I want to do this: mobile app <-> NFC <-> microcontroller, in order the MCU can communicate with Android or iOS apps via NFC hardware.
I have two options of low-cost NFC chips, these chips don't support the same standards. Supported standards are:
- ISO 14443, using NFC chip M24SR04
or
- ISO 15693 and ISO 18000-3, using NFC chip M24LR04E
Which of theses standards is most used in modern smartphones? Or both are supported on most mobiles? I want to make a choose regarding the NFC chip based on that information.
Actually I want to make it via NFC and I don't want any type of RFID, I want to communicate the MCU with the apps via NFC.
This is on Wikipedia:
ISO/IEC 14443 Identification cards -- Contactless integrated circuit cards -- Proximity cards is an international standard that defines proximity cards used for identification, and the transmission protocols for communicating with it.
ISO/IEC 15693, is an ISO standard for vicinity cards, i.e. cards which can be read from a greater distance as compared with proximity cards. Such cards can normally be read out by a reader without being powered themselves, as the reader will supply the necessary power to the card over the air (wireless).
ISO/IEC 18000-3 is an international standard for passive RFID item level identification and describes the parameters for air interface communications at 13.56 MHz.
