Hello,
No it is not possible.
In RFID/NFC, you have basically two types of devices: readers and tags.
The reader is an active device that emits an magnetic field at 13.56MHz and that sends commands over this RF field.
The tag is a passive device that does not emit any magnetic field. It receives the magnetic field from the reader, and use this magnetic field to power itself. It also receives the commands from the reader and answer to them by modulating the magnetic field.
The reader is always initiates the dialog, and the tag only answers to a reader's command.
The tag is not emitting any magnetic field, so tow tags cannot communicate with each others.
Ant7-st25dv04k is a tag. Two tags cannot communicate together. You need a reader on one side (for example a ST25R3911 or a CR95HF) and the ANT7-ST25DV04K on the other side to have communication.
Hope this is helps.
Best regards.
