Automatic transaction on credit card to stay active
I agree with the rest of the answers -- you're probably better off just using it for some predictable flat-rate recurring monthly service like NetFlix, or making a charitable donation if you're into that sort of thing. But since that wasn't what you asked, I'll try to provide an answer: If you don't mind throwing away money, send money to yourself using PayPal. Here's how:  Set up a PayPal Business Account, and use your personal PayPal account to send funds to it by setting up a PayPal subscription. PayPal says "You can have one Consumer account and one Business account." A PayPal Payments Standard business account has no monthly fee -- only transaction fees. According to PayPal, "in order to set up a repeating payment, [you] would need to create a Subscription or Recurring Payments button from the Merchant Services tab" (in the Business Account). You would then click the link/button to set up the subscription from your personal PayPal account, to make it send money to your Business account on an automatic schedule. You can then, at your own leisure, send the money back to your personal account without paying a second transaction fee, then finally send it back to your bank account. Or, if your bank account is not yet tied to your personal account, you can tie it to the business account instead, and deposit the funds into your bank account. Unfortunately, this step can't be automated. Again, to reiterate, you're much better off just using it for something recurring.
