With MCR-EVO-K1 our goal was to do the impossible: engineer a full-size experience into the smallest and most compact wireless MCR ever. That meant reengineering every element to make it not only smaller and thinner but also better from every point of view. The result is a very reliable brand new MCR with keypad facility and Bluetooth communication. And now, with a very fast processor, improved reading performance, faster and bigger memory storage, the smallest controlled power consumption, the MCR-EVO-K1 is truly the smallest and best magnetic stripe card reader on the market with keypad facility and wireless communication.

The Bluetooth can be controlled for how long to be ON (when consumes 4mAh/h) and OFF (when will consume 0.13mAh/h) so it will save a lot of power.


For example, the bluetooth can be set to ON for 10 minutes and OFF for 2 hours, and will turn on automatically for 10 minutes in which time the connection to the device can be made so the files can be downloaded, erased, made another settings etc., and sleep for another 2 hours in which time the device will work as normal but only the connection to it cannot be made. This cicle will repeat until the device is turned OFF or another setting is made. Please read the User Manual for more info.

Field (with no interference - Ideal conditions)                           City (with buildings interference)
100m                             30m


Large memory: 8Mb or 128,000 swipes

Working current: 1.8V - 5.9V.

This means that it can be powered with 2 very small 1.5V watch batteries, and also from a 5V USB socket for continuous power.

Data saved into the memory is verified that it has been saved correctly. This prevents data loss like sometimes happens to other devices on the market.

We have added a Firmware Update feature directly from our computer software.
