" debit cards for trial memberships

Initiating trials for subscription-based services such as audio and video streaming, cloud gaming, and food deliveries usually requires inputting debit/credit card numbers. The trial services automatically default to recurring billing at the end of the trial period if the trial is not cancelled. If you'd like peace of mind should you forget to cancel a trial membership, burner cards are for you.

With Oxygen's banking service, you can use unlimited "disposable virtual cards" for which you may set spend limits. New debit card numbers, complete with CVC codes and expiration dates, are generated after each transaction. 

I set a $2.00 spend limit so my burner card would deny charges exceeding the $2.00 amount. This amount is also a sufficient balance for authorization charges which are debited from and refunded to your account at the initiation of the trial so the service provider can authenticate the card.

I prefer using the Oxygen app on my phone, which is available on iOS (iPhone/iPad) and Android platforms. 

To view my burner card, I navigate to "My cards" under the Overview tab. From there, I swipe over to the Disposable virtual card tab where I can reveal its details by tapping on the card. Right below is the option to set its spend limit. 

Having a burner card is also useful for making purchases if you want to protect yourself from fraudulent charges should any transaction details be compromised
