I’ll at least leave this here as some form of interim Public Safety Announcement
Always \ use \ a \ test \ card \ BEFORE \ writing \ to \ an \ implant
POPL usage
Generate a URL and write THAT to your implant, this is the safest option and it works.
DO NOT use the write to a POPL card function
it will write a password to your implant, and will take some tools and knowledge to remove it.
