Need to identify a RFID card, and allow access to a controlled space? Maybe log the time and date when a user swipes their card?
Now you can with an inexpensive (<$10) RFID solution. Just supply a Arduino, and maybe a relay to control a door strike, or a real time clock module to log date and time with the card number and user name.
We connected our RFID Module as follows:
RFID Arduino
SDA 10
SCK 13
MOSI 11
MISO 12
IRQ N/C
Gnd Gnd
RST 9
3.3v 3.3v

We also connected the anode of a Red LED to pin 6 and the anode of a Green LED to Pin 5. Cathodes of each connect to a 330 ohm resistor and then to Gnd. Look in void loop() for the interesting bits.
Where code

I dont find a N/C port on my Arduino uno, what yo do?
N/C means "no connection"
I tried to upload the code but I had an error. error: espcomm_upload_mem failed
Sounds like you are using a esp8266, not an arduino. Make sure you have the correct board and upload speed selected.
Hey, May I ask you an Question? How to connect database(Microsoft Access) with arduino UNO?
Use VBA to connect access to the arduino. VBA has a serial object that is ideal for this.
Hey could that reader detect my contactless bank card?
I doubt it, but check here for more details – https://en.wikipedia.org/wiki/Contactless_smart_card
