Supporting a wide-range of contactless payment applications, our ASIC solutions include near-field communication (NFC), energy harvesting, and security.

Closed Loop Payment

Many organizations are taking proactive steps today to improve their customers’ experience in contactless payment.

Closed-loop payment devices, which are used with a specific payee, are rapidly increasing in popularity in various markets like biometric sensing, access cards for transportation, loyalty/gift cards, prepaid cell phone cards, gas station refueling cards and parking cards.

Contactless payment components

A contactless payment incorporates a custom ASIC or integrated circuit (IC) for managing power, data storage, and security functions, like fingerprint biometrics or standard EMV transactions.

Common payment device functions

NFC (Near Field Communication)

Enables close-range communications between the payment device and an NFC reader (terminal) and passes encrypted information to complete secure payments.

Processor

Supports the payment device functionality and security, handling the multiple interfaces for contactless applications.

Flash

Store memory keys and data, allowing the memory card to store data without having to pass data to terminal.

Power management

Allows payment devices to operate by taking the energy needed from the payment terminal using NFC (Near Field Communication) technology.

Biometric sensor

Processes and communicates biometric fingerprint information securely to verify payment.

NFC frontend IP

The Presto NFC transceiver uses the 13.56MHz RFID frequency so support close-range communications between payment devices and NFC readers and pass encrypted information to complete secure payments. Based on GLOBALFOUNDRIES 55nm PX technology, the transceiver offers low-power and low voltage operation.

 

 

Energy Harvesting and Power Management IP

Eliminating the need for a battery or external power supply, our ASIC solution harvests energy from the payment terminal over Near Field Communication (NFC) technology, enabling both active and passive payment devices to operate flawlessly.

A power management module controls efficient storage and usage of power, managing the load and sleep operations and helping the payment device achieve an energy neutral operation. It supports the power and charging requirements of biometric fingerprint sensors.
