Encrypting Pin Pad
KY3088D Encrypting Pin Pad With Raised or Flat Key Option
KY3088D is an encrypting pin pad that can be built with either 1.5mm raised keys or 0.45mm flat keys on the same 87.5*91.5mm face and 140*95mm body, so accessibility and tamper resistance can be traded off per project.
Product Overview
KY3088D is an encrypting pin pad that can be built with either 1.5mm raised keys or 0.45mm flat keys on the same 87.5*91.5mm face and 140*95mm body, so accessibility and tamper resistance can be traded off per project. Hardware encryption handles PIN encryption, MAC calculation and data encryption and decryption. It targets self-service payment, fuel, vending and ATM equipment.
- One part number covers 1.5mm raised keys or 0.45mm flat keys
- Accessibility and anti-tamper needs can be met without a new panel design
- Hardware encryption chip keeps PIN data off the host application
- Encryption supports MAC, DES(3EDS) and SM4 for different regions
- 2*4 Function keys (FDK) for screen-side selection
- USB, PS/2 or RS232 at DC5V±5% with under 100mA
Application Scenarios
- Self-service payment solutions in retail and transport
- Self-service petrol filling stations on the forecourt
- Vending machines taking card payments
- Automatic Teller Machine PIN entry positions
Who It Is For
- Fuel dispenser and forecourt terminal manufacturers
- Vending machine OEMs adding card payment
- Self-service payment terminal integrators
- ATM builders standardising on a 140*95mm cut-out
Problems It Solves
- Choosing between tactile raised keys and tamper-resistant flat keys at design stage
- Redesigning a fascia when the key style changes
- PIN processing handled in terminal software
- Regional algorithm requirements varying across a rollout
- Serial-only controllers in older dispenser electronics
Technical Features
- Stainless steel buttons in a water and vandal proof compact layout
- Key Trip 1.5mm (raised keys) or 0.45mm (flat keys)
- Hardware Encryption model with a security chip, non-encryption model supported
- Password length 4~12 Bit with key length 8/16/24 bit
- Operation force 2-3N with durability ≥2 Million
- Operating temperature -20 ℃~55℃, storage temperature -30℃~85℃

How It Compares
| KY3088B metal pinpad | Same 87.5*91.5mm face and 140*95mm body, but KY3088D also offers a 1.5mm raised key build. |
|---|---|
| KY3080 encrypting pin pad | KY3088D keeps the 140*95mm mounting body, while KY3080 is flush at 88*77 mm front and overall. |
| Fixed flat-key pin pads | The key style is selectable at order rather than fixed by the panel design. |
Use Guide
- Decide raised or flat keys at order stage as the key trip differs
- Cut the face to 87.5*91.5mm and allow the 140*95mm body
- Confirm the algorithms and password length with your acquirer requirements
- Supply DC5V±5% with under 100mA available
- Operate within -20 ℃~55℃ and store within -30℃~85℃
