The xNT was the first NFC implant, sporting an NTAG216 for NDEF shenanigans. It also works with some access control systems–check out the compatibility matrix for details.
The xSIID is an NTAGI2C with 1k of usable storage for NDEF and an LED. The color on sale is white.
The Apex Flex and flexSecure are smartcard implants. There is a collection of apps available which are mostly focused on digital security (such as FIDO2, OTP, HMAC-SHA1, etc). The Apex Flex is locked in the Fidesmo Ecosystem which makes app deployment a breeze but loses some storage space because of it. The flexSecure relies on command lines tools such as Global Platform Pro for handling installation and removal, however, we are now preloading our most popular apps to make it easier to use. The flexSecure has roughly twice the store capacity of an Apex.
Edit:
We are including a free J3R180 with the first 10 flexSecure sales during the Cyborg Monday sale : )
I was thinking of getting an xmagic and a next. Im on my phone now, but i thought there was also a bundle with those two plus another. Was just hoping that one or both of those would also be on sale, hence my question
Unfortunately, it doesn’t look like it’s on sale, but but just so you know the other implant spark2 basically works out to be a free implant for the cost of the other two.
Whilst it might not be in the sale per se, You’re still winning.
