KY3689 PCI Certified Encrypting Metal Pin Pad
KY3689 is an encrypting pin pad for unattended payment and identity terminals, with DES and AES support and PCI 1.3 certification.
Product Overview
KY3689 is an encrypting pin pad for unattended payment and identity terminals, with DES and AES support and PCI 1.3 certification. The SUS304 panel carries IK07 impact and IP65 water and dust ratings, and Braille or graphic keycaps are available for accessibility requirements. It connects over RS232 to a terminal controller.
- Passed PCI 1.3 certification, so acquirer approval work starts from a certified device
- DES and AES support covers common acquirer key schemes
- IP65 waterproof and dustproof rating suits outdoor and forecourt installations
- IK07 explosion proof rating resists deliberate impact at unattended sites
- Braille or graphic keycaps are optional for accessibility legislation
- ESD 4K protection guards against static discharge in dry public areas

Application Scenarios
- Unattended payment kiosks and forecourt terminals
- ATM and cash recycler pin entry positions
- Ticket vending machines taking card payment

How It Compares
| Non-certified metal keypad | PCI 1.3 certification and DES and AES support allow use where plain keypads cannot handle pin entry |
|---|---|
| Indoor pin pad | IP65 and IK07 ratings let the unit sit in weather-exposed unattended positions |
| Plastic pin pad | A SUS304 face resists the prying and impact that plastic fascias fail under |
Use Guide
- Plan RS232 wiring and key loading with your acquirer before installation
- Maintain the IP65 seal by using the supplied gasket and torque pattern
- Supply 5V±5% within the <150mA working current budget
- Operate within -10℃~45℃ and store within -30℃~85℃
- Specify Braille or graphic keycaps at order if accessibility rules apply
