Christina wants to implement access badges printed with picture IDs for her organization, but she wants to use a wireless reader. What access badge technology is commonly implemented in scenarios like this?

RFID badges are the most commonly implemented wireless identification badges. Wi-Fi and Bluetooth both require additional power for devices and thus are not a good fit for a badge, and NFC-enabled badges have not come into common use at this time, although they are increasingly available for mobile device–enabled badges.
