Question: Which computer configuration should I use?

Answer:

For databases up to 1,000 fingerprints there are no big requirements. Any PC can be used, like a Celeron 1 GHz with 128MB RAM.
For databases up to 10,000 fingerprints it is recommended to use a dedicated PC to keep the 1 per second speed in the identification process. A proper configuration would be a Pentium 4 with 512MB RAM. A 800Mhz Bus is very important and makes a great difference in the performance.
For databases higher than 10,000 fingerprints it is important to use a multiple paralel servers architecture, the SpeedCluster. This way you will have many servers searching for the fingerprint, which makes the process faster.
In case of unique use of Verification method, a heavy server structure is not required. Only one calculation of a fingerprint is computed and then, it will be compared to a stored fingerprint. Unless many requests are made at the very same time, one server is enough; even a shared one.
