NFC support in Android varies depending on the terminal manufacturer/model.Because of the fact that "Osaifu -Keitai" has been supported since the age of featurephones, many Android devices made in domestic manufacturers are still equipped with FeliCa chips and can be electronically settled.

Many Android terminals that support Osaifu -Keitai support also support NFC Typea/B.In fact, FeliCa/NFC -related features used in the iPhone, such as the balance inquiry of the electronic money card and the reading and writing of the NFC tag, can be used for most Android devices sold via a major communication carrier.
