## Questions

### What problem does LISNR solve that NFC and QR codes cannot?

LISNR transmits encrypted data over inaudible ultrasonic sound waves, which do not require line-of-sight the way QR codes do or a specialized antenna like NFC. The protocol works through walls, in loud environments, and on devices manufactured as far back as 2011. For automotive applications, it can unlock a vehicle even when the phone is in a pocket or bag, which Bluetooth Low Energy struggles with in the same scenario.

### Who uses LISNR's technology in production?

Visa has publicly piloted LISNR's ultrasonic push-payments protocol for tokenized transactions. Separately, Jaguar Land Rover integrated LISNR into its walk-up vehicle access system. The company also supports live-event ticketing and building access vendors, though end-customer names in those verticals are often client-confidential.

### Does LISNR require consumers to install an app or new hardware?

No custom hardware is required — LISNR's protocol uses the standard speakers and microphones already embedded in smartphones, point-of-sale terminals, and vehicle infotainment systems. The company licenses a software development kit (Radius SDK) that enterprise developers embed into their existing applications to enable ultrasonic authentication.

### Is LISNR a venture-backed company, and who are its notable investors?

Yes, LISNR is venture-backed. Visa invested in the company in 2019. Earlier rounds included participation from Intel Capital and other technology-focused investors. The company has not disclosed total funding figures in recent years, and it operates as an independent entity headquartered in Cincinnati.

### How does LISNR's security model prevent eavesdropping or replay attacks?

LISNR's transmissions are encrypted using standard tokenization frameworks — analogous to what a mobile wallet uses for NFC — but over an ultrasonic carrier. The token is short-lived and single-use, so even if captured, it cannot be replayed. Additionally, because the frequency band is above human hearing and the payload is small, pattern-based interception requires physical proximity and specialized acoustic equipment, which the protocol's time-to-live signature is designed to defeat.
