Have you ever been given a card instead of a key to open your hotel room door? Ever wondered
how your key knew which door to open or if someone else's card can open yours? Fear no more,
technology is on your side. The key you hold is the only key that has the proper magnetic
strip to disengage the lock on your door.
A card reader similar to the ones used to access hotel rooms was designed to scan personal
ID cards to determine access eligibility to secured doors, gates, or other entry systems.
The system works similar to systems found in hotels - a person swipes an ID card through
the card reader, whereupon the card reader sends encoded data to a host computer. If the
person is authorized, the computer illuminates the PERMIT indicator and releases the door
during entry. If the person is not authorized, the DENY indicator turns on and the door
remains locked.
Certain requirements are placed on a system of this type, the system must have addressable
memory up to 256K bytes, it must have an on-board real-time clock for time and date stamping,
and it must have the outputs to engage and disengage door relays. Finally, the system must
be cost-effective, or keys would be the more economical solution.
To satisfy these requirements, Z-World's BL1500 SBC and proprietary development software,
Dynamic C® were combined together to create this solution. The Z-World BL1500 controller
is the heart of the card reader. The BL1500 provides the CPU, memory, real-time clock and
I/O channels for system control. Outputs engage four relays on the card reader motherboard
that connect to entry system locks. The on-board real-time clock keeps the correct time
and date. On-board memory stores a database of all card holders. The BL1500 is equipped
to operate off-line, logging transactions until communications with a host computer are
restored.
Why Z-World?
- Provided CPU, memory and all I/O needed.
- Standard RS-485 communication line for computer link.
- Provided a lot of functionality for the price.
