ETEKJOY 10 PCS Writable 125kHz RFID Blank Card Proximity ID Card Key Token Tag Rewritable T5577 Universal

rewritable cards are great if you are not tracking individual cards. otherwise the read only cards have to be programmed into your system one at a time. usually taking upwards of 5 minutes each

Works great for hid 125khz.

The media could not be loaded.  This is by far the worst and most irritating product I have ever purchased since all of the cards were not working as they should of, only a couple of them were working out of the 10 of them that I purchased. This is video proof that one of them it did not work and I am absolutely disgusted and it was such a waste of time for me to go back and drive and return it. Completely misleading and there is basically zero quality control so if you’re looking forward to getting a product that might not work and might result in a return that this is the product for you. I do not recommend getting this and finding another product.

I was looking for writable NFC tags or cards and these came up in a search and were well-reviewed. However, they do not use NFC. They use RFID and cannot be written using NFC technology. I'm not sure if the search terms were set by the merchant or by Amazon. If, like me, you are looking for NFC cards, these are NOT the product for you. :)

If you have an RFID cabinet drawer lock and are looking to make additional keys, consider buying these cards instead - 125KHZ EM4100 Read Only RFID cards -https://www.amazon.com/gp/product/B01M1L7NHI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1.

I sent these back as they were not what I needed.

Got as described
