PCI Encrypting Pin Pad
KY3688H Metal EPP PCI 5.0 Encrypting Pin Pad
KY3688H is a metal encrypting pin pad (EPP) for attended and unattended payment points, certified to PCI 5.0 and carrying CE, ROHS, FCC, IP65 and IK7.
Product Overview
KY3688H is a metal encrypting pin pad (EPP) for attended and unattended payment points, certified to PCI 5.0 and carrying CE, ROHS, FCC, IP65 and IK7. It uses a physical 16 key layout with defined keys including braille and communicates over an RS232 serial port. The temperature range of -40°C ~ 105°C covers outdoor terminals in extreme climates.
- PCI 5.0 certification with CE, ROHS, FCC, IP65 and IK7 shortens terminal approval work
- 3DES, AES, SHA256 and RSA cover the algorithm sets acquirers ask for
- Temperature range -40°C ~ 105°C lets one part serve cold and hot climates
- MTBF above 42950 gives a documented reliability figure for tender responses
- Remote key loading avoids sending technicians to each terminal
- 87.5*91.5 mm footprint fits compact unattended fascias
Application Scenarios
- Unattended fuel and parking payment terminals
- ATM and cash machine pin entry
- Attended retail payment positions
- Transport ticket machines accepting cards
- Outdoor vending with card payment in extreme climates
Who It Is For
- Payment terminal and ATM manufacturers
- Acquirer-facing kiosk integrators
- Fuel forecourt equipment suppliers
- Transport ticketing OEMs
Problems It Solves
- Terminal approval stalls without a current PCI certified pin entry device
- Field key loading is costly when it needs an engineer visit
- Pin pads fail outside a narrow temperature band in outdoor cabinets
- Accessibility rules require braille on the key layout
Technical Features
- PIN entry technology physical keypad, class PED, evaluated online
- Key number 16 covering Master Key, PIN Key, Mac Key and Data Key
- Key management MK/SK with remote key loading
- Algorithms 3DES, AES, SHA256, RSA to ISO9564-1 0 / 1 / 3 / 4, ANSI X9.8, ANSI X9.19, ECB, CBC
- Operating voltage 5.0V ±10% with battery voltage 3.0V ±10%
- ESD 8K and current <40mA
- Material #304 with a defined layout including braille

Materials
- #304 stainless steel
- Tamper-responsive secure keypad module
Manufacturing Process
- Sheet-metal forming of the #304 panel to the 87.5*91.5 mm outline
- Panel brushing and key aperture punching
- Etching of the defined layout including braille
- Secure module assembly with tamper response
- IP65 sealing and impact reinforcement
- Remote key loading setup and security validation
Quality Control
- Security behaviour tested against the PCI 5.0 certified configuration
- ESD immunity verified to the 8K rating
- Current draw checked below 40mA
- Temperature cycling across the -40°C ~ 105°C range
- RS232 communication validated against a host terminal
Approvals And Test Documentation
- PCI 5.0
- CE
- ROHS
- FCC
- IP65
- IK7
Customisation Options
- Key layout defined with braille as required
- Panel outline and fixing to match the terminal fascia
- Key management and remote loading configured to the acquirer scheme
- Cable and connector arrangement for the RS232 serial port
- OEM and ODM builds from the KEYU factory in Shenzhen
How It Compares
| PCI 1.3 pin pad | PCI 5.0 certification meets the newer scheme requirement where the older approval is no longer accepted |
|---|---|
| Indoor-rated pin pad | A -40°C ~ 105°C range and IP65 rating allow outdoor unattended deployment |
| Plastic EPP | A #304 metal body with IK7 rating resists attack on unattended terminals |
Use Guide
- Agree the MK/SK key scheme and remote loading process with your acquirer first
- Wire the RS232 serial port and supply 5.0V ±10% to the module
- Keep the backup battery at 3.0V ±10% so tamper detection stays active
- Preserve the IP65 seal when fitting to the terminal fascia
- Do not open the secure module as tamper response will trigger
