In My case it was ibGoogleAnalytics_debug.a library. To find which library is using uniqueidentifier method, go to your project folder and type in: $ find . | grep -v .svn | grep “\.a” | grep -v “\.app” | xargs grep uniqueIdentifier I got this: Binary file ./My_Project/libGoogleAnalytics_debug.a matches
You can get the GUID back by using OUTPUT. This works when you’re inserting multiple records also. CREATE TABLE dbo.GuidPk ( ColGuid uniqueidentifier NOT NULL DEFAULT NewSequentialID(), Col2 int NOT NULL ) GO DECLARE @op TABLE ( ColGuid uniqueidentifier ) INSERT INTO dbo.GuidPk ( Col2 ) OUTPUT inserted.ColGuid INTO @op VALUES (1) SELECT * FROM … Read more
Check into this thread,. However you should be careful as it’s documented as “can change upon factory reset”. Use at your own risk, and it can be easily changed on a rooted phone.

This is (at least with the official API) not possible: In the first part of the exchange the HCE device will present its UID; HCE devices should be assumed to have a random UID. This means that on every tap, the UID that is presented to the reader will be a randomly generated UID. Because … Read more
How about adding motherboard serial number as well e.g.: using System.management; //Code for retrieving motherboard’s serial number ManagementObjectSearcher MOS = new ManagementObjectSearcher(“Select * From Win32_BaseBoard”); foreach (ManagementObject getserial in MOS.Get()) { textBox1.Text = getserial[“SerialNumber”].ToString(); } //Code for retrieving Processor’s Identity MOS = new ManagementObjectSearcher(“Select * From Win32_processor”); foreach (ManagementObject getPID in MOS.Get()) { textBox2.Text = … Read more
As selected answer says you can use findAndModify to generate sequential IDs. But I strongly disagree with opinion that you should not do that. It all depends on your business needs. Having 12-byte ID may be very resource consuming and cause significant scalability issues in future. I have detailed answer here.
