Encryption at these ATMs is often not as good as at bank ATMs, meaning some locations are just not as safe. These ATMs also are more likely to be hacked. And in some cases, people have put up devices that look like ATMs but don't give out cash. Instead, they are just card-skimming devices aimed at stealing your credit card or debit card information.
Flea market merchants are often transient and can be difficult to locate if there is a problem with charges. It's especially true for vendors who don't have online credit card terminals and instead make carbon copies of your credit card.
That doesn't mean those vendors are necessarily fraudulent, but it makes the transaction less secure. The credit card company might have trouble doing a charge back. If you're going to the flea market, take cash. It's also easier to negotiate that way.

These smaller merchants have a significantly higher percentage of credit card fraud as reported by large banks and credit card companies. Many of these transactions end up being written off by the banks because the merchants simply can't be located. There's just a higher chance of fraud when you get outside of the mainstream, so when in doubt, use cash.

General common sense. Any safe, reputable e-commerce site is going to have a secure checkout page, like the one shown at left. If that doesn't appear, it should be a red flag.

If you're going to be making online transactions over an unsecured wireless connection like in cafes, parks and other hot spots, data can be compromised or seen while in transit, even if you're on a secure page while you're checking out. The same goes for public computers like in libraries. It's not advisable to ever transmit personal data when you're in a public connection environment, especially on non-secure wireless.
