Have you ever thought about the proximity features available in some applications that allow, for example, using a phone as a loyalty card? Have you ever seen NFC tags available in various forms, such as stickers? If so, you can ask yourself a quite simple question: Can I use them to perform some operations in an automatic way, just after touching such a tag with a smartphone? The answer is really simple: yes. What is more, the development of such a feature is convenient due to the availability of a set of classes, as you will see in this recipe.
As an example, you will create an application that allows opening a website after reading an NFC tag by touching it with a phone. Of course, the website address will be stored in the NFC tag. Thus, you can create a collection of favorite websites as stickers and open websites directly in your application, just by touching tags!
