Description: The attendance system is basically an embedded one.The microcontroller plays an important role in the system.
The main objective of the system is to uniquely identify and to make attendance for a person. This requires a unique product, which has the capability of distinguishing different person. This is possible by the new emerging technology RFID (Radio Frequency Identification). The main parts of an RFID system are RFID tag (with unique ID number) and RFID reader (for reading the RFID tag). In this system, RFID tag and RFID reader used are operating at 125KHz. The EEPROM used for storing the details has the capability of storing 256 person details at a time. The PC can be used for restoring all the details of attendance made.
This report provides a clear picture of hardware and software used in the system. It also provides an overall view with detailed discussion of the operation of the system. Platform: |

Description: This project aimed to develop a wireless system to detect and allow only the authorized persons. The system was based on Radio Frequency Identification (RFID) technology and consists of a passive RFID tag. The passive micro transponder tag collects power from the 125 KHz magnetic field generated by the base station, gathers information about the Tag ID and sends this information to the base station. The base station receives, decodes and checks the information available in its Database and Manchester code was used to send those information. The system performed as desired with a 10cm diameter antenna attached to the transponder. The Base Station is built by using the Popular 8051 family Microcontroller. It gets the tag ID and if the tag ID is stored in its memory then the microcontroller will allow the person inside.
RFID Reader Module, are also called as interrogators. Platform: |

Description: RFID 读卡演示程序
* 曼切斯特码 380KHz 64 OTC
* 1个数据位1=168us对应两次跳变,在85us应有一个跳变(1/380*32=84us)
* 曼切斯特码 125KHz 64 OTC
* 1个数据位1=168*3us对应两次跳变,在85*3us应有一个跳变(1/380*32*3=252us)-RFID card reader demo program
* Chester code 380KHz 64 OTC
* 1 bits of data corresponding to the 1=168us two jump, in the 85us should be a jump (1/380*32=84us)
* Chester code 125KHz 64 OTC
* 1 bits of data corresponding to the 1=168*3us two jump, in the 85*3us should be a jump (1/380*32*3=252us) Platform: |

Description: 125K RFID读卡模块，包含UART输出，韦根输出，程序中，根据曼彻斯特原理，找到长电平和短电平，根据跳变沿分析出0数据还是1数据。然后寻找消息头，后面的数据进行 行 列奇偶校验，从而分析出卡号。(125K RFID card reader module, including UART output, Wei root output, in the program, according to the principle of Manchester, to find a long level and a short level, according to jump along the analysis of 0 data or 1 data. Then look for the message header, and then the data for row and row parity check, so as to analyze the card number.) Platform: |

Description: Student walk through attendance system :
RFID tag is being captured from a long range 125KHz RFID reader using NodeMCU (an ESP8266 based development board). The captured tag is being uploaded into the database server via WiFi internet connection. Configuration of WiFi SSID, Password and the System ID has made very simple using serial IO. Platform: |
