I don't know if this one is an hardware or software problem but... the life of my credit card reader is 2 months (average).
After this time 4 blue led start blink all together. (one reader seems perfect but the bluetooth doesn't work well)
right now I already changed 4 reader and I have other 4 on my coffee for same reason.
on the last week I tried to make some transaction without any kind of result... everything it seems ok. (bluetooth, connection, screens) but doesn't work.
I tried to change the reader and..... everything works!!!
now the wrong reader works well.... I don't know what was happen
