Stripe message

When using the Stripe method of paiement that I just added to my site one of my client got a donation failure message and I got this email from Stripe team. What's that and how is possible that your Stripe paiement method has such error?

Hello there, and welcome to Stripe!
We noticed that you are passing your cardholder's full credit card number to Stripe's API. We strongly discourage you from handling this information directly because doing so:
 Potentially exposes your customer's sensitive data to bad actors
 Excludes your payments from protection by Radar, Stripe's fraud protection solution
To keep your customer's information safe, we were unable to process the unsafe charge you just sent us. In order to process payments securely on Stripe, change your integration to collect payment information using tokenization. Tokenization ensures that no sensitive card data ever needs to touch your server.
In rare cases, you may have to continue handling full credit card information directly. If this applies to you, you can enable unsafe processing in your dashboard.
For any questions, just reply to this email and we'd be happy to help.
Yours,

The Stripe Team
