# Class NfcF

java.lang.Object
com.codename1.nfc.TagTechnology
com.codename1.nfc.NfcF

public class NfcF extends TagTechnology

FeliCa (JIS X 6319-4) technology view -- the contactless protocol used by Suica, PASMO, ICOCA and other Japanese transit / payment cards.

On iOS the app must declare its target system codes in the plist `com.apple.developer.nfc.readersession.felica.systemcodes` and ship the matching NFC entitlement -- the Codename One Maven plugin and build daemon do this automatically when they see `Nfc` / `NfcF` in the classpath.
