With the advent of computers and electronic communications a large number of alternative electronic payment systems have emerged. These include debit cards, credit cards, electronic funds transfers, direct credits, direct debits, internet banking and e-commerce payment systems. Some payment systems include credit mechanisms, but that is essentially a different aspect of payment. Payment systems are used in lieu of tendering cash in domestic and international transactions and consist of a major service provided by banks and other financial institutions. Payment systems may be physical or electronic and each has their own procedures and protocols. They are securely transmitting informations and transactions to a server for authentication and approval. Examples of payment systems that have become globally available are credit card and automated teller machine networks. Mobile payment or known also as Mobile wallet is an alternative payment method. Instead of paying with cash, cheque or credit cards, a consumer can use a mobile phone to pay for a wide range of services and digital or hard goods." page 2 Payment Systems : Communication, GPRS Inductor Product Name Status ILBB… Description Multilayer Ferrite Beads 7Ω to 2200Ω at 100 MHz Features Magnetically self shielded Package Q-Level SMD 0805 Schottky diode Product Name Status Description Features Package MSS1P3L 30V, 1A 0.35V at 1.0A SMD Micro SMP SSA34 40V, 3A 0.42V at 3.0A SMA Q-Level Switching MOSFET Product Name Status Si1032X Description N-channel 20V MOSFET VDS = 20V ; ID = 200mA ; rds(on) = 5Ω Features Low threshold (1.5V) Package Q-Level SMD SC89 Transient Voltage Suppressor Product Name SMBJ… Status Description Uni-directionnal, Bi-directionnal, 600W 5.0V - 188V Features Excellent Clamping Capability Very Fast Response time Package Q-Level DO-214AA page 3 Payment Systems : Communication, IR Communication Infrared Emitting Product Name Status VSMB20… Description High Speed Infrared Emitting Diode 940nm, +/- 12° Features High radiant intensity, Low forward voltage for high pulse current Package Q-Level SMD Reciever Product Name VEMD20… Status Description High Speed Silicon PIN photodiode 830 nm - 950 nm, +/- 15° Features High radiant sensitivity Fast response time Package Q-Level SMD page 4 Payment Systems : Communication, NFC Inductor Product Name IMC0805-01 Status Description Surface Mount Inductors Features 10nH to 1mH Package Q-Level SMD 0805 page 5 Payment Systems : Peripherals, Printer Power MOSFET Product Name Si4116DY Status Description N-channel 25V MOSFET VDS = 25V ; ID = 18A ; rds(on) = 8.6 mΩ Features Low threshold Package Q-Level SMD SO8 page 6 Payment Systems : Peripherals, USB ESD protection diode Product Name VBUS051BD Status Description Single Line ESD protection device ESD Immunity > 15 kV Features Low capacitance Ultra Compact package High surge current Package Q-Level LLP1006-2L page 7 Payment Systems : Power Supply, Charge control Load switch Product Name Status Si2301 Description P-channel 20V MOSFET Features VDS = -20V ID = -3.1 A rds(on) = 112 mΩ Package Q-Level SOT-23 Temperature Sensing Product Name NTCS0805E3 Status Description Glass protected NTC thermistor Tolerance on R25 down to 1% Tolerance on B25/85 down to 1% Features Package Q-Level SMD 0805 page 8 Payment Systems : Power Supply, EMI Filtering Y Capacitors Product Name Status Description Features VY1 series AC Line Rated Disc Capacitors Class Y1 500 Vac 10pF to 4.7nF Complying IEC 60384-14 VY2 AC Line Rated Disc Capacitors Class Y2 300Vac 10pF to 10nF Complying IEC 60384-14 High reliability Package Q-Level page 9 Payment Systems : Power Supply, Switch Mode Regulator High Side MOSFET Product Name Status Si7633DP Description P-channel 20V MOSFET Features VDS = -20V ID = -60A rds(on) = 3.3 mΩ Package Q-Level PPAK-SO8 Inductor Product Name Status IHLP2525 Description Low Profile High Current Inductor 0,1µH to 10 µH - Isat = 7 to 60A Features Package Q-Level Package Q-Level Shielded construction lowest height 1.8mm Low Side MOSFET Product Name SIS402DN Status Description N-channel 30V MOSFET Features VDS = 30V ID = 35A rds(on) = 6mΩ PPAK 1212-8 page 10 Payment Systems : User Interface, Keyboard 6-channels EMI Filter + ESD protection Product Name VEMI65AC Status Description Line Resistance = 100Ω, Cut off frequency = 240Mhz ESD immunity > 12 kV Features Low leakage current Package Q-Level LLP2513-13L page 11 page 12
