JASAG Smart Access Control Copier, RFID Reader Writer, 125KHz Duplicator, 13.56MHz Encrypted Card Decoder, NFC Tag Replicator, with Writable Key Fobs, Free Software

It work for some cards, but not most of them.

The device will NOT function if plugged into a USB-C port on your computer using a plain USB-C to USB-C cable. It' just act dead. If your computer only has USB-C connectors, then you *need* to buy a male USB-C to female USB-A converter, and plug the device's USB-A cable end into the converter, then plug the converter into the PC. That works great.

Did not work. Followed the instructions and it did say read successful and write successful when I scanned the new key, but key does not work on any doors in my building. Tried everything multiple times but no luck. Returned.

I bought it to copy my apartment's key fob, but it didn't work. It does wor for other RFID/NFC tags I have. I used my friend's Flipper to read it and discovered it's a HUD, specifically H10301. So this does not read HUD RFID files.

The device reads fast, but the software for encoding different tags consists of 2 programs that have little to no functionality. There are about really good programs written for encoding nfc tags and this is the one device on the market that is not supported by any of them.

This device code reader works very good when using START DECODE. I did one of my fobs and tried using it and it worked no problems. I would say this device code reader Decode reader is a good thing to invest in.

Nice reader but didn't work for what I need to do. I was trying to write Cards for Login system.

How a I supposed to troubleshoot my issues? It hasn't worked for any of the situations that I've needed it for and I do not know how to torubleshoot it.
