Embodiment Construction

[0034] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0035] Since the POS machine payment needs to be associated with the banking system, especially in offline transactions, it cannot be connected with the acquiring host. Before the transaction, it is necessary to obtain the card number information provided by the bank to report the loss. When the transaction is made, it is first necessary to confirm The transaction card number is not the card number for reporting the loss, otherwise the transaction cannot be carried out, so as to ensure the security of the transaction.

[0036] see Figure 1 to Figure 2 , the present invention sets the sorted area and the extended area in the POS machine. Wherein, the method for the POS machine to store the lost card number includes the following steps:

Abstract

The invention provides a method for positioning the number of the reported lost card rapidly on a POS machine, which comprises the following steps: storing the sequenced information of the reported lost card in a sequenced area, and storing the non-sequenced information of the reported lost card in an extended area; inquiring the sequenced area during transaction, wherein if the information of the reported lost card is found, it means that the number of the reported lost card is reported and the transaction is refused; and inquiring the extended area if the information of the reported lost card is not found, wherein if the reported lost card is not found, it means that the number of the reported lost card is legal. By inquiring by adopting the dichotomy, the inquiring speed is increased, the requirement for the hardware is low, and the transaction time of the client is shortened under the condition of limited software and hardware. In addition, by storing in different areas, not all the storage areas need to be inquired, the writing and erasing frequency of the storage areas is reduced, and the service life of the hardware in the storage areas is prolonged.

Description

technical field [0001] The invention relates to an information positioning method in the POS field, in particular to a method for quickly locating a lost card number on a POS machine. Background technique [0002] With the diversification of POS machine applications and the convenience of using POS machines for transactions, POS machines are also gradually being used in offline transactions (such as: the purchase of train tickets, refueling at gas stations, and even credit card consumption in cafeterias). There are more and more types and quantities of cards, and the resulting problem is that the number of lost cards is also increasing. In order to ensure the safety of property, these lost cards should be prohibited from continuing to consume or trade after reporting the loss. [0003] At present, many POS use to directly store these lost card numbers in RAM or non-volatile storage media. When a transaction occurs, the transaction card numbers are sequentially traversed to d...
