Re: unknown Multifunction Ring / one Tag

use the `lf t55xx` commands,  you need to read up on them,  and you should be able to program it,  with  ´lf em 410x_write´

Re: unknown Multifunction Ring / one Tag

try wiping it and then detect,   but you are on a pm3 easy clone,  I dunno if you have a low Q antenna which is needed to program t55x7
