Near-field communication (NFC) is on the leading edge of wireless technology, allowing consumers to assimilate and apply their loyalty programs, credit cards, gifts cards and coupons all on one mobile device. Because of the recent advance in online banking, shopping, and other activities, we have become largely dependent on our mobiles. It is not a surprise that the idea of providing a convenient and simple all-in-one wallet, keys, and phone would become an appealing concept. However, this might seem like a big jump for many older generations, as the fear and skepticism of credit cards and online banking when they were first introduced don’t seem too far off. There are many consumers concerned with security regarding stolen phones, as well as privacy issues. Consumers are expecting stringent security technology and policies on bank transactions. The fact that buyers are not the only ones who must use this new technology presents another obstacle to face. All businesses must also eventually offer NFC usage, which can be difficult to implement in a short period of time. Although the concept is very attractive, it appears that the implementation and fortifying of near-field communication will take a considerable period of time.

Here is an example of NFC in use for various parking usages:
