American Green has introduced a vending system that enables the vending of controlled or age-restricted products using biometric verification, according to a press release.

The biometric verification portion of the system is used by the U.S. military and large corporations that require high levels of security for identification prior to entering a facility. In addition, the system can be accessed via an app that allows remote purchasing.

Upon arrival at the machine, patrons log into their account, verify with the biometric control, and simply display the QR code on their smartphone to retrieve the product or products they purchased.

"American Green and our technology partner, PanPacific, have been working non-stop to improve this process for over four years now," David Gwyther, chairman and acting president at American Green, said in the press release. "The adoption of smartphones, familiarity with apps on those phones, and improvement in related vending technologies have now merged with a concept that the public could easily grasp before but are much more prepared to use now."

"Creating a process that allows flexibility in the machine selected by clients yet permitting verified accounts to log in to the machines of any companies who choose to participate will grow adoption faster and simplify use by all parties," he said.

"A baseball fan could buy a beer at the game in New York and cannabis from a dispensary in California the next day through the same app utilizing their verified account," he said. "This is a huge step forward for smart retail and the automated sale of regulated products."
