Abstract: A fingerprint identification module test system includes a light source, a projection surface, a low-end image pickup device and a judgment module. The light source emits and projects a light beam onto an under-test fingerprint identification module. After the light beam is reflected by the under-test fingerprint identification module and projected onto the projection surface, a projected image is formed on the projection surface. Then, the low-end image pickup device photographs the projected image to acquire an under-test corresponding to the under-test fingerprint identification module. According to the result of comparing the under-test image with the predetermined image, the judgment module judges whether the under-test fingerprint identification module complies with the production specifications. Since the fingerprint identification module test system uses parity devices to test the under-test fingerprint identification module, the fingerprint identification module test system is cost-effective.
