Method for downloading applications into smart card

Abstract

The embodiment of the invention provides a method for downloading applications into a smart card. The method comprises the following steps: intelligent equipment receives a trigger signal for downloading an application program; the intelligent equipment acquires key information of the smart card from a vehicle-mounted unit via a communication link between the intelligent equipment and the vehicle-mounted unit, wherein the smart card is in contact-type connection with the vehicle-mounted unit; the intelligent equipment sends an application program downloading request to an application program providing platform, wherein the application program downloading request comprises an application program mark of the application program to be downloaded and the key information of the smart card; the intelligent equipment receives data of the application program from the application program providing platform; and the intelligent equipment downloads the data of the application program into the smart card via the vehicle-mounted unit. According to the embodiment of the invention, the application program can be downloaded under the premise of not increasing the cost and the power consumption of the smart card.

Description

technical field [0001] The invention belongs to the technical field of smart cards, in particular to a method for downloading applications into smart cards. Background technique [0002] Traditional contactless smart cards (i.e. IC cards with chips inside, including but not limited to bank cards, gift cards, employee cards, etc.) Smartphones communicate, based on the short communication distance of NFC and the limitation of long-term stable connection, traditional smart cards cannot transmit large data packets between card readers or smartphones. However, with the popularization of smart phones and the widening of the functions of application software, people are more and more inclined to use their smart phones to do what they want to do anytime and anywhere. It is hoped that the business such as recharging in the electronic wallet of the smart card can be completed through the smart phone held by oneself, which requires the establishment of a relatively long-term stable co...

Problems solved by technology

[0003] In the face of meeting the above requirements, NFC communication cannot be satisfied due to its poor stability and the weakness of the small amount of transmitted data. Therefore, a solution has emerged to connect the smartphone and the smart card through Bluetooth to achieve stable transmission of more data. , but this needs to add a Bluetooth module to the smart card. This method not only requires the user to replace the existing smart card without a Bluetooth module, but also the power consumption of the Bluetooth module will cause an excessive burden on the battery with a small capacity in the smart card. , requiring the user to recharge frequently
