SR2500 Series Mifare Reader
This SR2501GT series card access reader can be used for energy saving function, time attendance as well as access control function. This reader uses Mifare technology to provide secured access control and e-payment function.
Mifare technology is well suitable for both access control and payment function due to its secured authentication algorithm. The memory spaces in the smart card are segmented into sixteen regions and each region is locked by a security code. To open a memory region for processing, the security code in the smart card has to be matched with corresponding key code in the reader. For access control function, one region will be allocated using a chosen key code upon agreement with the system owner / management. For payment function, another region will be allocated using different key code if so desired
