# pm3py Simulated Transponders — Reference & Comparison

Every transponder model that `pm3py` can simulate, organized by RF frequency and
protocol, with feature-comparison tables. Import any model from `pm3py.sim`:

```python
from pm3py.sim import NTAG216, ST25DV16K, OptigaAuthenticateNBT, SimSession
```

Memory figures are **user memory** (excludes UID/lock/config/OTP pages) per the
manufacturer datasheet. "Faithful" models reproduce the documented command set,
UID prefix, and access rules; a ✓ in a feature column means the model implements
that behaviour (not merely that the silicon has it).

Legend: **T2/T4/T5** = NFC Forum Tag type · **A/B/V** = ISO 14443-A / 14443-B /
15693 (NFC-V) · **DI** = dual interface (RF + wired I²C/SPI) · **EH** = energy
harvesting · **—** = not applicable / not present.

³ **ALM** = Active Load Modulation, unique to the NTAG 5 Boost (NTA5332) among
the NTAG 5 family — a physical RF feature (no command-layer effect; at the APDU
layer Boost is a Link NTP5332 with AES permanently enabled).
