I play a lot of arcade rhythm games, mainly Dance Dance Revolution (doubles for life).

A Konami product, login is facilitated through their e-amusement service, which uses an NFC-enabled card. When I first entered the bodyhacking scene, I was immediately enamored by the idea of getting one of mine implanted.

These are migrating to FeliCa/NFC-F (right), but older ISO15/NFC-V cards (left) are still supported. NFC-F being arcane magick, I sought an implantable NFC-V solution.

The DT xSLX is the right spec, but Konami's servers have a UID whitelist—while an xSLX would work on third-party networks, it wouldn’t be guaranteed for official network login. Thus, I needed to find a magic chip...

I made several purchases of pieces to test; Amal was very helpful in describing the issues with each candidate piece I inquired about. Eventually I found this listing (the CoB variant).

CoB has its issues, but proved workable. Amal was able to adapt the chip onto an antenna, and after I confirmed the samples had sufficient performance for my use case, I was able to get one implantable...

Though the spare didn't survive... :(

...two were made, and the other did! One install later... it works!

Of course I got it marked like the rest of my implants (slightly abstract arrows).

I can rewrite it between my two accounts (bar, no-bar~) for e-amusement, but I can also write an AM.Pass to it for Andamiro games too (Pump It Up, mostly).

Big thanks to Amal for all the feedback and work on a less-than-optimal piece of hardware, Satur9 for helping with the antenna, and the DT team as a whole for all their help in making this a reality (and my local friend Cal for donating cards to sacrifice for R&D and testing o7). It's been a year in the making and I'm so excited to have this (one-of-a-kind?) implant.
