STMicroelectronics RFID ( ISO 14443 B Type) Technology  

•          Higher security level – Anti clone technology : means that the card ID’s are unique and can not be duplicated. This is guaranteed from the chip manufacturer, so hacking is not possible

•          Unlike other technologies, no known duplicates of these cards are available in the market

•          Higher data rate (speed of communication) and Faster transaction

•          Easy to meet Global standards

•          Is safe upto 70 degree centigrade.

•          Works well under noisy environments

•          Unique ID’s which can not be copied

•          Future proofed technology

–         Data transmission speeds will be increased in subsequent developments

Special technology features for further integration

 

OEM Machine - Smart card solution to activate a high cost machine at customers end, where by the machine will only be activated or de activated based on time or the number of runs. (somewhat a similar concept used in prepaid solutions)

 

Special hardware password, where high degree of security is required at a low price, and volumes are high. A hardware based hack proof system, which obviates the needs of sophisticated software to control.

 

Hardware enabled backward counting, wherein the value will always go down, and never go up. Can be securely used in payment applications. High values can be stored

 

Special Boolean logics, to control various logical parameters, without going into software or firmware complexity.

 

Other Advantages and technology comparisons

 

A latest design, working directly with a Chip manufacturer and design house

 

Long term approach, brings in strategic advantage – Future product up gradations will be at a fraction of cost  - our upgrades will keep the product from becoming obsolete at fraction of a cost of a similar new products….like our connectivity solutions developed  under development will be integrated in the existing modules at very reasonable costs.

 

The card duplicates as a photo ID card, which is an instant human identification, difficult to carry other person’s identity.

 

Technology vis a vis Biometrics –

 

Zero rejections unlike Biometrics (Finger based), which depends on probability matching. The problems are more acute as the temperatures go down. Also the technology fails to address clearly with one percent of all population. This problem leaves users of this technology with stressful administrative hurdles.

 

Cannot be duplicated in any way, again unlike biometrics where high tech frauds are still possible, as leaving a fingerprint on a glass can make your identity theft vulnerable.

 

Technology vis a vis long Distance Technologies (Current technology bottlenecks, companies all over the world working to tackle these issues) –

 

Active Tags –

Because distance is high, lots of invalid data is entered.

It is not easy to limit the technology to a particular distance as distance will change because of change in environment conditions. This will lead to lots of administrative problems.

Cost of one Tag will be around Rs 600 to Rs 1000/-.

 

Passive Tags –

The cost of readers is very high

20% failure rate, to record the transactions.

Also, the actual distance at present is not what is under test conditions. In some cases, there is a default of more than 70 to 80%, what we have tested.

 

Constraints of Contact Cards (Non-RFID Technology)

Limited transaction speed makes contact technology unsuitable for high transaction volumes/throughput.

Physical contact between cards and readers reduces the lifetime of the cards and readers.

Tagging and identification are not possible because of contact constraints.

Disposable contact based smart tickets are not available in the market.

The cards are not robust for intensive usage.

 

Benefits of Contact-Less Cards (RFID Technology)

Very high transaction speed to address high mass transit applications.

Cheaper infrastructure.

Lower maintenance.

Superior ability to prevent frauds.

Ability to personalize and add new services
