Is NFC power consuming?

From the documentation of a typical NFC-IC (NXP MFRC522) can be learned that NFC chips consume approximately 40 mA while reading or writing NFC tags (active mode). However, scanning the environment requires much less energy than establishing a NFC connection. During sleep mode NFC chips only consume between 3 and 5 mA.
