A method for managing the reading of a barcode and deactivation of an EAS tag relative to an EAS effective range and a depth of field (DoF) of the scanner is described. A product may comprise a barcode and a co-located EAS tag. The method uses a distance sensing system to sense how far the product is located from the scanner front window. The method only outputs the decoded data of the barcode when the product is inside an EAS effective distance. When the product is inside the EAs effective distance, the EAS tag on the product is deactivated. When a customer leaves a store with the EAS tag deactivated, a store alarm may not sound. When the product is outside of the EAS effective distance, but inside the DoF, the decoded data of the barcode is discarded. 1. A method , comprising:reading a barcode with a scanner having a depth of field (DoF);determining, with a distance sensing system, a distance between the scanner and the EAS tag;if the distance from the scanner to the EAS tag is less than an EAS range, outputting barcode data to a host, sending a signal to an EAS device to deactivate the EAS tag, and provide a positive indication to a user; andif the distance from the scanner to the barcode is greater than the EAS range, discarding the barcode data and providing a negative indication to the user;wherein the host and the EAS device are coupled to the scanner.2. The method according to claim 1 , comprising sending claim 1 , via the scanner claim 1 , a status message to a user based on information received from the EAS device and scanner.3. The method according to claim 1 , wherein claim 1 , the distance sensing system uses infrared (IR) wireless technology.4. The method according to claim 2 , wherein claim 2 , the status message is an audible message.5. The method according to claim 2 , wherein claim 2 , the status message is a visual message.6. The method according to claim 1 , wherein claim 1 , an EAS system comprising the EAS device and the scanner is based on ...
