 MFRC522-python
 ==============
-
 A small class to interface with the NFC reader Module MFRC522 on the Raspberry Pi.
-
 This is a Python port of the example code for the NFC module MF522-AN.
 
 **Important notice:** This library has not being actively updated in almost four years.
 It might not work as intended on more recent Raspberry Pi devices. You might want to 
 take a look to the open pull-requests and forks to see other implementations and bug-fixes.
