Unlike many other wireless technologies, NFC has a short range of about 1.5 inches. This makes it a good choice for secure transactions, such as contactless credit card payments. MasterCard and Visa are both members of the NFC Forum, and both companies have been involved in pilot programs that use NFC-enabled phones as a flash payment option. Phones could “tap and go” using infrastructure already in place for credit card systems such as MasterCard’s PayPass program or Visa’s payWave.
