Seinxon Wallet Finder: the headline says GPS, the spec sheet says Bluetooth

A credit-card-shaped tracker that sits in a wallet and reports its position through Apple’s Find My network. Two Kickstarter campaigns, both funded many times over, and a product on open sale today. The campaign’s own headline and its own subtitle describe two different technologies, and that is worth knowing before anything else.

Maker: Seinxon, New York, NY. Kickstarter creator account in the name of LianZhi Du
Price: US$21.99 for the Wallet Finder “Precious” single pack, marked down from a US$35.00 regular price on the maker’s own store. Confirmed on 7 August 2026 and may change.

The headline says GPS. The subtitle says Bluetooth.

The 2022 campaign is titled “Seinxon: The #1st APPLE GPS Finder(CARD)”. Directly beneath that title, on the same page, the campaign’s own summary line lists its features separated by vertical bars, and the third of them reads “Buletooth 5.0” — the maker’s spelling, not ours.

No published specification we found — on the campaign, on the product page, or on the maker’s Amazon listing — names a GPS receiver. The product page for the unit sold today says “Works with Apple Find My”. That is a network of other people’s iPhones reporting a Bluetooth signal, not satellite positioning. The practical difference matters to a buyer: a Find My tag is silent where no compatible phone passes, and it has no position of its own to report.

The point is narrow: the word in the campaign title is not supported by any specification the maker publishes, including the one printed immediately below it. As a Find My tag, the product does what its product page says.

Two campaigns, and where each one stands

Sources: the two campaign pages linked above and the creator page, all read on 7 August 2026.

The 2022 campaign promised shipping from January 2023, and the outcome is not in doubt: the product is on open retail sale, it has an Amazon listing, and 1,356 comments remain readable on the campaign page.

The 2025 campaign is the one to watch. It closed on 12 July 2025 and Kickstarter still shows it as “Marked as in fulfillment” on 7 August 2026 — roughly thirteen months later, with eight updates posted and the most recent dated 2 March 2026. That is not evidence of failure. Hardware slips, and eight updates is more communication than many campaigns manage. It is simply the current state, and a reader deciding today should know it.

What the maker publishes about the unit on sale

Two things about this table are worth drawing out.

The thickness figure is not consistent across the maker’s own material. The product page gives 0.07 inches, which is 1.8 mm. Marketing copy for the Finder Card elsewhere states 1.6 mm. These may be different models — the range includes Pro, Pro Max, Mini and Mate variants, but the pages do not make that distinction plain, and 1.6 is the figure that reaches search results.

The 2022 campaign subtitle advertises “iOS x Android” and “RFID”. The product page for the unit on sale today lists neither. The maker’s own Amazon listing carries “(iOS Only)” in the product title. Android support and RFID blocking appear to belong to other products in the range, not this one.

Who has written about it from outside the company

Less than the review count suggests, once each source is opened.

• An anonymous post at Critical Bears, dated 12 December 2022, disputes the campaign’s “first” and “GPS” claims, naming Chipolo, Tile and Pebblebee as prior card trackers. The post is unsigned and gives no indication its author had a unit. We are citing it because the GPS point is checkable on the maker’s own pages, which we have done above — not because an anonymous post is evidence in itself.
• A piece at DBT Bureau dated 6 July 2024 is bylined to “DBT Bureau” rather than a named writer, restates the maker’s specifications, reports no measurements of its own, and carries no disclosure.
• Two video reviews exist on YouTube.
• The star ratings that dominate a search for this product are customer reviews on the seller’s own shop, served by Judge.me, a review app a merchant installs on its store. Those are buyers’ opinions collected by the seller, not independent journalism.

We did not find a review by a named writer at a publication with editorial staff who had the product in hand. For a product with more than 2,800 backers across two campaigns, that is a thinner record than we expected.

Pros

• Two funded campaigns, and the first one shipped and reached open retail
• IP68 to 3 metres for up to an hour, stated against IEC 60529 rather than as a bare badge
• Wireless recharging rather than a sealed battery that ends the product’s life
• A stated 12-month warranty and 30-day guarantee
• The campaign pages, comments and updates are all still open to read

Cons

• The 2022 campaign title says “GPS” and no published specification supports it; the same page’s subtitle says Bluetooth
• Campaign features “iOS x Android” and “RFID” do not appear on the product page for the unit on sale; the Amazon listing says iOS only
• Published thickness differs between the maker’s own pages
• Weight, Bluetooth version and range are absent from the product page
• No review by a named writer with the product in hand that we could find
• The 2025 campaign has been in fulfilment for roughly thirteen months
• The six-month battery claim: no source we read has run a unit down and reported the result

Where this leaves a buyer

At US$21.99 this is a sensible buy if you want a card that rings from inside a wallet on an iPhone. It is the wrong buy if you read “GPS” in the campaign title and expected satellite tracking, or if you are on Android: this model is Find My only.

FAQ

Does it use GPS?
Nothing the maker publishes says so. The product page says it works with Apple Find My, which locates a tag through nearby iPhones over Bluetooth. Treat the campaign title as marketing language rather than a specification.

Does it work with Android?
Not this model, as far as we can tell. The product page names only Apple Find My, and the maker’s Amazon listing says iOS only. The 2025 wallet is the product advertised as supporting both platforms, and that one is still shipping to backers.

Did the Kickstarter backers receive it?
For the 2022 campaign the evidence points that way: 26 updates, 1,356 comments still standing, and open retail sale since. The 2025 campaign is still marked as in fulfilment.

Is US$21.99 the real price?
It is the price shown on the maker’s store on 7 August 2026, marked down from US$35.00. Check before you buy.
