+"""
+This example shows connecting to the PN532 with I2C (requires clock
+stretching support), SPI, or UART. SPI is best, it uses the most pins but
+is the most reliable and universally supported.
+After initialization, try waving various 13.56MHz RFID cards over it!
+Modified and enhanced by F.Javier "habiwan" Puig Diaz in May/June 2025
+Remember to adjust the paths!
+It writes the raw times.csv file which is then used with names.csv later during processing.
+This example is production ready and has been working since June 2025. 
+We were using an excel file that lists the date swiped and name of employee, 
+but now I developed a php webapp with the same functionality and nicer look.
+Copyleft by F.Javier Puig Diaz, July 2026
+UPDATE: mysql for lamp usage (pip3 install mysql-connector-python first of course...)
