collections

Lessons Learned - FacilitiesYou need to be very aware of interference and the

proximity of metal (including nails/screws in furniture, drawer rails, cable and wiring management…) with any of the readers/antennas.

RFID readers/antennas create a reading zone that is symmetrical below and above the antenna. Putting metal below the antennas shrinks the size of the reading cloud both below and above the antenna.

• Laws of physics apply no matter what a vendor promises

• Weak signal may read a chip BUT need stronger signal to write to the chip and turn off security bit
