YES, it should work with your existing time & Attendance software. You do NOT have to change the software to Amano software. If you are using ID card based readers with it, almost all cases you can use them without any modification of the software side. Most of the readers used for Time Management or Door Access Control pass the data to PC application in ASCII text data file format. Our communication software called Acepoll for Windows enables you to transfer all punch data form connected readers to you PC and then save the data in specified format. So we can create exactly the same data files as your current ID card readers. Almost all Time & Attendance software deal with ID card readers, so you can use this HGRs as a replacement of your current readers.
