Is it safe to share my credit card number for a free trial that says there is no charge today?
Proceed with caution. Many free trials that require a card automatically charge you after a short period, and some sites use the card details for unauthorised charges immediately.

Explanation
Free trial card entry fraud works in two ways. In the first, you are enrolled in a subscription that is deliberately hard to cancel before the trial ends, resulting in a large recurring charge. In the second, the site collects your card details for immediate or delayed fraudulent use. Even when the trial is genuinely free for the first period, the business model relies on you forgetting to cancel. Before entering card details for any free trial, check whether the refund and cancellation policy is clear and easy to exercise, whether the site is a known legitimate business, and whether you can set a calendar reminder to cancel before the charge date. Consider using a virtual one-time card number from your bank for free trials if that service is available to you.
A useful distinction: reputable companies use free trials to demonstrate a product they believe you will keep; subscription-trap operators use them to obtain billing authority they intend to exploit. You can usually tell which you are dealing with by how easy the exit is. A clear cancellation button, an advance reminder before the first charge, and a plainly stated renewal price all signal the first kind. A cancellation path that requires phoning a helpline with limited hours, terms that hide the renewal amount, or a trial that converts to an annual charge rather than monthly all signal the second — and are worth treating as disqualifying before you type a single card digit.

What to do now
- Read the cancellation terms before entering card details
- Set a calendar reminder to cancel before the trial period ends
- Consider using a virtual card number if your bank offers one

Frequently asked questions
Can I get a refund if I forgot to cancel a free trial?
Some companies refund promptly on request. If they refuse, escalate to your card issuer for a chargeback on the grounds that you did not consent to the ongoing subscription.
What is a virtual card and how does it help with trials?
Many banks can issue a temporary card number with its own limit that you can freeze or delete after signing up. If the company tries to charge later, the payment simply fails — no dispute needed.
