101 are no longer good only 201, 101 is for real cards aka Dumps that have no chip, 201 are the new upgraded cards aka dumps with the chips that the system upgraded too that may be your problem with 101 dumps
I got these off eBay supposably they Are able too tap too pay but they don’t have a mag strip on the back just chip but the chip is bigger then regular chips are these good or I should just toss out
