What is Read-a-Card?

Read-a-Card is a software tool which allows users to easily view a contactless smartcard's unique ID and automatically insert it into text input fields on other applications, helping with the easy integration of RFID technology into new or existing systems. This is sometimes known as a keyboard 'wedge' and replaces similar functions of barcode scanners.

This ability provides obvious integration opportunities in both hardware and software development and is made even more versatile by the capability to set the card ID format you want Read-a-Card to use. The software also allows for the recording of time stamps when a card is presented offering opportunities for event logging in applications such as time recording and access functions.

What information does Read-a-Card allow me to obtain?

Read-a-Card allows the user to obtain the unique ID from many types of contactless cards and tags. By default it is set to copy the card ID to the keyboard buffer when the program is minimised, but this feature can be turned off. You can also set the card ID format you want Read-a-Card to use. This can be Hex Standard, Hex Reversed, Decimal Standard (4 byte), Decimal Reversed (4 byte) or iClass Wiegand (26 bit or 37 bit).

Which readers and cards are compatible with Read-a-Card?
