I used these to clone a Schlage 9691T fob, which in my case uses 125 kHz RFID for gates and building entry, and 13.6 MHz NFC for the Schlage BE467F unit entry door lock. It worked fine (both protocols) using a Flipper Zero. Cloning the 125 kHz RFID portion was trivially easy. Cloning the 13.6 MHz NFC portion using the Flipper Zero required some work and time, and probably shouldn't be attempted by those that don't have experience or understanding of these protocols UNLESS they are willing to take the time to research and follow instructions to the letter. But after getting past the hurdles, it worked great. I'm very happy with these cards.

you can almost copy any type of card as long as you have the right device to decode and encode and within the frequency range of the card including shearable cards

The LF chip does not show up until you write to it. After a couple of attempts, I managed to clone a HID tag successfully. Likewise the HF chip took a couple of attempts and re-positioning of the card on the Proxmox, but did successfully write as a magic gen1a card. So far the card has not had any problems on the target readers.

Proxmark3 detects a T55x7 (consistent with a T5577) and a Mifare Classic or Plus (either are 1k+). I've cloned cards to both chips successfully and they work exactly as they should. These two chips in one card gets you the ability to clone just about anything to these as needed and can be used independently (one credential on each chip for two different credentials on the same card).They're a tiny bit thicker than a credit card (.037" versus a credit card's .032"), but thinner than HID cards that I've carried in the past. They're plenty flexible and ride nicely in a wallet. There's enough space around the antennas (visible with a bright light source) that you could punch out a lanyard hole if you were careful.I'd recommend these for anyone looking for an all-in-one card!

This has a Gen1A magic chip and LF chip. A great work.

The low frequency T5577 element in this credential works as advertised. It comes pre-programmed as an EM41xx style credential but is not password locked and can easily be wiped, rewritten, etc.Unfortunately, we were not able to get the High Frequency "Magic" MIFARE S50 credential to work properly with ANY of our equipment. We tried multiple Proxmark tools, third party tools, etc. The cards will sometimes read but their antennas are very problematic. It is not possible to perform sustained read/write functions on the MIFARE chip without getting errors, no matter where we put the card in relation to the antenna.(Our Proxmark devices are all running the very latest RRG code base and are flashed with the latest firmware.)

Ordered 5 and they all worked on both frequencies. I then ordered another 60. Very satisfied with this find.

I used the Flipper to clone a HID Prox to the LF portion and a MIFARE Classic 1k S50 to the HF portion. Test reads confirmed the results. Two cards in one, you can’t beat it.
