Encrypting Pin Pad
KY2145A IP65 Metal Encrypting PIN Pad
KY2145A is a stainless steel encrypting PIN pad built into a 145*100 mm front panel for unattended payment terminals.
Product Overview
KY2145A is a stainless steel encrypting PIN pad built into a 145*100 mm front panel for unattended payment terminals. It performs PIN encryption MAC calculation and data encryption and decryption on a dedicated security chip so plain PIN data never leaves the pad. It suits integrators adding card payment to ticket machines kiosks and ATMs that also need a water and vandal proof front.
- Hardware encryption model keeps PIN handling inside the security chip instead of the host PC
- IP65 rated water and vandal proof front for outdoor and unattended installations
- Front panel and overall footprint are both 145*100 mm so the cutout matches the part exactly
- USB PS/2 or RS232 interface lets the same pad drop into old and new terminal electronics
- Durability of at least 2 Million operations per key supports high traffic public sites
- A non-encryption model is available when the same layout is needed without secure PIN entry
Application Scenarios
- Ticket vending machines in metro and rail stations
- Self service kiosks that accept card payment
- Parking payment and exit terminals
- Automatic teller machines and cash recycling units
- Outdoor terminals exposed to rain and dust
- Retrofit of legacy RS232 payment terminals
Who It Is For
- Kiosk and ATM OEMs building card accepting terminals
- Payment terminal integrators who need panel mount PIN entry
- Transit ticketing system suppliers
- Parking system builders replacing plastic keypads
Problems It Solves
- Plastic PIN pads crack or are pried open at unattended sites
- Software PIN handling on the terminal PC widens the security boundary
- Rain and washdown reach the keypad face on outdoor machines
- Mixed legacy and modern hosts require different interfaces from one part number
Technical Features
- Advanced security chip with PIN encryption MAC calculation and data encryption and decryption
- Encryption support for MAC DES 3EDS and AES
- Password length 4~12 Bit and key length 8/16/24 bit
- Two by four function keys FDK beside the numeric block
- Key trip 1.5 mm with operation force 2~3N for confident entry through gloves
- Operation temperature -20 to 55 degrees C and storage temperature -30 to 85 degrees C
- Working current under 100mA from a DC5V plus or minus 5 percent supply

- FDK labelling matched to the payment application
How It Compares
| Plastic membrane PIN pad | Stainless steel buttons and a vandal proof front survive public sites where moulded plastic is attacked |
|---|---|
| Host based software PIN entry | Hardware encryption in the pad keeps PIN and key material off the terminal PC |
| USB only PIN pads | USB PS/2 or RS232 lets one mechanical design serve both new and legacy controllers |
Use Guide
- Cut the panel to the 145*100 mm outline before mounting
- Supply DC5V plus or minus 5 percent and allow for under 100mA draw
- Select the interface variant that matches the host before ordering
- Keep ambient within -20 to 55 degrees C during operation
- Store spare units between -30 and 85 degrees C
