A self-service bulk liquor retail terminal built on a stainless steel liquor jar, delivering a closed loop of QR-code purchase, self-service tasting, remote supervision and real-time profit sharing. Remote authorisation allows refilling without opening the jar, keeping the liquor traceable to the factory, while payment is settled and shared instantly. Shown as an OEM sample for the Shejiantai brand; jar bodies can be customised.
