Secure Payment

Secure Payment

Last updated: 1 June 2026

At Quantum BT, we want every customer to feel confident when placing an order online. This page explains how payments are processed, how payment security is handled and what happens after a payment is completed.

1. Seller information

Quantum BT, UAB
Company code: 307526739
VAT number: LT100019735710
Registered address: Girulių g. 5, LT-12124 Vilnius, Lithuania
Email: quantumbt0@gmail.com

2. Payment processing

Online payments on our store are processed through Stripe, a third-party payment service provider. Stripe helps process payment transactions securely and may support payment methods such as payment cards and other online payment options, depending on availability in your country and during checkout.

Available payment methods are displayed during checkout before you confirm your order. The final amount payable, including applicable product prices, taxes and delivery costs, is shown before the payment is submitted.

3. Card data security

When you pay online, payment card details are processed through Stripe’s secure payment infrastructure. Quantum BT does not store your full payment card number, card security code or full card authentication details on our website.

Depending on the selected payment method and technical setup, payment data may be entered directly into secure Stripe payment fields or a Stripe-hosted payment environment. This helps reduce the handling of sensitive card data by our online store.

4. Payment authentication

For security reasons, your bank, card issuer or payment provider may require additional authentication before approving a payment. This may include 3D Secure, Strong Customer Authentication or another verification step depending on your card, bank, country and payment method.

If authentication is required, please follow the instructions displayed during checkout or by your bank. If authentication fails or is not completed, the payment may be declined and the order may not be processed.

5. Payment confirmation

After a payment is successfully authorized or received, we may send you an order confirmation email. An order is processed only after the payment has been successfully confirmed and the order has passed our standard checks, including product availability and delivery information.

If payment is refused, cancelled, reversed or marked as suspicious, we may suspend, reject or cancel the order where permitted by law.

6. Currency and charges

Product prices are displayed in the currency selected on the website. Unless otherwise stated, prices shown to consumers include applicable taxes where required by law.

Delivery costs, if applicable, are displayed separately during checkout before the order is confirmed. Quantum BT does not intentionally add hidden payment charges during checkout. However, your bank, card issuer or payment provider may apply currency conversion fees, international transaction fees or other charges according to its own terms.

7. Payment errors

If a payment fails, please check that your card details, billing address, authentication step and available balance are correct. You may also try another available payment method.

If you believe that a payment was taken but your order was not confirmed, please contact us as soon as possible and include any available payment reference, order reference or screenshot of the payment status. Please do not send full card numbers or card security codes by email.

8. Fraud prevention and security checks

To protect customers and our store, payments and orders may be subject to fraud prevention, security and verification checks. These checks may be performed by Quantum BT, Stripe, payment providers, banks or other authorized service providers involved in the payment process.

We may contact you if additional information is needed to verify an order. If we reasonably suspect fraud, unauthorized use of a payment method, incorrect information or misuse of the website, we may refuse or cancel the order where permitted by law.

9. Refunds

If a refund is approved under our Returns & Refunds Policy, Right of Withdrawal, Warranty Policy or applicable consumer protection law, the refund will usually be issued to the same payment method used for the original transaction, unless otherwise agreed or required by law.

Refund processing times may vary depending on Stripe, your bank, card issuer or payment provider. After we process a refund, it may take additional time before the amount appears in your account.

10. Data protection

Payment processing may involve the processing of personal data, such as your name, email address, billing details, payment status, transaction reference and fraud prevention data. Payment data may be processed by Stripe and other payment partners according to their own legal, security and privacy obligations.

More information about how Quantum BT processes personal data is available in our Privacy Policy. More information about cookies and similar technologies is available in our Cookie Policy.

11. Payment provider terms

Stripe and other payment partners may apply their own terms, security rules, verification processes, privacy notices and compliance requirements. By choosing a payment method during checkout, you may also be subject to the terms of the relevant payment provider, bank or card issuer.
