FIG. 1 schematically shows a brief block diagram of a system 10 for checkout prompting in accordance with an embodiment of the present disclosure. As shown in fig. 1, system 10 includes server 102, network 104, and collection prompting device 100. The checkout prompt apparatus 100 includes a host module 106 and a head module 108. Host module 106 includes antenna element 110, 4G-Cat1 chip 112, and communication interface 114. Head module 108 includes a segment screen 116 and an OLED screen 118.

With respect to the antenna unit 110, it is configured to receive radio frequency signals from the server 102 via the network 104. In one embodiment, the radio frequency signal may include advertisement and offer information. In another embodiment, when the server 102 confirms that the consumer completes the online payment, i.e., that the payment transaction is completed, the radio frequency signal may include information related to the payment transaction, such as the transaction amount.

Regarding the 4G-Cat1 chip 112, it is configured to decode the radio frequency signal received by the antenna unit 110 into a digital signal; executing a pre-programmed computer program to generate communication instructions from the decoded digital signals; and sending the communication instruction to the corresponding functional module through the corresponding interface, wherein the communication instruction comprises at least one of a control instruction and a data transmission instruction. In one embodiment, the control instructions may include, but are not limited to, switch instructions for the respective functional module, reset instructions for the OLED screen 218, and the like.

In the existing collection prompting scheme, a single chip microcomputer is generally used as a main controller, and a 4G-Cat1 chip is used as a data transmission module, so that a high-main-frequency high-performance CPU of the 4G-Cat1 chip is idle. In the embodiment of the present disclosure, the 4G-Cat1 chip 112 not only serves as a data transmission module, but also is connected to the 4G mobile network through the antenna unit 110 to receive data from the server and decode the received radio frequency signal into a digital signal; and also as a main controller, runs a pre-programmed computer program to generate communication instructions based on the decoded digital signals, thereby controlling the operation of the entire collection presentation apparatus 100.

Through the embodiment of the disclosure, the CPU with high main frequency and high performance of the 4G-Cat1 chip is fully utilized, and a single chip microcomputer is omitted, so that the cost is reduced, and the size of the money collection prompting device is reduced.

Regarding the communication interface 114, it is configured to communicate between the host module 106 and the header module 108 to transmit a communication instruction from the 4G-Cat1 chip 112 to the header module 106.

Segment code screen 116 and OLED screen 118 are located on first and second sides, respectively, of header module 108, the first and second sides of header module 108 being opposite.

In one embodiment, segment code screen 116 is oriented toward the merchant and OLED screen 118 is oriented toward the consumer. In one embodiment, when the server 102 confirms that the receipt transaction is complete, the radio frequency signal may include the transaction amount for the receipt transaction. At this point, segment code screen 116 is configured to display the transaction amount to the merchant, for example. The OLED screen 118 is configured to display the transaction amount to the consumer, for example.

In one embodiment, the OLED screen 118 may be further configured to display advertising and coupon information when the checkout transaction is completed. Additionally or alternatively, OLED screen 118 may be further configured to display other information, such as mobile network connection status, network signal strength, battery remaining capacity, and the like.

In one embodiment, the OLED screen 118 may be further configured to display clock time. For example, when the collection prompting device 100 is powered on and connected to a network, the 4G-Cat1 chip 112 determines the time of day over the network pair and generates a clock signal based on the internal clock reference of the 4G-Cat1 chip 112. The 4G-Cat1 chip 112 may be configured to transmit the generated clock signal to the OLED screen through the communication interface 114 to display a clock time on the OLED screen.

In one embodiment, the head module 108 is pluggable with respect to the communication interface 114 of the host module 106. In one embodiment, the head module 108 is reversible with respect to the host module 106. For example, after flipping, segment code screen 116 is located on a second side of head module 108 to face the consumer, and OLED screen 118 is located on a first side of head module 108 to face the merchant.

When OLED screen 118 is facing the consumer, the consumer may be informed of advertisements and offers from OLED screen 118. When the OLED screen 118 faces the merchant, the merchant can know the mobile network connection condition, the network signal strength, the battery remaining capacity, the clock time, and the like from the OLED screen 118, thereby providing convenience to the merchant. Since the segment code screen 116 and the OLED screen 118 can display the transaction amount in real time, the merchant and the consumer can conveniently and timely know the transaction amount no matter how the collection prompting device 100 is placed or whether the head module 108 is turned over relative to the host module 106. For example, when the merchant needs to hang the collection prompting device on a wall surface to save the floor space, the segment code screen 116 may be oriented toward the wall surface and the OLED screen 118 may be oriented outward according to the actual scene, so as to provide more information. Therefore, the embodiment of the disclosure can display the amount of money to be collected in multiple scenes, and can play the advertisement and the preferential information issued by the cloud through the OLED screen when the money collection transaction is not carried out, so that the functions of the money collection prompting device are expanded, and various different requirements of merchants and consumers are met.
