Yes yes yes yes give it at least 5 days more like a week before you expect any kind of reproducible results. The swelling from getting stabbed with a big needle really makes it hard to read.
Have you guys tried to read your chip with your Samsung? I did mine today and I don’t know if I should be worried or if it’s normal. Haven’t tried it on a terminal yet except before doing the surgery to make sure it was working.
Thanks
