Abstract: A transfer request is received from a terminal, in which the transfer request carries a user identity (ID) of a first user, a user ID of a second user, and a virtual card ID of the first user; the virtual card is transferred from user account of first user to user account of second user, based on the user ID of the first user, the user ID of the second user and the virtual card ID; an image for transferring the virtual card is obtained; an image library of the virtual card is obtained; an image ID and the image are stored into the image library of the virtual card.

Abstract: A marking composition may include an aqueous carrier and thermochromic capsules. The thermochromic capsules may include a leuco dye, an activator, and a temperature regulator. The thermochromic capsules may have a volume average size effective to resist temperature-mediated discoloration at a temperature of at least up to 40° C. by dissipating heat. In some embodiments, the marking composition marks a substrate with a substantially erasable mark, for example, in response to frictional contact with an eraser.

Abstract: Ink formulations and associated writing instruments are disclosed herein. In some embodiments, an ink formulation is provided which includes an ink resin or polymer and a biobased solvent. In some embodiments, an ink formulation is provided which includes an ink resin or polymer and a solvent comprising at least one lactate ester.

Abstract: A lifting table includes a lifting mechanism, a base, an upper tabletop and a tabletop mounting frame assembly; the lifting mechanism includes a plurality sections of lifting columns and a controller, and the lifting columns are matched and connected with one another; the base is installed at a bottom of the lifting mechanism, the controller is hidden in the base and connected with buttons on the tabletop mounting frame assembly; the upper tabletop and the tabletop mounting frame assembly are both installed on lifting columns, and the tabletop mounting frame assembly is located below the upper tabletop; through selection of buttons on the tabletop mounting frame assembly, a signal is sent to the controller so that the controller drives the lifting columns to stretch out or draw back and hence to drive the upper tabletop and the tabletop mounting frame assembly to raise up or lower down.

Abstract: The disclosure provides transitorially erasable ink compositions, including an aliphatic hydrocarbon solvent, a rubber dissolved in the aliphatic hydrocarbon solvent, a hydrophilic pigment, and a surfactant. The disclosure further provides methods of preparing transitorially erasable ink compositions and writing instruments comprising transitorially erasable ink compositions. The disclosed erasable ink compositions write well, have strong color and erase easily transitorially, and demonstrate color stability.

Abstract: The application discloses stable correction fluids and/or correction fluids that change from colored to substantially white (or to a color substantially matching the color of a substrate to which the correction fluid is to be applied) after application to a substrate.

Abstract: The application discloses ink compositions containing an emulsion and, more particularly, to ink compositions containing an emulsified colorant and/or an emulsified lubricating agent, and writing instruments containing same.

Abstract: An improved color changing correction fluid is provided which includes either a volatile base or a volatile acid in combination with a color changing pH indicator, all in a water based fluid or system. As the fluid dries, the volatile base or acid evaporates along with the water and the pH color changing indicator changes from a colored state to a clear state. For white paper, a white pigment is utilized and therefore the fluid changes from a colored state to a white finished state as the solvent water and acid or base evaporates. Different color pigments can be utilized to match the color of the particular paper or substrate.
