Abstract: A system and method are provided for electronically verifying age-restricted purchases using biometric data and digital communication. The method comprises: receiving an application from a website via an electronic device; creating a customer account linked to the customer; and gathering biometric information—such as facial structures and thumbprints—using the customer's communication device. An approved customer receives a token. During a purchase, the customer scans an age-restricted product, and the store device prompts for self-age verification. The customer's biometric data is used to access the web application in purchase mode. The store device provides a transaction token barcode/QR code, scanned by the customer, which combines with the customer token to form a request token. This request token is sent to a centralized server for processing. Upon approval, an approval token is received by the store device, authorizing the age-restricted purchase.

Abstract: A greenhouse having a hollow framework structure (20) with water under pressure fluidly disposed inside characterizing a combined structural frame and water pipe. A number of spray nozzles (34) are attached to the framework at appropriate locations and drippers (60) are, likewise, attached. The nozzles atomize the water increasing the humidity inside the greenhouse and the drippers water the plants beneath. A transparent enclosure consisting of walls (42) and a roof (44) envelope the framework and are attached with straps (50). Air ciculation is achieved by windows (52) and vents (54) along with an optional fan (56).
Abstract translation: 具有中空框架结构（20）的温室，其中具有流体地设置在内部的压力的水，其特征在于组合的结构框架和水管。 许多喷嘴（34）在适当的位置附接到框架，并且同样附着滴液（60）。 喷嘴雾化水，增加温室内的湿度，滴水器将植物下水。 由墙壁（42）和屋顶（44）组成的透明外壳包围框架并与带（50）连接。 通过窗口（52）和通风口（54）以及可选的风扇（56）实现空气净化。
