First Claim
Patent Images
1. A near field communication (NFC) payment object reader comprising:
- a power subsystem including a power source;
an NFC subsystem including an antenna; and
a tuning subsystem that tunes the antenna, the tuning subsystem receiving information from the power subsystem, wherein based on the information from the power subsystem, the tuning subsystem initiates;
a first tuning process while the information from the power subsystem indicates that a power level of the power source is below a predetermined power level threshold; and
a second tuning process while the information from the power subsystem indicates that the power level of the power source exceeds the predetermined power level threshold.
