The invention relates to a method for training a machine learning model to identify a subject having at least one machine readable identifier providing a subject ID, said method comprising: providing a computer vision system with an image capturing system comprising at least one image capturing device, and a reader system comprising at least one reader for reading said at least one machine readable identifier; defining said machine learning model in said computer vision system; capturing a first image using said image capturing system, said first image showing said subject; reading said subject ID using said reader system when capturing said first image, and linking said subject ID with said first image, said linking providing said first image with a linked subject ID, providing a first annotated image; capturing at least one further image showing said subject, linking said linked subject ID to said at least one further image providing at least one further annotated image, and subjecting said first annotated image and said at least one further annotated image to said machine learning model for training said machine learning model.

Some embodiments include a smart card reader system that includes a card reader cavity that is impervious to liquid. The card reader cavity includes a secure card reader (SCR) holder bonded to a printed circuit board (PCB), to provide a liquid barrier between the SCR holder and the PCB. The PCB includes an SCR spring contact connector. The card reader cavity can receive a smart card including an integrated circuit (IC), where the IC is coupled to the SCR spring contact connector. A processor coupled to the SCR spring contact connector, can receive an input regarding a transaction using data of the smart card, and execute the transaction. In some embodiments a roller system seals the card reader cavity when the smart card reader system is not in use.

A connector includes a casing and a contact pin. The casing includes a storage portion. A connection body is mounted in the storage portion by being relatively displaced in a first direction. The contact pin is held by the casing. The contact pin includes an elastic contact part. The elastic contact part includes a first protrusion and a second protrusion. The first protrusion protrudes toward the storage portion. The second protrusion is separated from the first protrusion. The second protrusion faces a direction crossing the storage portion. The second protrusion protrudes in a direction crossing the first direction.

A method for interrogating an electronic identity card by a terminal with a claim covering an identity attribute of the holder of this card. The terminal obtains an identity token of the CNIe then selects in a HD wallet an issuer account associated to the identity attribute covered by the claim. Afterwards, it forms a transaction including as arguments the identity token and the path in the arborescence of the wallet leading to the issuer account, this transaction then being transmitted to a blockchain. Afterwards, it is verified by consensus that the terminal is habilitated to issue a claim covering an identity attribute, and that the issuing address of the transaction corresponds to the identity attribute on which the terminal is habilitated to issue a claim.

Various embodiments provide a dual purpose press-bar and heat sink for an integrated circuit card (ICC) reader. The dual purpose press-bar and heat sink provides two functions. First, the dual purpose press-bar and heat sink conducts and dissipates internal heat generated by a high data transfer ICC inserted in to the ICC reader. Second, the dual purpose press-bar and heat sink ensures that contact pads of the high data transfer ICC create reliable electrical connections with ICC contacts of the ICC reader. As such, the dual purpose press-bar and heat sink simultaneously dissipates heat from a high data transfer ICC and ensures that a high data transfer ICC maintains proper electrical connections with ICC contacts of an ICC reader.

The invention relates to a method for training a machine learning model to identify a subject having at least one machine readable identifier providing a subject ID, said method comprising: providing a computer vision system with an image capturing system comprising at least one image capturing device, and a reader system comprising at least one reader for reading said at least one machine readable identifier; defining said machine learning model in said computer vision system; capturing a first image using said image capturing system, said first image showing said subject; reading said subject ID using said reader system when capturing said first image, and linking said subject ID with said first image, said linking providing said first image with a linked subject ID, providing a first annotated image; capturing at least one further image showing said subject, linking said linked subject ID to said at least one further image providing at least one further annotated image, and subjecting said first annotated image and said at least one further annotated image to said machine learning model for training said machine learning model.

In a card connector, a main body has a plugging space formed therein and used to locate terminals of a terminal set, two sliding members of a sliding mechanism are movably disposed on two sides of the terminal set in the plugging space, respectively, and each sliding member has a supporting part protruded on a side thereof and extended into the plugging space, and elastic members are abutted between sides of the two sliding members and two opposite sidewalls of the plugging space, respectively; a terminal of a guiding rod is slid along a guiding groove, and other terminal of the guiding rod is inserted through the main body; a push plate of a shielding housing is abutted with the guiding rod, so that a preset electronic card can be stably inserted into or ejected out of the plugging space through the two sliding member.

A connector tray inserted into a connector body in an insertion direction while accommodating an object to be connected includes a tray body configured to accommodate the object to be connected, a tray exterior portion connected to the tray body to be displaceable along the insertion direction, and a push-push mechanism disposed between the tray body and the tray exterior portion in a tandem arrangement and configured to displace the tray exterior portion in the insertion direction between a first position away from the tray body and a second position close to the tray body.

A bankruptcy board game, including a game board, including a plurality of spaces disposed on a perimeter of the game board, and a plurality of card retaining areas to receive cards thereupon, a spinner unit removably disposed on at least a portion of the game board to control a course of action of at least one player during a game, and a plurality of figurines to move around the plurality of spaces and represent a position of the at least one player on the game board.

A method and apparatus for processing a commerce transaction performed with a terminal reader for reading a card are disclosed. In one embodiment, the method includes receiving transaction information for a merchant regarding a transaction involving the terminal reader without the terminal reader having an assigned terminal identifier (TID) that is used for transaction authorization and assigning the terminal reader a pre-allocated TID for the merchant as the assigned TID, where the pre-allocated TID is selected from a group of one or more pre-allocated available terminal IDs (TIDs) associated with the merchant, and using that pre-allocated TID to obtain authorization for the transaction.
