MMD-1900

The MMD-1900 integrates the magnetic card reader head with data encryption. Upon reception of the magnetic head signals, the card data is recovered, encrypted, and transferred to the external device.

• UART or SPI interface
• Wide range of card swipe speeds: from 5 to 150 cm/s
• Secure data transfer with 128-bit AES encryption
• ISO 7810/7811 and AAMVA
