# Encryption
Xplor Pay uses advanced encryption technologies to protect payment data during every stage of the transaction process. Encryption helps ensure that sensitive information is secure from the moment a transaction starts until it reaches its final destination.
## How Encryption Works
Encryption is the process of converting sensitive information into unreadable code. Only authorized parties with a decryption key can unlock the data. This makes encrypted data useless to hackers if intercepted.
### Step-by-Step Process
1. **Transaction Start:** The customer swipes, dips, keys, or taps their card on an encrypted device.
2. **Data Encryption:** The card data is instantly converted into an unreadable code before leaving the device.
3. **Secure Transmission:** The encrypted data is securely sent to Xplor Pay's PCI-compliant data center.
4. **Decryption:** Once the data reaches Xplor Pay, it is decrypted and sent to the bank for authorization.
## PCI-validated Point-to-Point Encryption
Xplor Pay's PCI-validated Point-to-Point Encryption (P2PE) solution offers an extra layer of protection for card data in transit. P2PE encrypts data immediately when a card is swiped, dipped, keyed, or tapped and keeps it encrypted until it reaches Xplor Pay's secure environment.
### Benefits of PCI-Validated P2PE
* **Reduced PCI Scope:** Encrypted payment devices help businesses reduce their PCI DSS scope, simplifying compliance efforts.
* **Simplified Compliance:** Merchants using encrypted devices no longer need to conduct vulnerability scans or penetration tests.
* **Faster PCI Self-Assessment:** Merchants can complete the simplified SAQ P2PE form, reducing their questionnaire from over 80 questions to just 32.
By combining encryption with other security measures like [Tokenization](/getting-started/security-solutions/tokenization.md), Xplor Pay helps businesses protect payment data, simplify compliance, and reduce security risks.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.xplorpay.com/getting-started/security-solutions/encryption.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
