Eindhoven, along with the rest of the Netherlands has a relatively low crime rate, and you should not run into any problems whilst traveling throughout the area.

As with any locale you are unfamiliar with, it pays to be alert while traveling within large crowds, especially during the high season. Pickpockets can quickly pick you clean of your money or passport, quickly turning a dream vacation into a nightmare. Make use of your hotel's safe to protect items such as any jewelry you might have brought with you (which, in reality, is best left at home), extra monies, credit cards, and passports. Keep your eyes and a hand on bags at all times, and do not leave your items unattended. If you are backpacking, bring along a lock that you can use to lock your backpack to a bed or other sturdy piece of furniture in your room. You will also want to use minilocks to keep your zippers locked together.

Keep a copy of the front page from your passport, any tickets, and any other important information in a location separate from the originals. You may also consider leaving a copy of these pages with someone back at home, whom you can contact if necessary if you get into trouble abroad. These copies will come in handy if you are a victim of theft.
