The utility model discloses an RFID hand-held terminal for logistics, and specifically relates to the hand-held terminal technology field, the RFID hand-held terminal comprises a terminal main body, the top of the terminal main body is fixedly embedded with a touch display screen and an operation button, the bottom of the terminal main body is provided with a rectangular groove, the rectangular groove is internally hinged with a reader, and the reader is connected with the terminal main body. A handle is rotationally arranged on the side, away from the rectangular groove, of the bottom of the terminal body, the terminal body is sleeved with a protection assembly, and the protection assembly comprises a connecting plate. According to the utility model, the touch display screen and the operation buttons on the terminal main body are protected through the connecting plate and the protective plate, so that the touch display screen and the operation buttons are prevented from being collided and damaged to influence the service life when the terminal main body is held by hand, a reader on the terminal main body is convenient to use by holding the handle, and the reading of label information is realized; after the terminal is used, the logistics worker only needs to rotate the terminal body and move the terminal body into the protection plate again, the structure is simple, and use is very convenient.

This application provides a method and device for reading RFID tags. The method described in this application enables cellular networks to read RFID tags. During the reading process, it ensures compatibility between the cellular network and existing passive RFID tags, achieving a mapping between tag status and RRC status, thereby increasing the compatibility of the cellular network and improving the tag reading distance without modifying existing tag products. Furthermore, the method described in this application can be executed by a relay device, thus avoiding increased computational complexity and power consumption for the tags. It is compatible with passive RFID tags already deployed in business scenarios, ensuring smooth technological evolution.

The application provides a data reading method and a data writing method, and relates to the technical field of data processing. The data reading method comprises the following steps: in response to a data reading command, determining a reading address of image data of a target image, the image data of the target image comprising a pixel block or a pixel row corresponding to the target image; based on the reading address, acquiring the image data of the target image from a storage space; and sending the image data of the target image to a data processing unit. The embodiment of the application supports reading of the image data of the target image of any size, and reduces the occupation of the storage space and the hardware resources.

The present disclosure provides a memory cell, comprising: a stack layer laminated on a substrate, comprising: a plurality of channel holes penetrating through the stack layer and part of the substrate; wherein at least one second laminated material layer in the stack layer after forming the plurality of channel holes is etched to form a ring-shaped limiting structure; a gate dielectric layer located on the surface of the plurality of channel holes after the ring-shaped limiting structure is etched; a channel layer located on the surface of the gate dielectric layer; a resistance variable layer located on the surface of the channel layer corresponding to the ring-shaped limiting structure; wherein the gate voltage applied to the at least one second laminated material layer and the bit line pulse signal connected with the channel layer are controlled to change the resistance state of the resistance variable layer, so as to realize the reading, writing or erasing operation of the memory cell on the resistance variable layer. The present disclosure also provides a preparation method of the memory cell, a three-dimensional memory and an operation method thereof.

This application discloses a retrospective billing method, apparatus, system, electronic device, and storage medium. The method includes: sending application information for first transaction data to a first data source, causing the first data source to send the first transaction data to a second data source; obtaining multiple second transaction data entries for retrospective billing from the transaction data stored in the second data source; billing each of the multiple second transaction data entries separately to obtain a retrospective billing sub-result; and summarizing the various retrospective billing sub-results to obtain a retrospective billing result. This technical solution, in retrospective billing, no longer calculates based on the total amount of historical transaction data, but instead bills each historical transaction data entry separately and then summarizes the results. This ensures that the retrospective billing result comes from each traced historical transaction data entry, providing finer granularity, maintaining consistency with real-time billing standards, and facilitating subsequent reconciliation for trading institutions, thus improving the reconciliation service experience for trading institutions.

The utility model provides a toll station self-made CPC card automatic card reader, and relates to the card reader technology field, the toll station self-made CPC card automatic card reader comprises a vertical block, a frame, a support, a placing platform and a collecting box, the inner side of the frame is rotatably connected with a driven shaft, one side of the frame is fixedly provided with a motor, the output end of the motor is fixedly provided with a driving shaft, and the driving shaft is fixedly provided with a driving shaft. The outer walls of the driving shaft and the driven shaft are sleeved with a conveying belt. According to the utility model, the motor drives the driving shaft, the driven shaft and the conveyor belt to cooperate, and the placement frame, the collection box and other structures work cooperatively, so that continuous and automatic transmission and reading of CPC cards are realized, manual one-by-one operation is not needed, the checking time is greatly shortened, a large amount of labor investment is reduced, and the pressure of shortage of productivity of a grassroots toll station is effectively relieved; meanwhile, due to the adoption of the self-made design, compared with an automatic card reader which is 20,000-100,000 yuan in the market, the automatic card reader has the advantages that the equipment cost is obviously reduced, and the automatic card reader is suitable for batch configuration of a basic toll station.
