I agree with @NiamhAstra, The best, yes, BUT not the only way… it really depends on how frequently you will use it.
This is what I would recommend
if it is just a “one off” for a work badge etc.
FREE DOLLAR-EST
I would ask around on this forum to see if there is anybody near you with a Proxmark to help you out.
MOST HIGHLY RECOMMENDED-EST
Buy a Proxmar3 Easy ~$35
BEST TOOL AND MOST EXPENSIVE-EST
Buy a Proxmark3 RDV4 $300 + DT LF Antenna $30
CHEAPEST AND EASIEST-EST
Buy a blue cloner (but this recommendation comes with a clause)
This should do the job, but in the future you may need a Proxmark to “fix” your write.
but really for a little more $, grab a ProxMark3 Easy
