Apple has actively been working on making iPhone the sole thing people have to carry while out and about. The company has successfully eliminated the need to carry items such as diary, laptop, car insurance card, credit card, home keys, etc. They also recently announced plans to help humanity get rid of the need for car keys. However, in the USA iPhones have not yet been able to be used as an official I.D. such as a passport or a driver’s license.
Adding an airline ticket to your iPhone wallet has been possible for years, but travelers still have to carry a physical form of identification when traveling overseas. Many have said that if iPhones can read your passport, they will also be able to replace it, but the company has been struggling with this task as passports and I.D. cards are still a requirement for international travel.
