The Bauhn Smart Tag Card (Model: AASTC) is a sleek, wallet-friendly alternative to traditional trackers, designed specifically for those within the Apple ecosystem. Below is an overview of its key features and specifications to help you structure your review.
The Bauhn Smart Tag Card is a slimline tracking device engineered to fit seamlessly into wallets, passport holders, or laptop bags. Unlike the standard coin-shaped trackers, its card-like form factor makes it nearly invisible when tucked away, yet it packs the same powerful tracking capabilities.
Key Features
- Apple ‘Find My’ Compatible: It integrates directly with the Find My app on iPhone, iPad, or Mac. You don’t need a third-party app; it leverages Apple’s global network of millions of devices to help you find your items.
- Track & Locate: Use the app to see your card’s last known location on a map or play a sound through the built-in speaker to find it when it’s nearby.
- Smart Notifications: Receive “Left Behind” alerts if you walk away from your wallet, ensuring you never leave the house without your essentials.
- Rechargeable Battery: A standout feature compared to many disposable card trackers. It features a 155mAh internal battery, rechargeable via wireless charging.
- Rugged Build: With an IP68 rating, the card is fully dust-tight and can withstand being submerged in water (typically up to 1.5m for 30 minutes), making it resilient against spills or rainy weather.
- 1 Year Warranty

Here is a pros and cons breakdown.
Pros and Cons
| Pros | Cons |
| Eco-Friendly & Cost-Effective: The wireless rechargeable battery means you aren’t buying a new tracker every 12–24 months. | No UWB (Ultra-Wideband): Unlike AirTags, it lacks “Precision Finding” (the arrows that lead you exactly to the inch). |
| Wallet-Ready Form Factor: At roughly the size of a credit card, it fits in card slots where a bulky AirTag won’t. | Availability: Being an Aldi “Special Buy,” it can be difficult to find once the initial weekly stock sells out. |
| Superior Weatherproofing: The IP68 rating is higher than many competitors, offering peace of mind against heavy rain or spills. | Speaker Volume: Slim card trackers generally have quieter speakers than thicker, puck-style trackers. Similar cards have a 80dB rating. |
| Native Integration: No extra apps required; it works exactly like an Apple-branded product within the “Find My” app. |
The Verdict
The Bauhn Smart Tag Card (AASTC) is a decent option for any iPhone user who shops at Aldi. While it lacks the high-end Precision Finding (UWB) found in Apple’s own AirTags, its rechargeable design and slim profile make it a superior choice specifically for wallets.
If you want a low-maintenance, set-and-forget tracking solution that doesn’t create electronic waste via disposable batteries, this is one of the best value accessories currently available on the market.
Alternatives
