Riversmerge Handheld 125khz Copier RFID Smart ID Card Duplicator Used for T5577 or EM4305+5pcs T5577 NO.3 Keychains +5 T5577 Cards

I figured all of these readers were the same, but I was wrong apparently! I bought a cheaper one from eBay. It would not read any of the parking pass cards I had, and I was positive they were 125kHz cards. That reader only beeped once when turning it on. This one beeps 3 times when turning it on. Tried exactly the same cards with this reader, and it read every single one of them perfectly. All of the clones work perfectly. You can scan a key fob and make it a card, or vis versa. It did not working on my building pass, which is NFC, as expected (different frequency).The beeps are what matters apparently; the number of beeps must be code for what protocols it actually supports. If yours beeps 3 times when you turn it on, then it should have no trouble copying 125kHz cards, unless they're encrypted.

This product didn't work for us. It beeped to say it read the fob, then beeped to say it wrote on the blank fob, but then the newly written fob didn't work as expected. We could only get it to "beep" for one of the blank fobs provided. All of the other blanks didn't seem to do anything. Maybe the frequency of our fob wasn't right for this device, but regardless couldn't get it to work.

I regretfully share my experience with the Riversmerge Handheld 125kHz Copier RFID Smart ID Card Duplicator, which has left me thoroughly disappointed and compelled to rate it one out of five stars due to its inefficiency and poor performance.**Performance and Reliability:**My expectations for this copier were unfortunately not met. The device consistently failed to duplicate RFID smart ID cards accurately. Despite numerous attempts and adjustments, the copies produced either did not function at all or were unreliable in operation. This unreliability renders the copier ineffective for its intended purpose and a source of frustration.**Build Quality and Design:**In terms of build quality, the copier feels cheaply made and lacks durability. The materials used seem flimsy, and the overall design does not inspire confidence in its longevity. The buttons and controls are not intuitive, complicating the operation further.**User Experience:**Using the copier proved to be a cumbersome and confusing experience. The instructions provided were unclear and did not effectively guide me through the duplication process. Adjusting settings and troubleshooting issues proved futile, as the copier continued to deliver subpar results.**Value for Money:**Considering the investment made in the Riversmerge Handheld 125kHz Copier, the lack of functionality and reliability makes it a poor purchase. It does not fulfill its primary function of duplicating RFID smart ID cards accurately and efficiently, resulting in wasted time and money.**Conclusion:**In conclusion, based on my experience, I cannot recommend the Riversmerge Handheld 125kHz Copier RFID Smart ID Card Duplicator. It falls short of expectations in terms of performance, reliability, and usability. For those seeking a reliable device for duplicating ID cards, I would advise exploring alternative options with proven effectiveness and positive user feedback. This copier does not deliver on its promises and fails to provide the necessary functionality for practical use.

This was so great. It worked perfectly and enabled me to not have to spend hundreds on new fobs from our HOA for my kids to each have a way to get into our pool. I know there are some that say it didn't work. But if you're fob isn't the right frequency it says it won't work on that, AND your fob you are copying to must be blank... and if you hit the wrong button or didn't read the instructions you can do it wrong and it won't work. But for me it worked great. All my fobs that came with it worked. Great product

Where I live we have a common clubhouse as well as the main gate uses key fob to open. I researched the brand and from their web site found out my existing key fob uses 125MHZThis tool was very easy. Put your existing key fob to the "Antenna" area of the tool and press "READ" Then take one of the supplied key fobs, press it to the antenna area and press "Write" Boom done.I also was able to copy my key fob code to the supplied key cards. So now I have key cards also. I know that the code on all these things is my personal code, so not to give out to anyone I don't trust - but it's great having extra fobs.In researching this tool, there are a ton of different security methods key fobs and cards use. This tool is either going to work great or not at all. Yet for under twenty bucks it was well worth it for me. As the cost of one key fob copy is $25 down at my local big box hardware store.
