Finally an iOS compatible app that actually reads a US passport. It’s tricky when you scan the RFID chip since you have to position the top of the phone exactly around the center of the passport’s back cover. Also, make sure the passport booklet is open, otherwise the cover’s material will block the signal. It’s a security feature built into the passport. I do hope my data can be downloaded into a text file, instead of view only. Also, I tried on two genuine passports. One was issued about 4 years ago, and it shows data authentic and country signer as “SUCCEEDED found a chain to a trust anchor”. The other passport was issued about 3 months ago, and it shows as authenticity not validated, due to the country signer as FAILED. I know for a fact both passports are real, why is the new passport won’t pass authenticity check? Is it because the passport is too new, and the RSA encryption is different? I’m not aware of a security update to US passports in the past 4 years. Can someone explain? Thanks!
