Systems, methods, and computer program products for mitigating signal noise at a wireless smart device reader are disclosed. According to one aspect, the subject matter described herein includes a method (performed at a wireless smart device reader) that includes receiving a signal from a wireless smart device and checking for an error in a portion of the signal. In response to detecting the error, an error flag is set in an error register to indicate the presence of noise in the signal portion. The error register is repeatedly polled in order to detect the setting of the error flag. In response to detecting the setting of the error flag, a command to eliminate the signal portion is issued.
