Fraud Prevention and 3D Secure for Info Product Businesses
The card fraud course and coaching sellers see, why low-price offers attract card testing, the 2026 network limits, and where 3D Secure helps.
Article summary
TL;DR
Course and coaching sellers see three kinds of card fraud: card testing on low-price offers, stolen cards on expensive programs, and buyers who use the course and then claim fraud. Protect cheap offers with CAPTCHA and rate limits, ask for 3D Secure on risky high-ticket orders, and log every access: dated logins and IP addresses answer a fraud claim best.
- Stripe: card testers create "small amount payments, which cardholders are less likely to notice and report as fraudulent" (read November 2, 2026).
- Visa's VAMP counts fraud reports plus disputes; the US "Excessive" level is 1.5% and 1,500 cases since April 1, 2026.
- Mastercard's EFM applies above 0.50% fraud chargebacks when 3D Secure covers 10% or less of payments.
- 3DS liability shift "isn't guaranteed", and off-session renewals don't support 3DS.
- For digital goods, Visa accepts proof such as IP address, device ID and access to your site on or after the purchase date (rules of October 24, 2026).

Fraud an info product business sees
A course has no warehouse and no shipping delay. The buyer gets access in seconds, so fraud has to be stopped at the payment, or proven afterward with access data.
| Type | What it looks like | First defense |
|---|---|---|
| Card testing | Bursts of small payments on your cheapest offer, nonsense names and emails2Stripe Docs, Protect yourself from card testing, read November 2, 2026 | CAPTCHA, rate limits, block rules |
| Stolen card on a high-ticket program | New buyer, high-ticket order, card country and IP don't match | 3D Secure, manual review before access |
| Access resale | One account used from many devices and countries | Device limits, login alerts |
| Friendly fraud | The buyer finishes the course, then reports the charge as fraud | Access logs, Order Insight with CE 3.07Stripe Docs, How dispute prevention works, section Compelling Evidence 3.0, read November 2, 2026 |
| Someone else's card | A partner or parent pays, the cardholder disputes | Billing name on receipts, clear descriptor |

Card testing on low-price offers
A low-price ebook or tripwire is the perfect target: a small charge that cardholders rarely notice2Stripe Docs, Protect yourself from card testing, read November 2, 2026. Stripe lists the consequences: disputes and Early Fraud Warnings, higher decline rates for your real buyers, extra fees, and possible card monitoring programs2Stripe Docs, Protect yourself from card testing, read November 2, 2026.
Signs to watch, per Stripe2Stripe Docs, Protect yourself from card testing, read November 2, 2026:
- A spike in failed or blocked payments.
- A spike in generic declines.
- Many low-amount payments with "nonsensical customer names and emails".
Defenses Stripe recommends2Stripe Docs, Protect yourself from card testing, read November 2, 2026:
CAPTCHA
On every request that can validate a card or make a payment.
Rate limits
Such as a cap on new customers per IP address per day.
Limits on cards per account
And purchases of the same product.
Refund suspicious payments
That get through, to avoid disputes.
Stop retrying
Cards saved by fraudulent customers after an attack.
Watch out
Opt-in pages and free trials that save a card are also targets. Stripe says card setup is the method "preferred by fraudulent actors" because validations don't usually show on statements2Stripe Docs, Protect yourself from card testing, read November 2, 2026.
The fraud limits that apply
1.5%
Visa VAMP ratio for US merchants, with 1,500 cases
300,000
Card testing attempts for Visa's enumeration level, with a 20% ratio
0.9%
Visa Secure Excessive Fraud ratio, with $75,000
0.50%
Mastercard EFM fraud ratio, with 3DS on 10% or less
A fraud report counts even if you refund: issuers must report possible fraud on a captured payment, refunded or not1Stripe Docs, Dispute and fraud card monitoring programs, read November 2, 2026. What isn't reported is a suspicious authorization you reverse before capture1Stripe Docs, Dispute and fraud card monitoring programs, read November 2, 2026.
Tagada follows Visa and Mastercard rules and the laws that apply to payments.
What 3D Secure does, and doesn't
European buyers. Strong Customer Authentication is "a European regulatory requirement", and payments that don't follow it "may be declined by your customers' banks", as Kajabi tells its creators8Kajabi Help Center, How Kajabi supports payment authentication, read November 2, 2026. If you sell to the EU or UK, 3DS is part of the checkout, not an option.
Fig. 2A payment plan: 3DS covers the first payment, not the next ones
First payment, at checkout

Eligible fraud liability typically moves to the issuer
Later installment
- InstallmentOff-session
- chargesSaved cardCharged without the buyer, no 3DS
No 3DS: your terms and logs are the protection
Later installments run without the buyer, so ask for 3DS when the card is saved.
Where to ask for 3D Secure
- High-ticket programs and coaching, where one stolen card costs you the whole price.
- First payment of a payment plan, since later installments run without the buyer.
- Card country, IP and billing country that don't match.
- Several cards tried from one device or one email.
- Soft declines where the issuer asks for authentication.
- Not returning buyers with a clean history: a challenge on a small upsell costs you sales.
Legitimate buyers who still get declined: reducing payment declines for info product businesses.
Instant access: when to deliver
Most info products deliver on payment. For the expensive ones, a short pause is worth more than speed.
- Authorize the card at checkout for high-ticket orders flagged by your rules.
- Review the order: name, email domain, IP country, card country, past purchases.
- Capture and grant access if it checks out.
- Void the authorization if it doesn't. Fraud found before capture isn't reported1Stripe Docs, Dispute and fraud card monitoring programs, read November 2, 2026.
- Stay inside the window: an online authorization started by the customer lasts 7 days on Visa and Mastercard, per Stripe5Stripe Docs, Place a hold on a payment method, read November 2, 2026.
Fraud found before capture isn't reported; the authorization lasts 7 days.
Kajabi's advice after an Early Fraud Warning applies too: "we recommend revoking access to the content that was purchased"9Kajabi Help Center, What is a payment dispute, updated September 28, 2026.
Friendly fraud: access is your proof
A buyer who watched every lesson and then says "I didn't make this purchase" is the most common fraud claim a course seller can win. Visa's evidence rule for digital goods asks for a description, the date the service was provided, and two or more items such as6Visa Core Rules and Visa Product and Service Rules, edition of October 24, 2026, table 11-7 (Compelling Evidence, item 4):
- IP address and device ID.
- The buyer's name and email linked to their account with you.
- Proof the buyer's profile was accessed and verified before the purchase.
- Proof your site was accessed by the cardholder on or after the purchase date.
- The same device and card used in an earlier undisputed payment.
With Order Insight, CE 3.0 can block the dispute before it's filed when two earlier payments match on IP address and email7Stripe Docs, How dispute prevention works, section Compelling Evidence 3.0, read November 2, 2026. That's why every payment, renewal and installment should carry the buyer's IP and email. More: chargeback alerts for info product businesses.
