The bar code is based on a binary concept and is the optical translation of a numeric or alphanumeric code in a set of high contrast graphic elements. These elements (alternating vertical bars and white spaces) are arranged so that they can be read and decoded by a scanning sensor. The background under the bar code must therefore always be white to allow perfect reading with laser guns or scanners.
Our Barcodes contactor or CCD scanner comes with a durable, easy-to-use, and is an entry-level and economical product For users looking for simple, ecomic solutions, easy to install via USB connectivity, no driver from Installing, keyboard emulation reading, so easy to interface with software applications.

One Button with LEDs and Beep Indicators, Competitive price is offered to promote and strengthen the competitiveness of businesses. Our product is making it very useful for retailer retailers to benefit from the power of barcode technology. Optimal for reading fidelity cards.
They are the latest generation tiles with very thin antennas inside the tiles, are recognized remotely by dedicated radio receivers. The rfid cards can be high or low frequency; These are passive transponders without electric charge, solicited to pass in front of the magnetic reader. The player emits a radio signal that activates the microchip and provides the energy needed to respond with the information stored in the chip. They are low frequency chamfers (125Khz) EM-4200 read-only, 128-bit memory capacity. They are low frequency read and write T5577, 330-bit memory capacity. RFID cards are very much used as access control cards (badges, cards, cards, etc.) and recognition, and in general for all situations where a pass is needed (eg ski pass, fan card). They are also used for the opening of locks (hotel industry) such as non-bank electronic pens (eg holiday villages, nightclubs, etc.), transport (tram / bus / train subscriptions, etc.) for electronic ticketing. These cards store data by accessing remote devices, thanks to electronic devices inside the card: tag or transponder. The tag consists of a chip and an antenna; The chip is the memory that contains a unique code, which is transmitted through the antenna to the reader's partition, which will control the received data at extremely low times. The card tag may be active or passive depending on whether it is powered by an internal battery, then there may be high and low frequency tags, UHF, etc.
