What are RFID cards used for?

RFID technology encompasses a wide range of products, including tags and readers. A reader is a device that can communicate with RFID tags, providing various applications and benefits. An RFID reader is a network-connected device that uses radio waves to transmit signals and communicate with RFID tags. It can read and write data to both contact and contactless tags, allowing you to activate and interact with them. Learn more about this technology and its uses. Discover how low-frequency (LF), high-frequency (HF), and ultra-high-frequency (UHF) RFID systems can be used for access control, loyalty programs, parking barriers, and asset management. Explore the benefits and learn how to improve your operations with RFID technology. An active RFID tag is an advanced tracking device with its own battery, allowing for extended range and continuous data transmission. 

  Low-frequency RFID systems operate within a frequency range of 30 KHz to 500 KHz. These systems are commonly used for short-range applications, typically ranging from a few inches to under six feet. Gain insight into the functionalities and applications of low-frequency RFID systems.

High-frequency RFID systems operate within a frequency range of 3 MHz to 30 MHz, with the typical frequency being 13.56 MHz. Discover how these systems work and their applications.

UHF RFID systems, operating in the frequency range of 300 to 960 MHz, are commonly used for various applications, including parking barriers.

List Of Applications Using RFID Cards

RFID cards are a form of identification that uses radio frequency technology to wirelessly transmit data between a card and a reader. They often use PVC material and can include various chips, such as MIFARE or proximity chips. 

1. RFID access control systems use biometric technology to identify individuals and grant them access. Learn how to issue cards, encode identification information, and ensure each card has a unique number, such as a card serial number (CSN). Implementing these measures will enhance security and manage access control more effectively.
2. UHF asset management systems utilize radio frequency identification (RFID) technology to track and manage physical assets such as supermarket jewelry.
3. Track vehicles using UHF tags in a school application connected to a central database. This system enables real-time tracking and provides signals to parents and school authorities for enhanced safety and security.

When you open the report, the data source of the report connects to SQL Server 2008 Analysis Services by using the data source credential. After the connection is established, successive requests to SQL Server 2008 Analysis Services do not reuse the data source credential. Instead, successive requests use the credential of the current user. This causes the problem that is mentioned in the "Symptoms" section.

Error message when you install SQL Server 2005 SP2, SQL Server Express SP2, or SQL Server Express with Advanced Services SP2: "SQL Server Setup failed

A web application that attempts to create a database or read/write to a database using SQL Server Express user instance mode can encounter any of the following errors: Error message when you install SQL Server 2005 SP2, SQL Server Express SP2, or SQL Server Express with Advanced Services SP2: "SQL Server Setup failed to execute a command for server configuration. CREATE DATABASE failed" A web application relies on SQL Server Express' user instance mode if either of the following is true: The application relies on the default "LocalSQLServer" connection string defined in machine.config The application uses a connection string that contains the following attributes: "AttachDBFilename=|DataDirectory|xxxxxx.mdf;User Instance=true" Resolution for Web Application Projects and Websites TACS LLC Dubai Time Attendance Dubai Access Control System Gate Barrier HRMS Solutions EID Reader Software EID Reader Building Maintanance UHF Reader For web application projects (WAP) and websites located in a user's Documents Folder hosted under any version of IIS running as NETWORK SERVICE, carry out the following steps: First confirm that IIS has been configured to run as NETWORK SERVICE. This is the default on IIS6 and IIS7. However if you are running on Windows 7 or Window Server 2008 R2 you will first need to follow the steps above in "Resolution for Windows 7 and Windows Server 2008 R2" to make IIS application pools run as NETWORK SERVICE. From a command prompt, type net stop iisadmin /y . This will cause any running ASP.NET WAP applications to shutdown. Exit out of all running Visual Studio instances. NETWORK SERVICE must be granted Read permission to the top-level Visual Studio folder located in your user's Documents folder. The Visual Studio folder will have different names depending on the version: "Visual Studio 2005", "Visual Studio 2008", or "Visual Studio 2010". NETWORK SERVICE must be granted both read and write permissions to your project's top-level project folder. For example if your WAP project is called "MyCustomWebProject", then the folder "Documents\Visual Studio 20xx\Projects\MyCustomWebProject" needs to have read and write access enabled for NETWORK SERVICE. Or, if your webiste project is called "MyCustomWebProject", then the folder "Documents\Visual Studio 20xx\Websites\MyCustomWebProject" needs to have read and write access enabled for NETWORK SERVICE. NETWORK SERVICE must be granted both read and write permissions to the App_Data folder located within your web project's directory structure.

You should provide default values for all form fields that are used in the query.

The following error may come when you are trying to install sql server express edition on computer running windows vista

SQL Server Setup failed to execute a command for server configuration. The error was [Microsoft][SQL Native Client][SQL Server]Windows NT user or group 'COMPUTERNAME\SQLServer2005MSSQLUser$COMPUTERNAME$MSSQLSERVER' not found. Check the name again.. Refer to the server error logs for detailed error information.

This problem occurs if the following conditions are true: The Windows Vista-based computer has a name that consists of lowercase characters or that consists of a mixture of lowercase characters and uppercase characters. For example, the computer name resembles Workstation-1. You specify a case-sensitive collation setting for the SQL Server service when you install SQL Server 2005 Express Edition SP1. Windows Vista uses the following two methods to return the computer name in response to a request for the computer name: Windows Vista can return the computer name in uppercase characters. Windows Vista can return the computer name in the actual mixed case characters that appear in the System Properties dialog box. During one part of the installation of SQL Server 2005 Express Edition, the Setup program requests the computer name as mixed characters. However, Windows Vista returns the computer name in uppercase characters instead. The Setup program also requests the computer name in other parts of the installation of SQL Server 2005 Express Edition. Windows Vista may then return the computer name in mixed case characters. TACS LLC Dubai Time Attendance Dubai Access Control System Gate Barrier HRMS Solutions EID Reader Software EID Reader Building Maintanance UHF Reader The SQL Server 2005 Express Edition Setup program compares the received computer names. Generally, this does not cause a problem because computer names are not case sensitive in Windows Vista. However, if a case-sensitive collating sequence is specified when you install SQL Server 2005 Express Edition, the result of the name comparison between the computer name in uppercase characters and the computer name in mixed case characters fails. Therefore, the installation of SQL Server 2005 Express Edition SP1 is unsuccessful. Method 1: Change the computer name to use only uppercase characters A computer name is not case sensitive in Windows. For example, Windows recognizes "Workstation-1" and "WORKSTATION-1" as the same computer name. To change the computer name, follow these steps: Click StartCollapse this imageExpand this image, right-click Computer, and then click Properties. Under Computer name, domain, and workgroup settings, click Change settings. Collapse this imageExpand this imageIf you are prompted for an administrator password or for a confirmation, type your password, or click Continue. In the System Properties dialog box, click Change. In the Computer name box, note the original computer name, and then type a temporary computer name in uppercase characters. For example, type WORK-TMP. Click OK. Note If you are prompted to enter the name and password of a domain account that has permission to rename the computer, type your credentials, and then click OK. When you are prompted to restart the computer to apply the changes, click OK, click Close, and then click Restart Now. Follow steps 1 through 6 to change the computer name to the original computer name. When you specify the original computer name, type the name in uppercase characters. For example, type WORKSTATION-1 instead of Workstation-1. Install SQL Server 2005 Express Edition SP1. Method 2: Use a case-insensitive collation setting for the SQL Server service When you install SQL Server 2005 Express Edition SP1, do not select a case-sensitive collation setting. For more information about how to select the collation setting when you install SQL Server 2005 Express Edition SP1, see the following Microsoft SQL Server 2005 Books Online topics:
