October 2015 may have been a deadline for many businesses to start accepting chip-based cards, but the months since then have shown a slow adoption rate. However, as the use of these cards grows in the coming years, there may be more of an incentive for owners to update their point of sale credit card processing systems to match. For businesses, it could be important to remember that the EMV deployment is a work in progress, with possible changes on the horizon.

Looking at a broader view of conversion, businesses can expect more purchasers to use cards with chips in them, according to an article from CreditCards.com. This piece predicts that all but 4 percent of EMV debit cards will be "in consumers' hands" within two years, building on the progress from financial groups in this and the next year.

Timing also plays a role in the recent Payment Card Industry Security Standards Council decisions regarding guidance updates. In a recent interview posted on the PCI blog, Troy Leach, the Council's Chief Technology Office, said that the latest version of the Data Security Standard is now slated for a March or April release. Previously, the update was planned for far later in the year.

"We are sensitive to the drastic changes that are happening with payment acceptance – from advancements in mobile payments to EMV chip rollout in the United States, to adoption of other forms of dynamic data and authentication," Leach told the source. "By releasing the standard early, with long sunrise dates, organizations can evaluate the business case for their security investments."

Though there's no guarantee of how quickly the rest of the chip card transition will play out, or when more businesses will revamp their payment card processors, businesses can start paying attention to timelines that may affect their own adoption effort.
