Protect your card from double swiping.
The magnetic stripe on your credit or debit card contains sensitive payment card data.
To protect your information, the magnetic stripe of your credit or debit card should not be swiped on Point-of-Sale readers or Electronic Cash Registers which is known as “double swiping”.
Inserting or dipping a chip-enabled credit or debit card in a payment card terminal for payment is not considered as double swiping.
