The Near Field Communication Forum is the open platform that has the goal of advancing the use of short-range wireless interaction in consumer electronics, mobile devices, and PCs. The NFC Forum also operates a certification program for analog and digital testing.
The main intention of NFC Forum is to educate the market about NFC technologies and to develop standardized NFC technologies by engineering NFC specifications. They have a liaison with the GSMA to jointly move the NFC technology forward. That's why the GSMA TS.27 NFC Handset Test Book also contains many test cases defined by the NFC Forum.
