Information processing terminal, data selection processing method, and program
First Claim
1. An information processing terminal that has a plurality of data communication portions that receive data from a read/write unit by a non-contact method, comprising:
- a data processing portion that selects and processes one of the data received by a first data communication portion that is one of the plurality of data communication portions and the data received by a second data communication portion that is one of the plurality of data communication portions; and
a load modulation portion that performs a load modulation with respect to a response to the read/write unit according to the data processing in the data processing portion.

Abstract
There is provided an information processing terminal that has a plurality of data communication portions that receive data from a read/write unit by a non-contact method. The information processing terminal includes a data processing portion that selects and processes one of the data received by a first data communication portion that is one of the plurality of data communication portions and the data received by a second data communication portion that is one of the plurality of data communication portions. The information processing terminal also includes a load modulation portion that performs a load modulation with respect to a response to the read/write unit according to the data processing in the data processing portion.

11. A data selection processing method that selectively processes data that is received by a plurality of data communication portions that are provided in an information processing terminal, comprising the steps of:
-
detecting a synchronization code in a first data that is received by a first data communication portion that is one of the plurality of data communication portions; detecting a synchronization code in a second data that is received by a second data communication portion that is one of the plurality of data communication portions; selecting from the first data and the second data the data in which the synchronization code was detected first; performing a cyclic redundancy check for the selected data; and processing the selected data if the result of the cyclic redundancy check has no errors.

-
detecting a synchronization code in a first data that is received by a first data communication portion that is one of the plurality of data communication portions; performing a cyclic redundancy check for the first data; detecting a synchronization code in a second data that is received by a first data communication portion that is one of the plurality of data communication portions; performing a cyclic redundancy check for the second data; selecting from the first data and the second data the data for which the cyclic redundancy check was completed first without any errors; and processing the selected data.

13. A computer program that is used in an information processing terminal that has a plurality of data communication portions that receive data from a read/write unit by a non-contact method, the computer program comprising instructions that direct a computer to function as:
-
a first data communication section that controls receiving of data by a first data communication portion that is one of the plurality of data communication portions; a second data communication section that controls receiving of data by a second data communication portion that is one of the plurality of data communication portions; a data processing section that selects and processes one of the data received by the first data communication portion and the data received by the second data communication portion; and a load modulation section that performs a load modulation with respect to a response to the read/write unit according to the data processing in the data processing section.
