NFC/MIFARE
DynaFamily readers with a contactless interface can exchange commands directly with NFC tags and MIFARE cards through pass-through commands and can present themselves as a card to another reader through NFC card emulation. This guide explains the supported card technologies and how contactless support is organized; the pass-through commands themselves live in the API & Command Reference.
Applies to: DynaFamily readers with a contactless (NFC) interface — DynaFlex II PED, Go, SCR, and DynaProx.
Supported card technologies
The reader provides a pass-through command for each supported tag family, letting your host send commands to, and receive responses from, the card directly:
NTag / MIFARE Ultralight (Type 2)
Pass-through for NTag and MIFARE Ultralight tags.
MIFARE Classic / MINI / Plus SL1 (Type 2)
Pass-through for an activated MIFARE Classic, MINI, or Plus SL1 tag.
MIFARE DESFire (Type 4)
Pass-through for MIFARE DESFire tags.
MIFARE Plus (Type 2)
Pass-through for MIFARE Plus tags.
Each card's unique identifier is returned as the NFC UID data object.
How pass-through works
Once the reader detects and activates a contactless tag, your host sends tag-specific commands through the matching pass-through command above and reads the tag's responses. For lower-level access to any card that supports the ISO 14443-4 APDU, use Generic Pass-through Commands. Entering and leaving pass-through mode is handled by Pass-Through Mode Start/Stop, and Start/Stop Polling requests the reader to poll for a card.
Card emulation (DynaCast)
Beyond reading tags, the reader can emulate a card so it can be read by another NFC device — the basis for MagTek's DynaCast NFC card-emulation use cases. Card emulation is initiated with the Card Emulation command, using the Card Emulation data object.
