Smart Cards, which includes information on both contact smart cards and contactless smart cards, as well as 125Khz low-frequency, 13.56Mhz high-frequency, 860-960Mhz ultra-high-frequency, and dual-frequency smart cards.

A smart card is a secure device that can store and process information. Contact smart cards, also known as chip cards, require physical contact with a reader in order to communicate. Contactless smart cards, on the other hand, use radio frequency technology to communicate with a reader without the need for physical contact.

Low-frequency (LF) smart cards operate at frequencies between 30 KHz and 300 KHz, and are commonly used in access control systems, public transportation, and other applications that require short distance communication. High-frequency (HF) smart cards operate at frequencies between 3 MHz and 30 MHz, and are commonly used in applications such as payment systems, identification systems, and electronic passports. Ultra-high-frequency (UHF) smart cards operate at frequencies between 300 MHz and 3 GHz, and are used in applications such as logistics and asset tracking.

Dual-frequency smart cards, as the name suggests, operate at both high and low frequencies, and are used in applications where both long and short distance communication is required.
