Review: Excellent value - both chips work fine with Flipper Zero - I needed to duplicate a Schlage 9691T dual chip key fob, and these work perfectly. Following are notes: 1) The NFC chip does read as a Gen 1a "Magic tag" with the Flipper Zero 2) The Flipper Zero had no trouble successfully writing (duplicating) to the 13.6 MHz NFC chip 3) The Flipper Zero had no trouble successfully writing (duplicating) to the 125 kHz RFID chip I am very happy with these. I don't understand the number of bad reviews, and assume that most of the bad reviews are due to user error or user misunderstanding of how these protocols work.
Review: Very good item - Very good it work good

### ⭐⭐⭐⭐⭐ Very good item
*by A***I on January 19, 2026*

Very good it work good

### ⭐⭐⭐ Tag not writable but bonus cards are
*by A***T on November 2, 2024*

I purchased this product to clone a Schlage 9691T key fob which includes a low frequency RFID for community area and a high frequency NFC MIFARE Classic for room access. 1 out of the 10 tags i received was dead and cant be read at all. I was able to write RFID to these fobs. I was unable to write NFC MIFARE Classic to these fobs, it seems that the UID could not be overwritten. The seller threw in 2 extra cards in addition to the 10 fobs. I was able to write both RFID and NFC to the cards, and confirmed that it worked as expected. Overall, I couldnt get the product to work but the bonus from the seller did allow me to achieve what I needed to do so 3 star for this experience.
