Welcome
If you’re looking for suggestions I would recommend the proxmark3 easy. DT sells them pre flashed with iceman firmware here:
This lets you get the full set of tools for rfid and is only slightly more than that blue cloner.
A free suggestion is to get the TagWriter and TagInfo apps by NXP. NXP manufactures rfid cards and the chips for implants. I suggest you could use your phone and TagInfo to scan your current cards. If you get a result that means they’re high frequency cards and the type will tell you what implant options you may have. If they don’t scan it is likely low frequency and that proxmark would tell you what it is and is the tool to clone it. This way you have the correct expectations before you buy the implants.
There’s a post about sharing the scan from these apps here: How to share NFC chip data via TagInfo app
