  • Worked beautifully- number of beeps at startup is what matters
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. ... show more

  • Avoid: Riversmerge Handheld 125kHz Copier - Frustrating Experience
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. ... show more

  • This really works!!!!!
I needed an extra key fob & building management was going to charge me $50 which I thought was outrageous. I started to research any cheaper options & found this device on Amazon which is a much cheaper option. Reviews were mixed but I thought if it didn't worked, I'll just return it. But it worked like a charm!!! Took less than 10 seconds to program a fob & I now have extra fobs in case I lose one. Get this if you need extra fobs but don't want to pay the cost you're being charged by others. ... show more

  • Does not work with every electronic key!
Worked very well!

  • It Works !
This item comes with the reader five cards and five fob keys. Within 5 seconds… I press the red button on my key fob and press the write button into the1st key fob. I repeated this process on the remaining key fobs and on four of the five cards. I could not get the last card to copy. In fact, the reader stopped beeping three times. That part made no sense to me because I always put the reader on the original key fob and it beeped three times. I took the batteries in out and put them back in 11 times and each time the reader beeped three times but when I put it on the key fob that I’ve been using all the other times it only beeped twice so…. Long story short it works for everything except for one card. Still worth the price. ... show more

  • VERY EASY and Perfect for my key fobs at my HOA
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 125MHZ This 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. ... show more

  • Even with the right card fob, it didn’t work
The product is cheap enough to make it worth the purchase however, don’t be like me and wait to test it out after the return window closes. It didn’t work for my card and I tried several times. The best I could get was a busy signal light.

  • Worked great on Sureflap cat door tags
My cat lost his collar with the tag on it that unlocks the Sureflap cat door. I put the last spare on a new collar, and needed to get more backups in case he loses another collar. Sureflap tags are $25 for two. A little googling revealed they're 125 kHz, so I thought I'd give this a shot. I read the Sureflap tag and wrote it to one of the keychain tags. Worked perfectly, so I wrote it to the rest, tested them (all worked) and bought a six pack of breakaway collars, so he can lose five more tags if that suits his fancy. I even wrote a card for myself so I can test the batteries. The unit itself is pretty cheap plastic, but I don't care how it looks because it works. ... show more
