if you wanna write this to a T5577 (much cheaper) you can write an em4100 credential, these are often cross compatible so long as the system hasn’t disabled em4100 (most don’t turn it off because they don’t know it’s a security flaw)
your clone command is: lf em 410x --id 0002D5F3D6
@tac0s has enlisted me for the wiki when it goes up and i’ve got some time off work i’ll make sure things like this are documented step by step with correct syntax so there’s no confusion in the future.
