How do RFID chips impact card payment?

In addition to the chip-based EMV cards becoming more common in the United States, businesses may have to prepare for radio frequency identification (RFID) chips, which reportedly bring added security with them. As with other improvements to card processing software, however, installing RFID can be a time and cost-intensive process for businesses that need to fully revamp.

There are multiple kinds of technologies that could be built into RFID systems for better accuracy. One of these includes miniature lighting fixtures that can act as a special RFID scanner.This shows how the use of this chip brings with it new hardware as well as software, necessitating complete oversight during a systems change.

Part of what makes these chips potentially attractive to shop owners is the specific way they safeguard against encryption failures. In an article for Gizmag from earlier this month, MIT engineering student Chiraag Juvekar describes the side-channel attacks that upcoming technology could specifically prevent against.

"The idea in a side-channel attack is that a given execution of the cryptographic algorithm only leaks a slight amount of information," Juvekar said."So you need to execute the cryptographic algorithm with the same secret many, many times to get enough leakage to extract a complete secret." Since attacks can be automated, the protection card users rely on should be comprehensive to guard against dangers effectively.

Whether or not they adopt this particular approach, addressing credit card payment software puts businesses at a potentially better place to welcome customers and assure them of safe transactions. Taking time to assess whether a software option will fit your system, and how long it will take to make sure it does, influences how feasible a new update will be.
