Technology Highlights

• The invention technology uses contactless cards that communicate with a reader through radio frequency waves, which enables faster transactions.
• The invention contactless communication between the buyer's device and the seller's device (called NFC) is also used by smartphones that emulate a chip card in a digital wallet.
• The invention system allows reliable identification of both parties (buyer and seller) to ensure that they are the genuine owners of their respective devices.
• The invention ensures that neither party can later deny or refuse the digital transaction once it has been carried out.
