Step 4: At the same time, OLED will show "0", meaning no one is queuing. Then, take NFC label to swipe through the sensor area and the receiver will show 1, meaning people start to queue up and there is a first customer to take care. At the same time, no matter how many time you swipe through, the display on OLED remains the same, meaning the queuing people are increasing. At the receiving end, as long as you press the next button, the displayed number on OLED will add one and you will hear "Next", meaning the former customer has done with his/her business. Result You can simulate a Bank Queuing System. Video
