In today's world, smartphones are ubiquitous. Gone are the days when phones were synonymous with making calls or sending text messages. Phones are now used for almost anything but that. In more ways than one, our lives have started revolving around them. Phones now contain every confidential and often intimate detail about their owners, from personal chats, to passwords or bank account details. It has thus become imperative to ensure that all this is accessed by only the right person. Despite the obvious necessity, people still loathe to keep a conventional pass code or pattern for their phones because the thought of having to repeatedly enter the same is irritating. The aim of our contribution is to introduce an innovative way to unlock smartphones by using NFC (Near Field Communication) enabled tattoos that are both, highly convenient and secure. We have also provided a working example of an accessory based on the same principle to vouch for its effectiveness in real life usage.
