The invention discloses a high-speed optical receiver module of an integrated limiting amplifier and a preparation method for the high-speed optical receiver module. The optical receiver module is formed by connecting a tube socket, a tube cap, an adapter, a photoelectric receiver, a monolithic integration high-speed limiting amplifier chip and a flexible printed circuit board, wherein the photoelectric receiver, the monolithic integration high-speed limiting amplifier chip and the flexible printed circuit board are connected with each other. The preparation method for the high-speed optical receiver module comprises the following steps: firstly mounting the photoelectric receiver and the monolithic integration high-speed limiting amplifier chip onto the tube socket; then, welding the photoelectric receiver and the input end of the monolithic integration high-speed limiting amplifier chip together by using a gold wire bonder, and meanwhile, welding a bonding pad of the monolithic integration high-speed limiting amplifier chip and pins of the tube socket together; then, sealing the tube cap by adopting a cap sealing machine; subsequently, performing light path alignment on the tube cap, and then, fixing the adapter to the tube cap; and finally, enabling the flexible printed circuit board to sheathe the roots of the pins of the socket and welding to fix the flexible printed circuit board. According to the high-speed optical receiver module of the integrated limiting amplifier disclosed by the invention, the space of the rear end module design is saved, a packaging design can be flexibly realized, and meanwhile, the power consumption and the cost of a whole module application system are also reduced.

A payment terminal 10 includes a payment card reader 40, which obtains payment data, preferably from a contactless payment unit or card 40 that is physically close to the terminal 10. A secondary reader (not shown) obtains supplementary data (211, fig.3) from a machine readable entity such as a passport or travel document. The secondary reader may comprise a radio frequency transceiver. The secondary data is combined with the payment data to form a payment record, and thus makes the payment by contactless methods more secure by providing greater assurance as to the identity of the customer. A method of payment and a payment system are also disclosed. The payment means may alternatively be a NFC payment device, or a chip and pin device.

Embodiments automatically select one of the multiple pre-generated payment cards provisioned on a mobile device. The multiple pre-generated payment cards (real or virtual) may each have a different credit limit. The mobile device may automatically select one of the multiple payment cards based on a transaction value of a transaction that is being conducted. An available credit limit of the selected payment card may be equal to or slightly greater than the transaction value. In some embodiments, the available credit limit of the selected payment card may be closer to the transaction value than the available credit limits of the remaining payment cards. In some embodiments, the different payment cards may be provisioned in a chip-and-pin based smart credit card or mobile wallet.

A secure non-volatile solid state memory data key appears similar to a conventional USB flash drive modified to have a physical shape resembling a door key with an eyelet for attaching the data key to a key ring or lanyard. The data key includes a USB port, a microprocessor (effectively serving as the “chip” in the chip-and-pin configuration), and a secure memory for holding secure transaction information, such as credit and debit card numbers, verified personal identification (federated ID), and other secure data. The data key may include a dual-purpose electrical contact that serves both as a four-pin USB contact and an eight-pin chip-and-pin contact. Another example is a data key with a near-field communication (NFC) receiver that allows to data key to turn a smartphone, laptop or other computer into an NFC merchant terminal.
