The short version.
A teen sells something — concert tickets, AirPods, sneakers — to a stranger online (Snapchat, Instagram, OfferUp, Marketplace). The 'buyer' sends a screenshot showing a Cash App, Zelle, PayPal, or Venmo payment confirmation. The teen ships or hands over the item; the money never arrives because the receipt was fake or the transaction was cancelled immediately. Variants include 'I overpaid, please send the difference back,' which results in the teen sending real money against a fake credit.
The platforms and contexts.
Snapchat and Instagram DMs for direct sales, Facebook Marketplace, OfferUp, eBay. The scammer is often from outside the buyer-network the teen normally uses.
The timeline.
Payment-app scams scaled with the apps themselves since around 2018. The 'fake receipt' specific variant became dominant around 2020 and continues.
The core facts a parent needs.
- Real payment confirmation has to appear in the actual app, not in a screenshot the buyer sends. Screenshots can be faked or use real but cancelled transactions.
- Cash App, Zelle, Venmo, and PayPal Friends & Family payments are generally non-reversible — but they're also fakeable. 'Send me the money back' from a fake overpayment is the most common loss vector.
- Payment platforms have very limited fraud-recovery options for peer-to-peer transactions. Teens often discover the loss is final.
What's actually at stake.
- Direct financial loss from goods shipped against fake receipts.
- Secondary losses from 'overpayment' return-the-difference variants.
- Cascading account exposure if the teen shared bank or payment-method details during the negotiation.
Concrete next steps.
- Set the rule: verify payment in the actual app, not from a screenshot. Wait for the app's own confirmation before handing over goods.
- Avoid Cash App / Venmo Friends & Family for transactions with strangers — those are not protected. Use Goods & Services or other protected categories when possible.
- If a scam has already happened, file with FTC and FBI ic3.gov. Recovery is rare but the documentation matters.
