In some implementations, a printing system may include a card printer that includes a printing controller and a marking device. The card printer may be configured to receive a first printing instruction or a second printing instruction associated with printing an account identifier on a card. The card printer may receive one of the first printing instruction or the second printing instruction based on whether a risk score, associated with the account identifier, satisfies a threshold. The card printer may print a full account identifier, associated with the card, on a surface of the card based on receiving the first printing instruction. The card printer may print the card without the full account identifier on the surface of the card based on receiving the second printing instruction.

Systems and methods to perform validation of authentication of a security device in a decentralized network are disclosed. In one aspect, embodiments of the present disclosure include a method which can be implemented on a system to, identify telemetry associated with the successful authentication. The telemetry is further in a distributed ledger in the decentralized network and can be used to determine validity of an authentication attempt of the security device by a second user device.

Security devices having chaosmetric artifacts from fractal patterns are disclosed. In one aspect, embodiments of the present disclosure include a security device, having a physical surface having formed thereon a composite pattern. The composite pattern can created from created from joining of an imprint of a first base pattern and an imprint of a second base pattern. The first base pattern can be created from a first basic building block. In one embodiment, the first base pattern is a fractal pattern based on the first basic building block which forms chaosmetric artifacts in the physical surface upon printing.

A transaction card having a discontinuous metal stratum with a desired degree of electrical eddy current disruption disposed on a surface of a first layer, such as a glass or other transparent layer. A transaction module disposed in the first layer is electrically isolated from the discontinuous metal stratum. The discontinuous metal stratum may include a plurality of isolated metal features that form a halftone pattern, such as a pattern that is visibly opaque to the naked eye.

The invention provides a card substrate for carrying a chip module, the card substrate has a first surface and a second surface opposite to the first surface, and a concave portion for accommodating the chip module, the concave portion includes a first concave portion, and a second concave portion further recessed from a bottom wall of the first concave portion, in a left-right direction, a size of the second concave portion gradually narrows from a middle to both sides, and in an up-down direction, the size of the second concave portion gradually narrows from the middle to both sides. The card substrate of the invention can provide good support and protect for the chip module.

A method for producing a document structure, wherein the method includes producing a chip structure by forming a cavity in a carrier having a top side and an under side, picking up a chip having at least one chip contact and a redistribution layer (RDL) connected to the at least one chip contact by means of a picking-up device detaching the chip from an auxiliary carrier, wherein the chip bears on the auxiliary carrier by way of the RDL, wherein the chip is lifted up from the auxiliary carrier by means of pressure being exerted on the RDL, wherein the lifted-up chip is picked up and inserted into the cavity, and wherein the RDL is oriented on the top side of the carrier, fixing the chip in the cavity by means of an adhesive, electrically conductively connecting the at least one chip contact of the RDL to an electrically conductive region of the carrier by means of an electrically conductive material, and embedding the carrier between a first paper layer and a second paper layer.
