Firstly, what kind of work badge is it? Is it a card, fob, something similar? Do you know if it’s high frequency or low frequency? Would you be so kind as to provide a photograph of the readers you use at work? Also, please try scanning the badge with the NXP TagInfo app and tell me about the results. If there is a read, it is a HF card.
The implants are generally divided into two major categories: high frequency (HF) and low frequency (LF). HF systems are often used in public transport, NFC, and sometimes access systems. They can generally be read using your phones reader. LF cards are very common in access systems, and need a special device (like an ACRU122U or aProxmark3 Easy or similar) to read/write to them.
There are also generally two common implant form factors: x-series (glass, pill-shaped, 3x20-ish mm cylinder), that are installed via an injector and flex (7mm x 28mm x 0.5 mm) , which are larger, made from polymer and installed either using a 4g piercing needle or a scalpel and dermal elevator, but offer an improved performance.
Unfortunately, there is no single implant that can do everything. You would probably need at least 2 for what you are trying to do - one for the access systems (depending on the ones your work uses, we will have to find that out first) and a payment implant (if you are in the EU, I would recommend checking out Walletmor which is affiliated with DT; in the US, AFAIK the most streightforward is the Purewrist payment conversion)
@Pilgrimsmaster this may be a hector
