# Can I use Halocard to sign-up for free-trials?

Yes, Halocard can be used to sign up for free trials on many websites.

When creating a card for a free trial, you can [set a spending limit](https://ask.halocard.co/en/article/how-do-i-set-spending-limits-for-individual-cards-bwd47x/) that matches the expected cost of the service. This helps ensure the card cannot be charged beyond what you expect once the trial ends.

Some merchants apply additional checks for free trials, such as charging a small authorization amount to confirm the card is valid. Make sure your card has sufficient balance for any temporary authorization, enter the billing address accurately at checkout, and avoid repeated retries if a sign-up is declined.

For added protection, Halocard may automatically **lock a virtual card after four consecutive declined transactions** to prevent misuse if a card is entered incorrectly or reaches its limit.

###### Free trials and acceptable use

While virtual cards are useful for managing trial subscriptions, creating multiple cards to abuse free-trial offers or attempting large-scale “trial farming” may result in account restrictions or suspension. Always use Halocard responsibly to avoid interruptions to your account.
