You know that panic that suddenly sets in when you reach into your back pocket to pay for a drink and find that nothing is there? Or you’re scrambling to get ready in the morning and find yourself driving on the way to work realizing you have truly no idea whatsoever where your wallet could be?

Chances are, you know that pain. Despite our best efforts, many of us still find a way to lose the thing that is arguably more important than anything: our wallet. If you’re a frequent misplacer of your own wallet, you may wonder what you can do to make that happen less often or make the search to find it take less time.

One of the best solutions to this age-old struggle is a wallet tracker. If you’re going to invest in one, though, you want to make sure you have a wallet tracker that you can trust to get the job done, and the wallet found.

Here’s a list of features that the best wallet tracker on the market will have.

1. All the Bells and Whistles

If you have ever gotten so desperate that you searched your freezer for your wallet, only to find your wallet under the couch, you need a tracker that will really make itself known. A good wallet tracker is one that will have a loud alarm to announce its own presence. Ideally, this sound should be pretty loud, as we tend to lose our wallets under or inside of things, where they can be difficult to hear.

The best wallet tracker will have not only a sound alarm but also a flashing LED light to make it easily visible if you can’t necessarily hear that alarm. This light should be intensely bright and flashy for the best visibility.

2. Solar Powered

Many wallet trackers are battery-powered. This can be great if the battery lasts a long time or is reusable, but you can never really know when you need it charged until it’s too late. That’s where having a tracker that’s powered by the sun can come in handy.

Solar energy is in pretty much an unlimited supply, and using a solar-powered tracker means you don’t have to remember to keep your tracker charged up or functioning on fresh batteries. Because if your tracker dies, it kind of defeats the whole purpose.

Plus, there is a huge push for more things to be solar-powered in general, and for good reason. Solar-powered means less energy is being used in the daily functioning of a product, so your wallet tracker is a greener choice as well as a practical one.

3. Trackable Worldwide

Have you ever forgotten your wallet in literally a different country? If you have, you probably all but assumed trying to track it down would be a lost cause. In most cases, you would probably be right. Even with most wallet trackers attached to your wallet, you can’t track it down outside of a certain mile radius.

But luckily, most doesn’t mean all. Though it may seem pretty unbelievable, the very best wallet trackers actually offer worldwide tracking. Very few even offer step-by-step directions in how to get to your wallet, so you’re not left taking a “warmer” or “colder” approach that makes the whole situation even more difficult.

Let Your Wallet Tracker Do the Work

If you constantly lose your wallet, you should invest in a wallet tracker. And if you’re going to invest in a wallet tracker, why not go ahead and buy one that offers as many features as possible. The best wallet tracker money can buy will offer you peace of mind that no matter where in the world you lose your wallet, you can trust that you’ll be able to find it.
