Systems and methods for personal protective equipment (PPE) verification are disclosed herein. An example method for PPE verification includes capturing, by an image sensor associated with a checkout workstation, one or more images of an individual within a threshold proximity of the checkout workstation; analyzing, by one or more processors, the one or more images to determine whether the individual is wearing personal protective equipment (PPE); and triggering, by the one or more processors, one or more actions based on determining that the individual is not wearing PPE.

A computer-implemented method for cloud-based testing of a payment network may include receiving a test configuration for testing a payment processing network, configuring a simulated worker generator for generating a plurality of simulated workers according to the received test configuration, reading commands to be executed by each simulated worker among the plurality of simulated workers from a command bank according to the received test configuration, configuring the plurality of simulated workers according to the commands and the received test configuration, starting a swarm test of the payment processing network by the plurality of simulated workers, reading results of the swarm test from the plurality of simulated workers, and saving the results to storage.

Methods for accurate object tracking are disclosed herein. An example the method includes receiving, from a first optical imaging assembly having a first field of view (FOV), a first image captured over the first FOV and based on a decode of an indicia associated with an object of interest, identifying the object of interest within the first image. The method further includes determining a location of the object of interest within the first image and mapping the location of the object of interest within the first image to a predicted location of the object of interest within a second image, the second image being received from a second optical imaging assembly having a second FOV and the second image being captured over the second FOV.

Methods and systems to detect items left in merchandise carriers are disclosed. A disclosed example system includes: an input device configured to receive an indication that a merchandise carrier is to be empty from at least one of a user or a device communicatively coupled to the input device; an overhead imaging device configured to capture an image of the merchandise carrier at a checkout station in response to the indication; an image processor configured to detect based on the image an obscuration of a portion of the merchandise carrier by the presence of an item in the merchandise carrier, and generate an alert signal when the portion of the merchandise carrier is obscured; and an output device configured to receive the alert signal and provide a notification of the presence of the item in the merchandise carrier.

A method for determining authenticity of a point of sale device includes: storing a blockchain and point of sale identifier pair, wherein the blockchain is comprised of a plurality of blocks, each comprised of a block header and transaction data values, each transaction data value corresponding to a payment transaction involving a point of sale device associated with the point of sale identifier and includes an indication of approval or denial for the payment transaction; receiving a fraud probability request, the request including the point of sale identifier; identifying a number of transaction data values that include an indication of denial; determine an authenticity value indicating a likelihood that the point of sale device is engaged in fraudulent activity based on a registered latitude and longitude of the point of sale device, the number of transaction data values, and additional criteria; and transmitting the determined authenticity value.

Systems and techniques are provided that allow for efficient and simple provision of reprint indicia, refund requests and refunds for erroneous or damaged indicia, and combinations thereof, without the technical and administrative overhead common to conventional postage systems.

Embodiments of the present invention provide a skip-scanning identification method and apparatus, a self-service cash register terminal and system. The method includes: obtaining a video of a user scanning an item; determining posture data of the user based on the obtained video; determining, according to the posture data of the user, a time period in which a scanning action of the user takes place; receiving a scanning result of the item; and determining whether the user has skipped scanning the item based on the scanning result and the time period.

A sales data processing apparatus includes a display, a product scanner to obtain a commodity code from a product being registered in a sales transaction, a storage unit to store journal data including product information for registered. A controller is configured to record product information for products registered in the sales transaction and output a notification of an error in the sales transaction when detected. The notification is output to the display screen and includes information regarding resolution of the error. The controller executes a first countermeasure for resolving the error, then stops the sales transaction if the error is not resolved. The controller then executes a second countermeasure after the sales transaction has been stopped and starts a new transaction if the error is resolved by the second countermeasure.

According to one or more embodiments, a sales data processing apparatus comprises a processor that registers merchandise which is a sales target and generates transaction registration information having commodity information of the registered merchandise and transaction event information. The processor further detects a failure in the sales data processing apparatus and determines whether the transaction registration information can be transmitted via a network. The processor outputs a code symbol corresponding to the transaction registration information if the transaction registration information cannot be transmitted via the network after the failure has been detected.

Methods and apparatus to indicate off-platter weigh conditions are disclosed herein. An example barcode reading and weighing apparatus includes: a weigh platter having a surface extending in a first transverse plane; a scale configured to measure a weight of an item on the surface; an off-platter detection assembly configured to detect whether a portion of the item is not resting on the weigh platter; a communication interface configured to communicate with a POS system; a processor in communication with the weigh platter, the off-platter detection assembly and the communication interface; and a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the barcode reading and weighing apparatus to, when the portion of the item is not resting on the weigh platter, modify the weight to form a modified weight and send the modified weight to the POS system via the communication interface, wherein the weight is modified to indicate the portion of the item a3 was not resting on the weigh platter.
