💡 How do people use RFID systems for access control projects? RFID setups give quick and contact free tag reading that fits many control needs. - They work great for locking doors or gates in houses and offices - Low voltage operation keeps power use down in IoT devices - SPI hookups let you add them fast to Arduino or Pi boards - The included cards and tags make testing and rollout simple
