I want to make an application on an Android phone for reading an NFC card. A SAM card is required for the authentication process while reading the NFC card.
I'm not aware of any such phone, thought that does not necessarily mean there is none. Typically, Android smartphones are not designed for tasks that require a SAM. You might want to look for Android devices specifically designed for point-of-sale tasks/mobile ordering systems/as merchant terminals.
Android phones usually require the smartcard in the SIM/UICC slot to act as a SIM/UICC card. Otherwise, the card will not be activated and consequently remains inaccessible. A tyical SAM only acts as a key/value store (+ possibly as protocol processor) for a specific target platform and does not have SIM/UICC functionality. Consequently, such a SAM won't be activated in the SIM/UICC slot. However, you might be able to overcome this by
Once your SAM is discoverable as SIM card and once you also added a GlobalPlatform ARA-M applet that grants your application sufficient permissions, you may be able to use either the
icc*() methods of TelephonyManager or, if your device supports it, the Open Mobile API (e.g. provided through SEEK-for-Android) to access applications on the smartcard in the SIM/UICC slot.
