I ordered a set of four cards, to track my both daily and travel items. They were all set up on my Andriod (Google Pixel), using their FindHub. I had trouble linking one card, and sent in an email. They were VERY quick to respond with an easy 'steps' email and it worked perfectly!
The cards are thicker than a credit card, but pretty much the same weight - still slid easily into the card holder of my small wallet.
I am excited to recieve the key tag, and will update this review when it arrives!

Was a Great Christmas gift. Delivery was fast within Europe and the quality looks solid. The rechargeable feature is good compared to other tags.

Bought an apple card and a Android card. Could not get Android card to connect to find hub. After proving to Rhinokey the faulty card via video and a number of email they sent a replacement. The replacement worked perfectly.

The Rhinokey works well so I’ve bought a few for Christmas presents for family this year

I purchased a pack of these to keep my various bags and belongings safe. I work for the NHS and I need to protect my work bag with my laptop and other sensitive documents so this is ideal to make sure that if it’s out of sight I can still find it. Brilliant invention!

ik ben heel blij met de rhinokey tijdens mijn reis door Afrika. Bedankt

I bought these to keep track of passports and wallets on an upcoming trip. I really like the idea of rechargeability, saving the need to replace batteries. They connected seamlessly to my iPhone, and as an added bonus the charger also charges my iPhone! Thanks, thes’ll make my trip much more enjoyable!

Ordered these to add to my luggage for a trip to South Africa. So easy to set up and link to my phone using the IOS system. Tracking was excellent and so useful that I now use one for my wallet and motorcycle and bought two more for my wife. I love the fact they are rechargeable and the batteries last quite a while. Not quite five months but I guess it depends how often you need to activate them for a location.

As someone who's always on the go in a bustling city like Ottawa, losing my wallet used to be one of my biggest fears—especially with essentials like my bank card, driver's license, and health card inside. That's why I decided to invest in the Rhinokey Smartcard, and I haven't looked back. In my two weeks with the Rhinokey Smartcard, it's delivered on its promise of worry-free organization. Carrying it with my essential cards has given me genuine peace of mind—I no longer panic if I can't spot my wallet immediately. The precise tracking and sound feature have been lifesavers, and the battery holding up after just one charge is a huge plus. Compared to other trackers I've tried in the past, this one stands out for its form factor and rechargeability. Setting it up was a breeze. I'm using it with my Google Pixel 9 on Android, and it pairs effortlessly through the Google Find My Device app (Find Hub). One note: the Android and iOS versions are distinct, so make sure to select the right one when buying. I appreciate that it works globally without any extra fees, which is perfect for travel.

Pros and Cons:

Pros:
-Slim and Discreet: Fits perfectly in wallets without bulk; ideal for minimalist setups.
-Excellent Battery and Charging: Rechargeable via wireless Qi—no more buying batteries.
-Reliable Tracking and Sound: Precise location, loud alert, and worldwide coverage.
-Ease of Use: Quick setup and intuitive app integration.
-Value for Money: Affordable, no subscriptions, and durable build.

Cons:
-Slightly thicker than a single credit card, so it might feel snug in very tight wallets (though it hasn't been an issue for me).
-Separate versions for iOS and Android—if you switch ecosystems, you'd need a new one.
-Charging indicator is a simple red light; no app-based battery percentage (though the app does show low battery alerts).

Overall, the pros far outweigh the minor cons, especially at this price point.

I just got my Rhinokeys and I have to say I am impressed. They are super easy to set up with my iPhone and so small I can tuck it in my purse and suitcase and forget about them. I am also impressed with the strength and durability of the Rhinokey. I am not nervous about it bending or being damaged in my bag.
I highly recommend the Rhinokey to anyone thinking of buying a tag.
