We need to develop a Time and Attendance Punch Clock with the following specs.
- 10/100 Wired Ethernet
- 4x4 Matrix Keypad (We should prefer a capacitive Touch keypad with IC AT42QT2120)
- Bi Color LED
- Solid State Relay
- Graphic Display
- 1 MB Flash
- 2 Wiegand Ports
- 2 serial Ports, one RS232 Level and one TTL Level (To be used with a Serial Fingerprint Sensor)
- On board 3.3VDC and 5 VDC (Input Voltage 12 VDC-24VDC)
- Real Time Clock with LiON Battery Backup
Nice to have:
- Fingerprint and Punch Clock Data Accesible using FTP
- http for config
- Store 30,000 Punch clock info, when the max number is reached delete the old one
- We need a Find & Discovery Solution using UDP (We need to find clocks in the Net and config new IP)
- We should be able to store a new firmware using UDP utility (Update using Ethernet, not special cables)
- Can send punch clock information online, also can retrieve config parameters from the net/cloud
- Can be used as DHCP or Fixed IP
It is important to keep in mind that we need a PCB that can be easily populated without the need of special pick and place machines, No BGA or similar ICs.
