If you want, you are free to manufacture the tags yourself.
For that purpose you can find the schematics and hardware designs here. The hardware on this page is licensed under the Creative Commons Attribution-ShareAlike 4.0 International License which specifically allows commercial usage - as long as you mention the origin of our original design openly.
You can choose to use our services for bulk orders and for custom hardware development based on this and other designs we created in the past. Any support for our project is highly appreciated and allows us to continue working on this great project.
