What is the difference between IC card and ID card?
- IC cards is usually 13.56MHz, while ID cards is lower, usually 125kHz. So, IC cards and ID cards cannot be used on the same card reader unless the reader supports dual frequency.
- IC card has the ability to read, write, and encrypt, while the ID card only contains a fixed card number and does not have storage function.
- The general ID card coil is circular, while the IC card coil is rectangular. Like as below，
What kind application you can consider using 125 KHz RFID cards?
Compared to HF and UHF RFID cards, the cost of 125Khz ID cards is lower. Therefore, in some scenarios that require low-cost, such as small access control systems, attendance systems, etc., using 125Khz ID cards is an economical choice. The reading distance of the 125Khz ID card is relatively far, usually within the range of 8-15cm, which makes it very useful and quickly identification in scenarios that require long-distance recognition. For example parking lot management systems.
But pls notice 125Khz ID cards usually need reading only, so their security is relatively lower but can meet basic needs such as community access control systems, library borrowing systems, etc.
