i need your help.
I was charging or tried to charge the reader but after some minutes the red light went off, I guess it is for showing if it is being charged or not, so I guessed it was not charging at all.
This morning the reader said low battery and was not working.
I plugged in, red light went off after 5 minutes and now it says it is fully charged.
So I am afraid it is not charged at all, it just shows so.
What can be the problem and how can I solve it ?
Thanks in advance.
