How to Use the Fingerprint Module Interface in WizarPOS Terminals

Permission

Please add the following permissions to the manifest file of the application： <uses-permission android:name="android.permission.CLOUDPOS_FINGERPRINT" />

Crossmatch fingerprint

To learn how to develop fingerprint applications in devices with the Crossmatch fingerprint module, download the following SDK and documentation. The first TCS1FingerPrintSDK is a basic SDK. Please use it to input fingerprint and get image. If you want to compare or compress, use the second SDK-U.are.USDK. Note that the application cannot use the U.are.U SDK to input the fingerprint, so in the U.are.U SDK, the application cannot use the Reader class.

WizarPOS fingerprint

Specification

You can get WizarPOS FP spec here.

API document

Please find com.cloudpos.fingerprint from java api doc, if compare ISO 2005 template, please use method compare, compareByFormat and identify, if compare ANSI 378 template, please use method compareByFormat(byte[] arryBuffer1, int format1, byte[] arryBuffer2, int format2), if convert between ISO 2005 and ANSI 378 template format, please use convertFormat(byte[] dataBuffer, int srcFormat, int outFormat).

How to distinguish different fingerprint modules

There is a property called wp.fingerprint.model. If value is tuzhengbig, it is WizarPOS FP module; if value is crossmatch, it is Crossmatch fingerprint module. The code snippet is as follows:

   String prop = getProperty("wp.fingerprint.model","");
       if (prop.equalsIgnoreCase("none")) {
           showNormalDialog("tips", "No fingerprint module.");
       } else if (prop.equalsIgnoreCase("tuzhengbig")) {
          //WizarPOS FP
       } else if (prop.equalsIgnoreCase("crossmatch")) {
          //Crossmatch FP
       }    
   public static String getProperty(String key, String defaultValue) {
       String value = defaultValue;
       try {
           Class<?> c = Class.forName("android.os.SystemProperties");
           Method get = c.getMethod("get", String.class, String.class);
           value = (String)(get.invoke(c, key, defaultValue ));
       } catch (Exception e) {
           e.printStackTrace();
       }finally {
           return value;
       }
   }
