What is the difference between an IC and an ID, and which one has higher security?
ID is low-frequency (125KHz) and is cheap. Only has one number and no storage function. It can only be read, written, encrypted, and easily copied.
IC is 13.56MHz, but the price is much expensive. It is readable, writable, and encrypted.
IC cards can be used to write a lot of information such as card numbers, user details, permissions, consumption balances, etc.

and the third block to pay for transportation (subway/bus) and enjoy student discounts.

ID used in access control or parking lot systems or attendance etc.
