Review: Works with DoorBird - I purchased these to create an easy way to unlock a DoorBird door system. Worked flawlessly. I am still trying to figure out where I can stick it on an iPhone case where it doesn’t get interference from the phone. But spots exist, you just have to be careful about where you stick it. Bottom line, works very well for my purposes. Review: Don’t buy - they don’t work - They do not work.

Worked flawlessly. I am still trying to figure out where I can stick it on an iPhone case where it doesn’t get interference from the phone. But spots exist, you just have to be careful about where you stick it. Bottom line, works very well for my purposes. ### ⭐ Don’t buy - they don’t work *by J***M on July 14, 2021* They do not work. Don’t buy ### ⭐⭐⭐⭐⭐ Worked for Hornady RAPiD Safes *by P***N on February 14, 2022* I bought this since all of the RFID tags that Hornady includes with its RAPiD series of safes are fairly bulky. This worked perfectly. Nice and thin so I just stuck it to the back of my phone. Recognized immediately by my safe, and adding it was the same process as adding any Hornady RFID key. Works fine through my phone case as well. ## Frequently Bought Together - 125KHZ EM4100 RFID Soft Paper Sticker Dia 30mm Read Only (Pack of 10) - 125 khz RFID Sticker,PVC Material 1mm Thick id Coin Key fobs (Pack of 10) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/116733557-125khz-em4100-rfid-soft-paper-sticker-dia-30mm-read-only](https://www.desertcart.co.za/products/116733557-125khz-em4100-rfid-soft-paper-sticker-dia-30mm-read-only) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-14*
