A really good fraudster nearly convinced me he made a legitimate payment for my Rolex Sprite. Everything checked out. Payment cleared to my bank account. I had his driver's license. The ID matched the shipping address.

But one thing didn't stack up.

My payment processor flagged the transaction because the order was placed in Brazil. Nearly 4,200 miles away from the shipping address in Florida.

I asked him why the card was run in Brazil. He said he was there temporarily and returning home shortly.

I called my processor. They told me this specific card was tied to multiple fraud attempts in the past.

Then it got worse.

The funds that dropped into my account? Automatically reversed 24 hours later.

If I had shipped that watch, I'd be out $18k with no recourse.

Fortunately, the watch hadn’t shipped.

Here's the lesson: if you're selling high-value items without tools to prevent chargebacks and fraud, you're one smooth talker away from a very expensive mistake.

What are you doing to prevent fraud in your business?
