Secure Payment Methods for Online Auctions

Payment fraud is one of the biggest security risks for nonprofits raising money online. Scammers bid on items using fake transactions or stolen cards, hoping organizations do not catch it before items are fulfilled. According to CharityAuctions.com platform data, more than 50,000 organizations have used CharityAuctions since 2007. Most auction platforms use secure payment processing. Knowing why your payment method is secure helps reassure your board and donors. See donor privacy in charity auctions for related data protection guidance.

Why large scale payment processors are more secure

It is safer for auction platforms to use a third party processor or digital wallet instead of processing payments themselves.

Think of major processors as a heavily guarded vault at a large bank. They are constantly tested by sophisticated criminals but nearly impossible to breach because of layers of security, 24/7 monitoring, and large investments in protection.

Smaller, unknown auction platforms are like a safe in a small office. They are not targeted as often, but they are much more vulnerable if someone tries.

How tokenized payment processing works

Platforms using third party processors use tokenization. Actual credit card numbers never get stored in the auction platform database.

Even if your platform asks donors to pre register a card before bidding, that information is stored as tokens. Hackers may target auction platforms to steal payment data, but they would not find real financial information if they got in.

How it works:

1. A donor enters their card information on your auction site.
2. The card information is sent securely to the processor. It is never stored in the platform database.
3. The processor verifies the card and processes the payment using their secure, PCI DSS Level 1 certified infrastructure.
4. The processor sends back a token, a random string of characters that represents the donor's payment method.
5. Your auction platform stores only this token for future transactions.

The most secure payment methods for charity auctions

1. Third party processors

Payments through a trusted processor are significantly safer than platform stored payments. This includes credit card, debit card, direct ACH transfers, and digital wallet payments.

Examples:

• Stripe
• Authorize.net
• PayPal
• Square
• Deluxe and iATS
• CardConnect

Beyond basic security, established processors have fraud detection that flags suspicious transactions. They handle currency conversions for international donors and stay up to date with new security standards.

2. Digital wallets

Many donors bid on their phones. Auction platforms now offer mobile payments through trusted digital wallets. These mobile payments are secure when done through trusted digital wallets.

Examples:

• Apple Pay
• Google Pay
• Samsung Pay
• PayPal

When a donor uses Apple Pay or Google Pay, they do not enter credit card information on your site. The wallet opens on their phone, asks for their password or fingerprint, and the payment is processed. This uses tokenization, so the transaction is secure.

Payment methods to avoid

Direct card storage. If an auction platform stores credit card numbers or bank information in their own database, walk away. Most auction platforms are not as secure as trusted payment processors.

Unknown payment processors. A processor with little reputation might save money, but can you verify their security credentials? If not, you are gambling with donor financial data.

Manual payment handling. Collecting credit card numbers over the phone, via email, or through unsecured forms creates multiple points of vulnerability.

Peer to peer apps like Venmo and Cash App. They can be used safely, but they have fewer fraud protections and are less regulated than certified payment processors.
