1. Application Scenario
For government and enterprise customers, employees carry RFID cards and automatically identify their identities when they pass the attendance recognition point, and automatically check attendance. Compared with the traditional short-distance credit card attendance system, the RFID long-distance attendance method can realize batch staff attendance and avoid the crowding of credit card during working hours.
2. Technical selection analysis
RFID long-distance personnel attendance usually has 3 RFID technologies to choose from, 900M UHF passive RFID, 2.45G single-frequency active RFID and 2.45G/125K dual-frequency active RFID technology, 900M UHF passive has also been carried out by many integrators Try, the effect of the attempt is not ideal. The three RFID technologies applied to the attendance scenarios of government and enterprise remote personnel are as follows:

Suitable application scenarios |
|
900M UHF RFID |
l Cheap card cost l No battery, no maintenance |
l Wearing on the human body, the recognition effect is not ideal, the card needs to be taken out to shake, and the reading rate is not high when it is placed in the chest or pocket. l High equipment cost |
l Suitable forThe door is narrower,at the same timePass bynumberfew. |

3. Application scheme
3.1. System structure
3.2. Application process
Deploy RFID calibration readers at the time and attendance recognition points. The main personnel carry RFID identification cards (in their bags or pockets), and automatically recognize them when they approach the recognition range of the RFID calibration readers. The calibration readers will communicate the identified card numbers The gateway or access control controller is transmitted to the backstage of the business system for automatic attendance management.

4.4. Time Attendance System Platform
The attendance system is based on the B/S architecture. The system functions are divided into nine major functions: equipment management, shift management, shift management, holiday management, leave management, overtime management, business trip management, compensation management, and data reporting, each of which has a major function It is divided into several sub-functions.
4.4.1. Device Management
Device type management
Function: Manage attendance equipment, including adding attendance equipment, modifying attendance equipment, and deleting attendance equipment
Basic information management
Function: Summarize the distribution map of all attendance equipment, which can be managed
Function: Manage the whitelist in the attendance machine, which belongs to the whitelist in the attendance machine, and has the attendance function. Including whitelist production and whitelist cancellation.
4.4.2. Shift management
Function: the shifts of management staff in different time periods. Including shift time management and personnel shift management.
Shift time management
4.4.3. Shift management
Function: Set the working time of the attendance machine. It can be scheduled weekly or monthly.
4.4.4. Holiday management
Function: manage attendance on holidays
4.4.5. Leave management
Manage employees’ leave.Including leave type management and leave management
4.4.6. Overtime management
Function: manage overtime types and overtime data
4.4.7. Business trip management
Function: To manage the type of business trip and data.
4.4.8. Replenishment management
