Today, I've tried sharing photos using NFC for the first time.

Found it very convenient compared to bluetooth sharing.

I just have a question. I thought NFC has a limited sharing range/distance, meaning that the two devices have to be within a close range of approximately 10 cm. This has been my understanding so far.

Out of curiosity, I tried increasing the distance, and found no problem within 4-5m.
I did turned off wifi and 3g as well. 

How is this possible? Am I missing something here?

Of course, when you pair the devices, they have to be side by side but once it's paired, I found that the devices can be apart 4-5 m and still the files will transfer without any problem.

Can someone explain this to me?

Just to make myself clear, I did photo sharing through NFC, not through wifi direct or bluetooth.
It was between nexus 5 and galaxy s5.

Cheers

I think this actually uses blue tooth to transmit the data. NFC only sets up the connection

When you "bump" the phones together it pairs both the phones by Bluetooth and sends the file via that, on Samsung phones it does it via WiFi Direct.

NFC is used to connect between the phones.

Once connected, the data is transferred by direct wifi or bluetooth (depending on the phone).
