Hi,
basically, a reader or a reader/writter is an NFC device emitting a 13.56 MHz magnetic
field and being able to send commands to a tag and to receive answers from the
tag.
“NFC-A / ISO14443A reader mode�? means that the NFC reader can communicate with ISO14443A tags and is able to send commands to such tags and to receive answers using the appropriate modulation.
Usually, a tag has an internal EEPROM memory, and it usually supports READ and WRITE command over NFC. Reading the tag memory or writing the tag memory is just achieved by commands sent by the user application of the NFC reader.
ST25R95 and other reader devices of the ST25R family are all able to communicate with ISO14443A tag devices. A Firmware library is provided for the various readers of the ST25R family with a complete set of API to communicate with tags.
Be aware that some ISO14443A tags may use proprietary commands and proprietary encryption.
For a simple application, I would recommend using standardized NFC T2T tags such as ST25TN tags which support standard READ and WRITE commands.
Feel free to provide more information regarding your application.
