Story

Background

Since commute in the Delhi Metro is far from comfortable, we wanted to create a new kind of wristband and mobile app via latest IoT technologies that comfort the journey of passengers, thus making great use of up-to-technology to create smarter, efficient and scalable solution and replacing existing technology.

MetroBand

MetroBand does the work of metro cards, tokens, and notifies you at important events. The band knows where the passenger has to get down or change stations and hence, the band vibrates on the wrist to alert the passenger through haptic feedback. It also has a unique identity attached to it and can act as a metro token or card. In the case of a metro card it follows the concept of having a prepaid account linked to the band. MetroBand is also a mobile app that allows you to recharge MetroBands prepaid accounts and track metrics such as number of passengers in the coach and times when the coaches are usually empty or filled up. All of this happens on the fly by the power of Internet of Things.

Components

The MetroBand consists of a microcontroller, an RFID Antenna, an RF antenna, an OLED Display and a Lithium-Ion battery.

How it works

Information about the next metro station is sent to the MetroBand through beacons installed in metro coaches. As the set destination approaches, the band will vibrate to inform/wake the commuter. In addition, relevant details will be displayed on the OLED display. Apart from this, an app is also created to track important metrics and to recharge metro payment accounts.
