Abstract: The invention relates to a smart card, which includes: a card body, having an accommodating recess extending along its own thickness direction of the card body; a decorative part, at least part of the decorative part being embedded in the accommodating recess; in which the decorative part includes a base layer and decorative pieces, more than two decorative pieces are arranged on the base layer, the base layer is connected to the card body, the decorative pieces correspond to the accommodating recess along the thickness direction and are exposed to an external environment. The smart card of the invention can improve the stereoscopic sense, individuation and noble sense of the smart card by arranging the decorative parts with decorative pieces on the card body.

Abstract: Systems and methods for including overstay and human behavior in the pricing structure of a plug-in electric vehicle (PEV) charging station, in order to maximize operating revenue, and manage overstay duration. A mathematical framework with discrete choice models (DCM) is incorporated to operate a PEV charging station with an optimal pricing policy and charge control. The framework determines the probability of a PEV driver selecting various charging options, including overstay price. The pricing options are charging-flexibility, which allows a controller to manage charging costs over a parking duration, charging-asap, which charges the electric vehicle immediately and continuously until the vehicle departs, the battery is fully charged, or a desired level of charge has been reached, and leaving, which is an opportunity cost to the charging station.

Abstract: A station-level framework to operate one or multiple plug-in electric vehicle (PEV) charging stations with optimal pricing policy and charge scheduling, which incorporates human behavior to capture the driver charging decision process. The user is presented with menu of price-differentiated charging services, which differ in per-unit price and the energy delivery schedule. Involving human in the loop dynamics, the operation model results in the alleviation of the overstay issue may occur when a charging session has completed. A multi-block convex transformation is used to reformulate the resulting non-convex problem via the Fenchel-Young Inequality and a Block Coordinate Descent algorithm is applied to solve the overall problem with an efficiency which enables real-time implementation. The pricing control policy realizes benefits in three aspects: (i) net profits gain, (ii) overstay reduction, and (iii) increased quality-of-service.

Abstract: An identification card comprises a card body. A first protective film layer and the first base layer are made of transparent materials; at least a part of a surface of the first base layer is covered by a first graphic layer; a vision effect providing layer has at least one of patterns, colors, textures and gloss which can be visually distinguished. The card body is provided with a first recess portion extending at least through the first protective film layer and the first graphic layer from a surface of the card body and reaching or entering the first recess portion of the first base layer, and thus enabling at least a part of the vision effect providing layer to be seen from the first recess portion. The identification card can improve anti-counterfeiting and personalized customization.

Abstract: A transaction card has a 3D printing graphic surface and a card base. The card base comprises in order from top to bottom: a front protective film layer, a front substrate layer, an intermediate INLAY layer, a back substrate layer, a back printing graphic layer, and a back protective film layer. The upper surface of the front protective film layer is adhered with a 3D printing graphic layer with a height of 0.05-0.46 mm. The transaction card is uniquely designed with a 3D printing graphic effect incorporated in the card surfaces, therefore the overall quality of the card is improved, allowing the transaction card to be widely used in financial, transport, social security, medical care, schools, security service and other fields.
