LIGC Application was an Israel-based producer of Laser-Induced Graphene filters (LIG). LIGC Application is at the forefront of laser-induced graphene commercialization with patented technology. In 2013, laser-induced graphene was first derived from a plastic substrate by Professor James Tour of Rice University, and LIGC has based its work on this technology.
The company went out of business in 2022.
UK-based start-up Payper Technologies is using graphene to provide the restaurant industry with a new pay-at-table technology.
Graphene antennas are printed on paper to enable customers to pay their bill by tapping their smartphone on the receipt. The process was said to take two clicks and under five seconds, without the need to download an app, by using existing Apple Pay or Google Pay.
