IC card reader and operating method thereof
An IC card reader may comprise a first interface unit that communicates with an IC chip of an IC card by using a first communication mode, a second interface unit that communicates with the IC chip by using a second communication mode, and a control unit that controls the first and second interface units, and reads data from the IC chip through an interface unit, which first receives a response message from the IC chip, between the first and second interface units.
1. An IC card reader comprising:
a first interface unit configured to communicate with an IC chip of an IC card by using a first communication mode;
a second interface unit configured to communicate with the IC chip by using a second communication mode; and
a control unit configured to control the first and second interface units such that the first and second interface units simultaneously communicate with the IC chip, and read data from the IC chip through an interface unit, which first receives a response message from the IC chip, between the first and second interface units.
2. The IC card reader according to claim 1 , wherein the first communication mode is a mode of communicating with the IC chip while contacting with the IC chip and the second communication mode is a contactless communication mode.
3. The IC card reader according to claim 2 , wherein, when failure occurs in a process of reading the data through the first interface unit, the control unit reads the data by using the second interface unit.
4. The IC card reader according to claim 3 , wherein, when failure occurs in the process of communicating with the IC chip through the first interface unit and the second interface unit, the control unit determines whether a specific signal is normally detected through at least one contact pin of the first interface unit.
5. The IC card reader according to claim 4 , wherein, when the specific signal is normally detected, the control unit allows the at least one contact pin to contact with the IC chip again.
6. The IC card reader according to claim 4 , wherein, when the specific signal is not normally detected, the control unit sets a contact point of the IC card again.
7. An operating method of an IC card reader, comprising the steps of:
attempting communication with an IC chip of an IC card by using a first communication mode;
attempting communication with the IC chip by using a second communication mode simultaneous with the step of attempting the communication with the IC chip by using the first communication mode;
receiving at least one of a first response message based on communication using the first communication mode and a second response message based on communication using the second communication mode from the IC chip; and
reading data from the IC chip by using a communication mode of the first communication mode and the second communication mode, which corresponds to a response message that is first received between the first response message and the second response message.
8. The operating method of an IC card reader according to claim 7 , wherein, in the step of receiving the at least one of the first response message based on the communication using the first communication mode and the second response message based on the communication using the second communication mode from the IC chip, when the first response message is not received, it is determined whether the second response message is received.
9. The operating method of an IC card reader according to claim 8 , further comprising the step of:
releasing a contact between a first interface unit and the IC chip when the second response message is received.
10. The operating method of an IC card reader according to claim 9 , further comprising the step of:
determining whether a specific signal is normally detected when the second response message is not received.
11. The operating method of an IC card reader according to claim 10 , further comprising the step of:
re-attempting a contact between the first interface unit and the IC chip when the specific signal is normally detected.
12. The operating method of an IC card reader according to claim 10 , further comprising the step of:
re-adjusting a contact point between the first interface unit and the IC chip when the specific signal is not normally detected.
13. The operating method of an IC card reader according to claim 9 , wherein the specific signal comprises a power signal.
14. The operating method of an IC card reader according to claim 7 , wherein the first communication mode is a mode of communicating with the IC chip while contacting with the IC chip and the second communication mode is a contactless communication mode.
15. An IC card reader comprising:
a first interface unit configured to communicate with an IC chip of an IC card by using a first communication mode;
a second interface unit configured to communicate with the IC chip by using a second communication mode; and
a control unit configured to control the first and second interface units to communicate with the IC chip simultaneously, read data from the IC chip through the second interface unit when failure occurs in the first interface unit, and read data from the IC chip through the first interface unit when failure occurs in the second interface unit.
