Software emulation of contactless smart card behaviour within a portable contactless reader device

摘要

A handheld transit fare device is provided. The transit fare device includes an NFC interface configured to send and receive data, a memory, and a processor. The processor is configured to receive, via the interface, a list of transactions from a host device using standard smart card protocol commands and reply structures. The list of transactions includes identifiers of fare access media used to gain access to a transit vehicle. The processor is configured to store the list of transactions on the memory and to provide a first indication that the list of transactions has been received. The processor is configured to receive, via the interface, an identifier from a fare access media on the transit vehicle, determine whether the identifier from the fare access media matches one of the identifiers from the list of transactions, and provide a second indication that provides a result of the determination.
