Yup, the project was done. Anyway, I’ll wait for the complete sdk from fingetec and recode them all over again. Instead of relying too much on ftdp which made the performance came up poor, I’ll try the low level sdk. At least i’ll save up half of the cpu consumption by running only my code of data retrieval routine from the terminal. Additionally i could save up the io cost by reducing the db roundtrip by using only single db, eliminating the usage of ms access by ftdp.. 🙂
