Galaxy S4 mini GT-i9195 comes with nfc and there are multiple apps to read e-passports (like nfc passport reader). The nfc antenna is part of the battery.
Trying to read two passports only one could be read successfully. Connection to the second passport got interrupted. Trying to change the position of the mobile did not help. Removing the cover of the mobile did not help either.
The nfc antenna is glued to the back of the battery. In case one has two batteries it is possible to modify one battery. Li-Ion batteries may burn, so only continue if you know what you are doing.
The outer protection foil has to be removed. Then the nfc antenna can be carefully peeled off from the battery. Just keep the two connections to the battery connected. Finally the nfc antenna can be glued with tape to some plastic card as shown on the attached photography. - The bottom of the battery has to be insulated with tape. Plastic card and battery have to be connected with tape to protect the two thin antenna connectors.
Result: second passport could be read. Probably because the antenna coil is no longer disturbed by the metal of the battery underneath.
