For certain applications (e.g., inventory) the devices are used only once a year for a few days. If a device is not used for an extended period of time, appropriate precautions should be taken. The battery should be fully charged before storage and then removed from the device. The battery must be recharged after 12 months at the latest, as it will discharge itself during the rest period. Within three months, depending on the temperature, up to 80% of the charge will be lost. At high temperatures, the discharge is correspondingly faster. The ideal temperatures for an unused battery are between 15° C and 30° C. Large temperature fluctuations are generally detrimental to batteries and should be avoided.

If this barcode type is set and no further check is carried out (neither by the scanner nor by the application), a very high error rate must be expected. The following measures should be taken:

• If possible, use a check digit.
• Use a length fixation. That means, only barcodes with one or two lengths are accepted by the scanner.
• If there is a constant number of digits within the code, it should be checked by the application.

When a LogiScan-600/800/1100 with RFID module is delivered, all transponder types are normally activated. If the transponder types in the RFID module are set by the application, a manual setting is not possible or will be overwritten by the next start of the application. If the transponder types are not set by the application, a manual configuration can be made as follows:

• Connect the LogiScan-600/800/1100 to the desired COM port of the PC.
• Call up the system menu on the LogiScan-600/800/1100 (see corresponding FAQ),
• Call the Admin→System menu function and press SHIFT 9,
• Select "RF-ID Port" and press ENTER,
• Com0 (this is the normal RS-232 interface, which is also used for data transmission) and press ENTER.
• Start the ACG Utility on the PC (can be downloaded from the product page).
• Select and connect the appropriate COM port.
• In the "Operation Mode" field, the desired transponder types can be activated / deactivated.
• Clicking the button "Apply Settings" writes the settings to the RFID module.
• Afterwards, the ACG Utility can be terminated and the application can be started on the LogiScan-600/800/1100.

The operating frequencies 125/134 kHz and 13.56 MHz are suitable for applications with low reading distances. If the transponder is only to be used for identification, a read-only transponder suffices. If data is to be stored in the transponder, a read-write transponder is necessary. The 125/134 kHz technique (LF) still distinguishes between read-only (read-only) and read-write transponders (chip has an additional data memory). This is historically, since the RFID development started with LF technology and these read-only chips were cheaper. At all other operating frequencies, there are now mostly read / write transponders.

The 125 kHz technique allows mobile devices to read distances up to 10 cm (depending on antenna and tag size.) Even if the transponder tags are attached to metal or embedded in it, automatic identification is possible Are, among other things, production control, object/goods identification in the metal environment, access control and animal identification.

13.56 MHz transponders enable the simultaneous reading of several transponders with their anti-collision technology. The range with mobile devices is however shorter than at 125/134 kHz and is max. Few centimeters. Areas of application are, inter alia, Production control, object/goods identification, access control, ticketing (e.g. public transport, events).

868-MHz tags (UHF) offer a high reading range of up to 10 meters, but the carrier material on which the tags are attached, as well as the contents of the packaging, have a great influence on the range. Areas of application are, inter alia, Production control with read distances greater than 2 meters, logistics, material flow (pallets etc.), object/goods identification (reusable and transport packaging).
