How can a store protect digital payments from fraud?

Protect payment accounts with strong passwords and two-step verification, and never share verification codes with anyone. Don’t ship any order until you have confirmed the money has actually reached your account, not from a photo of a receipt. Decide who may receive and refund payments, and review transactions daily to catch any discrepancy early.

The most common frauds against stores

Fake payment receipt: An edited image of a transfer receipt, sent to rush shipping before the money arrives.
Request for the verification code: Someone posing as the service provider or a customer asks for the code you received by text.
Overpayment and refund request: The fraudster claims to have paid more than required and asks for the difference back, then it turns out the original payment never happened.
Hacked accounts: Messages from a known supplier’s or customer’s number asking for payments to be sent to a new account.
Fake login links: A message that seems to come from the service provider asks you to log in through a link to confirm the account or receive money, and the link steals your login details.

Protecting the store’s accounts

One account per staff member: Don’t share one password between everyone. Each person has their own account and permissions.
Two-step verification: Turn it on for email, payment accounts, the online store and WhatsApp Business.
Separation of duties: The person who receives payments should not be the only one who approves refunds or changes account details.
A protected work phone: The phone that receives payment messages needs a strong lock and is never lent to anyone.

Protecting the customer too

Fixed, published payment details: Publish your official payment channels on your website and page, and tell customers you never change them by message.
Don’t ask for sensitive data: Never ask a customer for a password, a verification code or a full photo of their card.
Consistent confirmation messages: Use a fixed format for confirmation messages so customers can spot fake ones.
A reporting channel: A clear number or email where customers can report any suspicious message sent in your store’s name.

Frequently asked questions

Is a photo of a receipt enough proof of payment?

No. Proof is the amount appearing in your account or a confirmation from the service provider itself.

What should I do if I shared a verification code by mistake?

Change your password immediately, contact the service provider to stop any transaction, and review the latest activity on the account.

Does a small store need security measures?

Yes. Small stores are easy targets because their procedures are weaker, and the simple rules in this article are enough for a good start.

How do I train my staff on this?

Go through real examples of fraud messages together, and write short rules to post near the till or pin in the team group.

Does an internet outage affect security?

It can push staff to skip verification because they are in a hurry. Write a clear rule: nothing is handed over before confirmation, even if confirmation is delayed by the network.
