The Alliance aims to transform the public transportation experience globally by offering a fast and reliable offline ticket verification solution.

Silence Laboratories, a leader in decentralized security and cyber-proof technology solutions is excited to announce its partnership with Chalo, India’s premier public transportation technology platform.

The goal is to offer a fast and reliable offline solution for the verification of bus tickets booked through Chalo’s mobile app using advanced authentication libraries, making the boarding experience of public transportation users contactless, fast, and more efficient.

The verification of the ticket happens, using Silence Laboratories’s SDK- SilentAuth, through two-way communication between the passenger’s phone and the POS terminal held by the conductor/installed in the bus using radio frequency. All of this happens within 1 second leading to a seamless and secure offline solution for passengers and bus operators.

It creates an NFC-like experience and works across NFC and non-NFC devices.

The technology ‘Silent Auth’ is predicted to be the successor of QR code and OTP-based methods that are:

1. Slow (QR code-based verifications took 7 seconds on average due to human errors, variability in light conditions, etc) and

2. Increasingly vulnerable to scams.

With the rise of sophisticated hacking techniques, traditional authentication methods are becoming less secure, leaving businesses and individuals at risk of data breaches and cyber threats. Silent Auth is a next-generation technology that provides a highly secure and efficient way of authenticating passengers offline with proof-of-proximity and full duplex communication.

This collaboration also addresses the region’s low penetration of NFC-enabled phones, noisy environment, and heterogeneous smartphone hardware.

Additionally, it also aids bus operators in managing their fleets more effectively. With a streamlined ticketing process, operators can optimize routes, monitor ridership, and plan schedules more accurately.

“In our quest to digitize mobility and especially ticketing, partnership with Silence Laboratories has been crucial in delivering a seamless, reliable, and blazing fast in bus transaction experience. Using Silent Auth in an offline, secure, and P2P mode, we have been able to offer an under 1 second tap-to-pay experience to the masses of India. “ said Vinayak Bhavnani, Co-Founder & CTO at Chalo,

Chalo has launched the first phase of deployments for any commonly available smartphone, to tap on the conductor’s POS terminal and validate a ticket bought on the app — simply tap and board!

Vinayak highlighted that ”on-ground ticket validation through QR code took 7 seconds on average, owing to multiple points of interactions through applications on both the conductor and passenger sides. Silent Auth transformed this. Faster, offline, and usable verification are very important to create an NFC-like experience, particularly in Indian and South Asian geographies where bus stops are very crowded”

As pioneers in their respective fields, both Silence Laboratories and Chalo share the common goal of making a lasting impact on the transportation industry and setting a new standard for public transportation in South Asia and globally. This partnership is just the beginning, and both companies are excited to explore further opportunities for innovation.
