GeoToll’s core technology is based on enhanced GPS (“e-GPS”), which equips smartphones with automatic tolling capabilities on all types of toll roads – express lanes, managed lanes, general purpose lanes, and toll bridges – with over 99% accuracy. GeoToll’s mobile technology can solve the lack of interoperability between divergent tolling protocols that currently exist across state and local toll agencies in the US. The GeoToll front-end hardware is supported by a smartphone app, which is managed by a back‐office system that permits optional outsourcing of customer service and account maintenance from toll agencies to GeoToll.
