ＮＦＣカード通信における動的電力レベル

Title:

ＮＦＣカード通信における動的電力レベル

Document Type and Number:

Japanese Patent JP7286814

Kind Code:

B2

Abstract:

Various embodiments are directed to dynamically and temporarily adjusting power to an NFC reader of a computing device from a first power level to a second power level based on a feedback mechanism between a contactless card and the computing device. The contactless card may provide a message containing a checksum. The computing device may receive the message and calculate a checksum based on the received message. By comparing these two checksums, it may be determined whether the entire message has been correctly received. If not, the power to the NFC reader may be temporarily increased to allow better communication between the contactless card and the computing device.
