Systems and methods for controlling access to wireless gaming devices and networks are provided. For example, access is controlled through one or more levels of security checks, such as a hard security check instead of or in addition to a soft security check. In a hard security check, the user employs an apparatus such as a card or other physical token that can be used to access the wireless gaming device. Such an apparatus may communicate information that identifies the user to the device or may simply be used to produce a signal without which the device is locked to users.

Aspects described herein may allow for a payment card having enhanced edge patterns. The payment card may include a complex edge morphology on the physical card that may make the payment card more likely to be used by consumers and makes the payment card stand out due to the enhanced edge design. The edge of the payment card may be reeded, crenelated, or may include various shapes of various sizes on one or more of the edge walls extending around the payment card. The edge of the payment card may also include dimples, chips, and/or other complex design patterns cut into the face of the payment card close to the edge. The payment card may also include inclusions of other materials, such as metals, ceramic, and/or polymer to be added which fill or partially fill any voids produced by the edge patterns.

Techniques for characterizing an optical system (for example, a printer verifier) are provided. In this regard, the optical system may be characterized for scanning a printed image. The characterization of the optical system includes determining an effective aperture size of the optical system, and correspondingly an effective resolution at which the optical system can be configured to scan a portion of the printed image according to verification requirements.

A printing system and method print different colors onto a target object to form a machine-readable data representation having a symbol contrast of at least 40%. The printing system and method direct print heads to print the different colors by printing a base layer of a first color of the different colors on the target object and printing an upper layer of a different, second color of the different colors on top of the base layer of the first color, or by printing print the machine-readable data representation as an interdigitated data representation by printing the different colors onto the target object so that none of the different colors is printed on top of another color of the different colors.

A system and methods for zero-step customer proximity detection using mobile device low emissions beacons, which uses a customer mobile device, a single or plurality of BLUETOOTH™ low-emissions (BTLE) beacons, a network, a server, and an application that may operate separately on a mobile device and the single or plurality of BLUETOOTH™ low-emissions (BTLE) beacons, which allows businesses to detect known customers that come within a specified proximity of any connected BTLE beacons, and provide interactions with them on a zero-step and socially distanced basis, track their proximity to other customers and staff using similar applications, manage table assignments, offer deals or provide incentives to enter or patronize a business establishment.

A mobile passport, mobile passport generation system for generating same, and mobile passport certification method enable increased convenience for certifying passports. The passport is generated by digitalizing passport information written in an actual passport, thereby eliminating the risk of losing the passport, and with which the certification of a passport for a foreign tourist is carried out by scanning or inputting the digitalized passport information. A mobile passport, which includes a QR code including passport information, a photo writing unit, a country writing unit, and a manual certification number, is generated by using a mobile passport generation system which includes a mobile passport generation unit, a password generation unit, a mobile passport management server, and a terminal. The identity of a passport holder can be checked by checking the QR code, the manual certification number, a coupon number, and a tax return transaction number associated with the generated mobile passport.

Systems and methods for controlling an automated electronic networked central clearinghouse for clearing and reversing reversible exchanges of digital assets are disclosed. Exemplary implementations may: execute an instance of a game; receive an exchange request that indicates a first user offers a first digital asset for a reversible exchange on a fiat-currency-based online exchange platform; access a decentralized database to obtain asset-specific distribution rights for the first digital asset; generate publication information of the first digital asset for publication on the online exchange platform; receive exchange information regarding the reversible exchange; temporarily transferring the ownership of the first digital asset; determine whether to reverse the reversible exchange, and either (i) transfer the ownership of the first digital asset to the first user, or (ii) clear the reversible exchange by non-temporarily transferring the ownership to the exchanging user, and by distributing benefits in accordance with the asset-specific distribution rights.

An information processing system includes an information bearing medium and an information reading unit. The information bearing medium has a two-dimensional array of unit data zones. Marks are provided on some of the unit data zones so as to form a digital code. Mark patterns of any two Y-directional adjacent unit data zone strings based on the arrangement of marks in an X-direction differ from each other. The information reading unit generates a data string on the basis of a unit signal formed from a plurality of signals output from a group of detection units that detect the marks in synchronization and recognizes the digital code of the information bearing medium on the basis of a group of the data strings sequentially obtained from the array of the unit data zones.
