Introduction

Near field communication (NFC) is a form of contactless communication between devices or between a device and a chip/tag. Using NFC, a user can transfer/receive small amount information from a short distance (example, 10 cm).

Card-emulation mode, as the name suggests, makes the device behave like a contactless smart card. Using this mode we can develop virtual credit cards, debit cards, transit cards, and access cards. In this tip document, sample code from a Web app is shown for understanding.
