BackgroundNever used RFID before
Lots of material available on lineWanted to learn new concept
Ideas for RFID applicationPet identificationSupply chain managementPassport protectionAccess control
Project SummaryBuild a RFID Control Box
Use a Phidgets RFID reader to detect tagsUse DPDT Relay to activate electronic strike &
deadboltModify control circuit of electronic deadboltUse laptop to control access to the door
Phidgets RFID ReaderReads tags brought
within 3 inches of the reader
Reads any tag with EM4102 protocol
On-Board LEDBoard connects directly
to a computer’s USB portDrivers and source code
for sample application
Output Screen for the Software
Electronic Door StrikeMortise TypeAccepts variable
AC or DC voltagePower Source
16VAC Power Supply
rated at 10VA
Powerbolt 1000 Electronic DeadboltControl box has open
and close switch that made the hack easier
Has an option for standard key in case batteries die
Automatic door locking after 30 seconds
Control CircuitClose & Open

Circuit Diagram
ConclusionsCorrect/updated drivers for RFID readerHave the latest library for RFID reader
before compiling your codeBeyond just opening doorTags need to be compatible / same protocol
before they can be recognized by a specific RFID reader
