New legal requirements for this start on October 1.
[New credit cards that help prevent fraud] require new devices to read them, and [churches that] process transactions will need to be trained on the new procedures. Instead of swiping the magnetic strip, the card will be “dipped” into the device, which can read the chip, authenticate it, and then require a PIN or signature from the card holder.
To encourage adoption of the latest technology, liability for fraud will change on October 1. Traditionally, credit card companies or banks issuing cards were responsible for any fraud that occurred with the card. Beginning October 1, however, whoever uses the older card system will be liable. This means that churches processing payments on EMV cards with old devices could be on the hook if they process an upgraded card with an old magnetic strip card reader.
As more and more retail stores and other outlets make the switch to the new technology, fraudulent activity will no doubt increase where systems are most vulnerable—and this could certainly include churches with dated readers.
