RFID Card by Nialabs

RFID cards that power attendance, access control & cashless systems.

What is an RFID card?

An RFID ( Radio Frequency Identification) card is a contactless smart card embedded with a microchip and an antenna. The embedded microchip stores data and supports encryption. The RFID card communicates with reader devices and performs functions such as access control, identity verification, cashless payments, inventory management, etc.

Unlike barcodes, RFID cards do not need to be seen to be read. They can be read through wallets, pockets, or purses.

Antenna
