Low Frequency vs High Frequency
Low frequency readers are often cheaper (although not always due to the mass production of high frequency).
High frequency tags can often have a shorter range than low frequency.
High frequency tags are often cheaper due to mass production volumes.
125kHz RFID Reader Design – Electronic Product Design
RFID Circuit & PCB Design Notes
It's usually very important that the voltage supply to an RFID reader is protected from ripple and interference.
Where you have noisy electronics in the proximity:
A simple RC filter of 10R and 1000uF will go a long way to preventing interference. Better still is using a separate power supply from a dedicated voltage regulator if you have the option.
