In an effort to accelerate the adoption of chip cards in the United States, something called the liability shift happened in October Under the liability shift, sellers who continue to swipe chip cards could be on the hook for certain kinds of fraud. No one wants that, so it makes sense for sellers to get a card reader that accepts chip cards.

If you purchase a contactless and chip reader, Square covers you for the liability shift until your reader arrives. Have customers without chip cards? Not a problem. The reader comes with a magstripe reader so you can swipe cards without chips.

However, unlike magstripe cards, where the payment info is static, chip card data keeps changing, which makes it extremely difficult for fraudsters to extract anything useful. When a chip card is dipped into a chip card reader, the chip and reader communicate with each other in an encrypted language. A new code is created for each transaction and the data is encrypted the moment the card is dipped. The encrypted data is then sent to the acquirer as explained above.

But while chip card payments are extremely secure, the processing time is slower than it is with magstripe cards. All those security checks make the transaction take longer. This sluggishness can be particularly irritating if your business is one that typically has long lines to check out. Contactless NFC payments, on the other hand, are much much faster. Like chip cards, NFC data is both encrypted and dynamic, which means it changes for every transaction.
