Proximity read smart cards are uniquely factory encoded and cannot be duplicated

Fears of job losses have been played down at a major steel company which has stopped production at its works for one week. The firm Tata said it had to realign capacity with demand, hence the production halt at Llanelli in Wales. The industry is usually an indicator for the wider economy. “We have been weathering a prolonged storm,” a Tata spokesman commented, adding: "We are very concerned about the bottom line. The indicators are very worrying indeed.”

Contactless smart cards which offer the fastest throughput available are used to operate Tensor’s time and attendance, access control and visitor monitoring systems. All Tensor proximity read smart cards and key fobs use the same reliable RF (Radio Frequency) reading technology. Each smart card reader transmits a 125 KHz frequency field (the electromagnetic field), which is picked up by an aerial in the smart card. The smart card microchip is a passive device which holds a unique factory encoded ID number that cannot be duplicated, making it very secure indeed.
