In my case it was luggage. Suitcases and backpacks all look the same once they’re on a conveyor belt or stacked in a hallway. The usual paper tags tear off, cheap plastic ones break, and even if they survive, nobody actually reads the tiny text unless something goes wrong. I wanted something different: - a tag that is **visibly mine** (not just a discreet little label), - a way for someone to contact me if they find my bag, - a way for me to manage multiple tags without being locked into one ecosystem, - and a solution that isn’t restricted to the Apple universe. That’s how **Bag-Tag.de** started. In this post I want to tell the story behind it, show how it works from the user’s perspective, and share a few thoughts about where it fits compared to things like AirTags. ## Why I didn’t just buy another AirTag AirTags are great for what they are: tiny location beacons that piggyback on the Apple device network. But they come with a few constraints: - they live fully inside the Apple ecosystem, - they are invisible unless you know they’re there, - and they solve a different problem: “where is this thing?” – not “who does this belong to and how do I contact them?”. I was looking for something else: - a tag that is **obviously visible** and stands out on a bag, - a **simple contact flow** if someone finds it (scan, see info, get in touch), - a small **web-based backend** where I can manage multiple tags under one account, - and the freedom to use it regardless of whether I or the finder are on iOS, Android or something else. So instead of trying to bend AirTags into something they’re not, I decided to build a system that’s deliberately simple, visible and web-first. ## What a Bag-Tag actually is A Bag-Tag consists of two pieces: 1. a physical tag that you attach to your bag (with a bold, high-contrast design so it stands out), 2. a small online profile that lives behind a QR code or short URL. The idea is: - you customise the tag once (design, colours, maybe a name or icon), - you attach it to your luggage, backpack, instrument case, kids’ bags – whatever you want, - if someone finds your bag, they scan the code or open the URL and see exactly the information you chose to share, - you can update that information later without reprinting the physical tag. This is what a tag page looks like right now (simplified): - a clear heading with the tag ID or name, - some key information about the item (optional), - contact options (for example an email form or other contact channel), - and whatever extra hints you want to show (e.g. “this belongs to a child”, “medical equipment”, etc.). From the outside it’s “just” a QR + website combo. Under the hood there’s a bit more structure. ## Managing multiple tags with one account One of the design goals was: this should scale beyond a single suitcase. So Bag-Tag.de lets you create an account and manage multiple tags from one place: - you can register several tags (for different bags, family members, use cases), - give each tag its own label and contact info, - and see which tags are active. Internally, each tag has a unique ID and is connected to your account. The public URL (like the example you’ve seen) only shows what’s necessary to help the finder reach you – nothing more. This separation is important: if you lose a bag, you want people to reach you easily. But you probably don’t want to dump all your personal details directly on a piece of plastic that can be photographed and posted anywhere. ## Why the tags are deliberately not subtle I didn’t want Bag-Tags to be “just another discreet accessory”. I wanted them to be visually loud enough that: - you can spot your bag quickly on a conveyor belt, - other people notice there is a tag they can interact with, - and it feels more like a statement than a hidden technical gadget. That’s why the designs on the homepage look bold and colourful rather than minimal and grey. In a sea of anonymous black suitcases, a tag that pops is a feature, not a bug. From a very practical perspective it means: - you see your stuff faster, - you reduce the chance that someone grabs your bag by mistake, - and if something gets lost, the person who finds it has a clear visual signal: “scan me, there’s more info here”. ## How this compares to AirTags and friends This is not meant to compete with AirTags – it’s solving a complementary problem. **AirTag / similar:** - “I don’t know where my bag is right now; show me its approximate location on a map.” - Works via Apple’s network of devices. - Great for tracking something that may be far away or stolen. **Bag-Tag.de:** - “This bag is physically here, someone has it in front of them; how do they know who I am and how to reach me?” - Works for anyone with a camera and a browser. - Great for everyday mistakes: wrong bag taken, bag left behind, kids’ bags, shared spaces. I actually see them as complementary tools: - if you’re deep in the Apple ecosystem and you want geolocation, an AirTag makes sense, - if you want a clear, platform-independent way for people to identify and contact you about your bag, a Bag-Tag is a simple, low-tech layer on top. And if you really care, you can use both. The tag doesn’t care whether there’s an AirTag hiding inside the suitcase as well. ## Implementation thoughts (for the tech-curious) This blog isn’t a full technical deep dive into Bag-Tag.de, but a few pieces might be interesting if you’re a developer: - Each tag is essentially a record in a database with a unique ID and a set of fields (owner reference, display name, contact options, status). - The public-facing URL resolves that ID, loads the minimal data needed and renders a simple, mobile-friendly page. - The owner side is an authenticated dashboard where you can: - see all your tags, - edit what’s shown on each tag page, - deactivate tags if they’re lost or no longer needed. The interesting part for me was less the tech stack (it’s fairly standard web tech) and more the balance between: - giving finders enough information to help you, - and giving you enough control so you don’t overshare by default. ## Where I want to take it next Right now, Bag-Tag.de is deliberately simple. That’s a feature, not a limitation. Possible future ideas I’m thinking about: - optional notifications when someone visits a tag page, - temporary messages on a tag (“I’m travelling, please use email instead of phone”), - different profiles for different contexts (work, personal, kids), - integration with simple automations (e.g. logging when a tag was scanned). But even in its current form, it already does the thing I wanted from the beginning: - my bags are easier to spot, - people have a clear way to reach me if something goes missing, - and I’m not locked into a single vendor ecosystem. If that sounds useful to you, you can see a live example here: - [Bag-Tag.de](https://bag-tag.de/?ref=blog.bajonczak.com) – homepage with tag designs - [Example tag view](https://bag-tag.de/5ea2a017-8976-4d28-a2c0-6c80395858a7?ref=blog.bajonczak.com) – how a tag looks when someone scans it And if you end up creating your own tags, I’d be curious to see where they end up in the world.
