ISO/IEC 15693 is the best choice for NFC if range is a key factor in the application. However, the range depends on the reader used and the size of the antenna connected to the RF430FRL152H. For example, using a TRF7970AEVM and a RF430FRL152HEVM (passively powered) and outputting a constant RF field with the TRF7970AEVM, the range is approximately 9 cm. As mobile handsets generally do not leave the RF field on all the time, there will be observed reductions in read range when interfacing with them. Additionally, if the RF430FRL15xH is used to source power to other devices, the read range is expected to decrease. For further information on RF communication ranges between handsets and RF430FRL152H, see the reading performance section in RF430FRL15xH NFC and ISO/IEC 15693 sensor transponder practical antenna design.
