Campus IC card

    The main function of this campus IC card is to distribute it to students for commuting to and from school. Nowadays, many schools require students to wear campus IC cards for safety reasons. Additionally, they help prevent outsiders from entering or leaving the campus. Therefore, campus IC cards play a very important role. So, what are the detailed parameters of campus IC cards?

The main parameters of campus IC cards are:

1: Capacity is 1025 bytes EEPROM
2: Divided into 16 sectors, each sector contains 4 blocks, each block contains 16 bytes, with blocks as the unit of access.
3: Each sector has its own set of passwords and access controls.
4: Each card has a unique serial number, which is 32 bits.
5: Features anti-conflict mechanisms and supports multi-card operations.
6: No power supply, built-in antenna, includes encrypted control logic and communication logic circuits.
7: Data retention period is 10 years, allowing for 100,000 rewrites and unlimited reads
8: Operating temperature is -20°C~50°C (humidity 90%)
9: Operating frequency is 13.56MHz
10: Communication rate is 106KBPS
11: Read/write distance within 10cm (related to the reader/writer)

    Therefore, based on the above parameters, we can see that campus IC cards are very secure—not only secure but also reliable. The security lies in that campus IC cards cannot be imitated or hacked. The reliability lies in the standardized international parameter indicators, ensuring long service life, fast sensing speed, increased efficiency, and reduced personnel expenses.
