If you’re a frequent traveler, you may already own a tracker for your bags or a TSA lock to protect your things. But one aspect of traveling safely with luggage is, I would argue, underlooked: the luggage tag. All of your personal information, written out for anyone who comes across your suitcase to read? No thank you. That’s where investing in a smart luggage tag can provide some peace of mind.While having a luggage tag with your contact information is important for identifying your bags and getting help when they get lost, you don’t need all of your personal details out in the open the rest of the time. Dynotag’s SuperTagID solves this problem, and reviewers say it’s a “stroke of genius” that “makes me feel better about my luggage.”The difference is that this smart tag, made of sturdy anodized aluminum, uses a QR code that a person who comes across your luggage will have to scan to see your info in order to contact you, meaning it’s not written out where anyone can read it. Sure, you may have seen luggage tags that simply hide the information card under a flap, but the SuperTagID adds another layer of security: Any time that QR code is scanned, you’ll get an email notification that also gives you the approximate GPS location of the device that scanned it so you can more easily get reunited with your luggage. (Just bear in mind that the tag itself is not a tracker, so you’ll likely still want to use one for your bags just in case.)“This tag was a lifesaver!” said one reviewer, who explained that, when luggage was lost on their daughter’s school trip, incomplete information on her classmates’ tags prevented some of them from being able to claim their own bags, and their parents had to come pick them up themselves. Meanwhile, the smart tag lets you add more information than a standard luggage tag, and can be updated in real time. If you buy multiple tags, you can set up unique IDs for each or use the same common ID record for all of them. That reviewer continued, “Before she left, I updated the information to reflect her name, address and phone number, so that she could claim the luggage with her school ID. But the information on the tag was not viewable unless you scanned the tag. And every time the tag is scanned, you get an email to alert you someone is scanning the tag!” They added, “This was a lifesaver in today’s age where you don’t want your name, address, and phone number visible to just anyone, but you still need to be able to claim something as yours!”AmazonThe tag comes with a unique link and QR code so people only get access to your information when it’s necessary.With the SuperTagID, you can add information like your name and phone number, but also multiple addresses and other forms of contact, including social media. You can even add a photo to make it easier to claim your luggage. If the person who finds your lost luggage doesn’t have a QR code reader, there’s also a unique web address printed on the tag. The tag can be set up, updated and scanned on any Internet-connected device: no subscription, no added fee and no separate app. And for emergencies (like if there’s no Internet connection available), there is still a paper information card that you can fill out and then conceal on the inside.Plus, reviewers are impressed with the physical tag itself. “I’ve had several tags over the years. So many of them are made from very cheap materials and need to be replaced every few trips,” said one person. In contrast, the SuperTagID is “sturdy and impervious to weather.” The tag is secured to your bag using a braided steel loop; some reviewers recommend using glue or a zip tie for extra security. The reviewer continued, “One of the other great things with this tag is that since most people aren’t using them it also helps to make identifying your luggage even easier at the end of your flight.” You can choose from six colors, many of which are bright and eye-catching, like red, blue and orange.Below, check out more promising reviews from people who have used this smart tag for themselves. If you ask me, $20 is a pretty small price to pay for peace of mind.“I love that I can put these tags on my luggage without revealing all my personal information. The sturdy construction means that can stand up to the abuse of being tossed around during baggage handling. It’s great that someone can use the QR code to notify you that your luggage has been found without revealing all of your personal information.” — K A“Tags are sturdy aluminum and brightly painted for quick identification. The free webpage that links the tags to you is easy to navigate. No batteries or signals to interfere with plane systems makes them welcome on luggage going anywhere in the world.” — Dan“I love this product. I am going on vacation and will both fly and take a train to my destination. These tags will go on my luggage so that it can be located if lost en route. Having had my luggage lost in the airport in NYC was a near disaster and these tags would have located them easily. Peace of mind is a wonderful thing!” — Tommie Slayden“This is a great alternative to traditional luggage tags. Not only is it sturdy and impervious to weather, but I much prefer having my contact information guarded by a QR code than to have my address and phone number on display to everyone hanging around the baggage claim carousel at the airport. I got one for myself and another for my spouse. They were easy to set up. I highly recommend them for frequent travelers.” — Lisa N.“Durable luggage tag that is also discreet. Also comes with a metal band to securely attach the tag to your suitcase. The setup is easy, just enter the information you want the finder to view on the Dynotag site. It makes me feel better about my luggage in the event it gets lost.” — GraemeLooking for more ways to stay safe while you travel?
