Verification of payments

Letzshop has subscribed to the online payment services of Stripe

In order to limit the risk of fraud , this service provider undertakes multiple verifications of payments before their validation:

  • Any amount exceeding €100 will automatically be secured by 3D Secure validation technology (SCA).
  • Amounts below €100 are generally exempt from this check in order to facilitate online purchases. However, an additional check may take place on a random basis.

Stripe Radar

Stripe Radar is a fraud detection and prevention solution provided by the payment service provider Stripe.

It analyzes all payments made via Stripe in real time using artificial intelligence (AI) and hundreds of features/signals to assess whether a transaction is likely to be fraudulent.

Based on this risk, Stripe can automatically block high-risk payments or flag them for manual review. 

For each payment, Radar calculates a risk score.
Transactions with a high risk (e.g. suspicious IP address, implausible card or address data, unusual purchase patterns, etc.) are automatically blocked.

Radar uses data from the entire Stripe network — meaning millions of transactions worldwide — to identify fraud patterns.

Procedure for cards

If a payment card holder opens a dispute with the card issuing institution, the following procedure will follow: 

  • Bank opens dispute file with Stripe.
  • Stripe will request transaction details from the merchant.
  • Stripe will forward these documents to the payment card issuing institution.
  • The issuing institution will evaluate the documents and decide whether the transaction is to be considered legitimate or fraudulent.
  • If applicable, the issuing institution will ask Stripe to cancel the transaction in order to reimburse the cardholder.
  • Stripe will reverse the transaction and remove the amount charged from the merchant account.

Procedure for PayPal or Amazon Pay

With PayPal, the customer can request a refund within 180 days.

With Amazon Pay, the customer can request a refund within 75 days.

The procedure is as follows: 

  • Customer opens a case with Stripe.
  • Stripe forwards the case to Letzshop.
  • Letzshop forwards the case to the retailer along with the reasons provided by the customer.
  • The retailer has between 7 and 14 days to file an objection.
  • If the customer wins the case, the money will be refunded to them. Additionally, penalty fees must be paid to PayPal or Amazon Pay. The retailer will not receive any payout.
  • If the retailer/Letzshop wins the case, the retailer will receive their payment as usual.

“Click&Collect” prevention

To reduce the risk of fraud, please follow these recommendations when collecting goods ordered via “Click&Collect”:

  • Validate that the data of this person corresponds to the data stipulated in the order details
  • Do not pass on the goods to a person whose identity data does not match those on the order.
  • In all cases, please have a removal slip signed by this same person.
  • Please keep this removal slip together with a copy of the invoice for your records.
