Using the TRF7970A EVM With PC GUI
2.6 FeliCa Tab
This tab is used to poll for FeliCa transponders. This transponder technology is from the Sony Corporation
and is primarily used for payment, and it is also included in the NFC Forum specification, just like ISO/IEC
15693 and ISO/IEC 14443 transponders.
2.6.1 Polling
When inside the FeliCa tab, first select the radio button to select the protocol and click Set Protocol, then
click Execute to retrieve the Manufacturer ID and the Manufacturer Parameters from the tag (see
Figure 26). The Polling radio button is automatically selected.
Figure 26. FeliCa Polling Example
2.7 Find Tags Tab
The Find Tags tab is a GUI-controlled version of the standalone mode that the reader defaults to when
powered up but before the TRF7970A EVM GUI is executed. When this tab is selected, all of the
supported protocols are selected to be polled for. Deselect any of the protocols that are not desired and
click Run, which then turns into a Stop button (see Figure 27 and Figure 28). While this tab is useful for
showing the multiprotocol capabilities of the TRF7970A EVM, it must be understood that the EVM antenna
is a certain size and generates a specific magnetic field and also that the transponders are resonant
circuits and can couple with each other, so some appropriate separation between the devices is
recommended. The ISO15693 and ISO14443B transponders are polled for with multiple slot commands,
while the FeliCa and ISO14443A transponders are polled for with single slot style commands only.
