Credit Card Payments Information

We Accept Major Credit Cards

We accept all major U.S. credit cards to support fast, reliable, and professional purchasing for clinics, laboratories, treatment centers, staffing agencies, and businesses ordering diagnostic supplies. Our goal is to make online procurement simple, secure, and compatible with the purchasing systems organizations already use.

All card payments are processed through Stripe, a PCI-compliant payment platform trusted across the healthcare and technology sectors. Stripe uses strong encryption and secure architecture to ensure a smooth checkout experience while keeping your payment information protected. We never store or have access to your full card details—everything is handled within Stripe’s secure environment.

Below is an overview of the card networks we accept and how they fit into common purchasing workflows.

VISA

Visa is the most widely used card network among our business and medical customers. Because Visa is issued by nearly every major bank and credit union, it’s a dependable choice for organizations with multiple authorized purchasers or departments. Visa cards typically process quickly through Stripe and are commonly used for recurring supply orders, routine replenishment, and multi-unit testing kit purchases.

Mastercard

Mastercard is frequently used by small to mid-sized clinics, outpatient facilities, and businesses that manage consistent monthly procurement cycles. Many business debit and credit cards are on the Mastercard network, making it a practical option for teams who prefer centralized purchasing. Mastercard’s steady approval performance makes it ideal for standard restocks, scheduled orders, and predictable supply chain planning.

American Express

American Express is often preferred by organizations that handle larger budgets, consolidated purchasing, or detailed internal accounting. Amex’s clear statements and structured expense reporting make it useful for administrators managing multiple testing categories or higher-value diagnostic orders. Stripe supports Amex authorization smoothly, offering fast checkout for high-volume or specialized procurement.

Discover

Discover is a straightforward option for many U.S.-based customers. It provides reliable processing for standard restock orders and works seamlessly within our secure Stripe checkout. Buyers who prefer a simple, domestic-focused card network often choose Discover for routine medical supply purchases.

Security at Stripe: Learn how Stripe handles security.

A PCI-certified auditor has audited Stripe. We’re a certified PCI Service Provider Level 1. This is the most stringent level of certification available in the payments industry. To accomplish this, we use the best-in-class security tools and practices to maintain a high level of security at Stripe.

HTTPS and HSTS for secure connections

Stripe forces HTTPS for all services using TLS (SSL), including our public website and the Dashboard to ensure secure connections:

  • Stripe.js is served only over TLS.
  • Stripe’s official libraries connect to Stripe’s servers over TLS and verify TLS certificates on each connection.

We regularly audit the details of our implementation, including the certificates we serve, the certificate authorities we use, and the ciphers we support. We use HSTS to ensure that browsers interact with Stripe only over HTTPS. Stripe is also on the HSTS preloaded lists for both Google Chrome and Mozilla Firefox.

Sensitive data and communication encryption

All card numbers are encrypted at rest with AES-256. Decryption keys are stored on separate machines. None of Stripe’s internal servers and daemons can obtain plain text card numbers but can request that cards are sent to a service provider on a static allowlist. Stripe’s infrastructure for storing, decrypting, and transmitting card numbers runs in a separate hosting environment, and doesn’t share any credentials with Stripe’s primary services including our API and website.
