Here we present our current collection of pre-programmed chip cards. Our targeted frequency therapy with these special chip cards arose from requests made by our therapists and users, in order to provide quickly accessible therapies. Our database continues to expand as requests come in. Our chip cards work on the devices BW21 Goldenstream (from version V12B), BW2020, BW2021, VM, as well as the therapist device BW77. When ordering, please always let us know whether you need a VM, BW or DL chip, depending on your device. Further information regarding the correct assignment of chip cards and the corresponding frequency devices can be found in the FAQ.
