Not in the flex form factor. There was a FlexMT, but it shows as discontinued in the store. Here is a post that explains why those and other chips are no longer sold
I think the only dual HF/LF chip currently available is the NExT v2, which is an x-series bioglass implant that has a T5577, NTAG, and LED all in one.
I’ve been using the original xEM and xNT bioglass capsules for 5+ years now and haven’t had much issue with range for access control. Sometimes I have to put my hand at a weird angle, but I can get reliable reads most of the door locks and HID readers I’ve come across.
I’ve been holding out for a reliable flex implant that has LF/HF/LED in one, but given the number of issues over the years, I’m going to go with the NExT 2 for my next implant.
