I'm making a web application that takes data from a fingerprint reader. I import all the records to the BD of xampp and up there everything is fine.
When I want to evaluate the assists I find that there are 2 entries.
For example one is: 2018-03-05 08:50:30 and the other 2018-03-05 08:50:52 . This happens when you put your finger on the reader 2 times .. How can I do to delete these records?
