1. Integrated image collecting and algorithm chip together, integration2. The flexibility to adapt to the conditions was the fingers, whether it is dry fingers, wet fingers, light texture fingerprints fingers, and old fingers, all have high recognition rate3. The main application areas: can be embedded into a variety of end products, such as: access control, attendance, safety deposit box4. The R503 fingerprint module has a built-in algorithm chip5. The interface line spacing is 1.0mm, and the line length is 20cm. Thread diameter is 25mm, easy to install.Supply voltage: DC 3.3VWorking current: 30mA (typ.)Peak current: 40mAFingerprint image entry time: Less than 0.3 secondsAcquisition window area: 15mm in diameterImage pixel: 192*192 pixelImage Resolution: 508dpiMatch method:Comparison method (1:1)Search method (1:N)Storage capacity: 200 piecesSecurity level: five (from low to high: 1, 2, 3, 4, 5)False Recognition Rate (FAR): Less than 0.0001%Authentic rejection rate (FRR): Less than 1.0%Search time: Less than 0.3 seconds (1:1000, average)Host computer interface: RS232 (TTL logic level, 3.3V)Communication baud rate: (9600xN)bps where N=1~12 (default value N=6, ie 57600bps)working environment:Temperature: -20Celsius-+45CelsiusRelative humidity: 10%RH-85%RH (non-condensing)Colour:silverMaterial:Plastic + MetalSize:Fingerprint module height: 19mm/15mm/32mm Package Contents:1 x Barcode Scanner ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
