Frequency devices have become popular for a wide variety of uses. The SyncroZap™ was first made by our company – Self Health Research Center in 1993. We have listened to our customers and added the features you have asked for. 
We however don’t add “bells and whistles” to our zapper in order to pretend to have a better device. We have made good – BETTER. If you purchase our frequency generators you can rest assured that you are buying a sturdy and solid unit made the proper way.
Dr. Clark did not use Zappers with “smart cards” – she did not find it effective. She relied extensively on plate zapping. According to Dr. Clark’s theories, plate zapping is an ideal way to capture and transfer subtle signature frequencies from the item you place on the plates. She explained that the Zapper provides the carrier on which these signature frequencies rides on. For more on the theory of subtle frequencies, see the writings of Dr. Hulda Clark, Ph.D. and Dr. William A. Tiller, Ph.D.*
