Radio Tags – A glance into Our Future.
Feb 9th
What’s a radio id tag?
A radio frequency identification tag is a tiny tracking device with a microchip and antenna. Each tag has a unique code to identify the product, person
or animal wearing it. More than 50 million pets and 20 million livestock have already been tagged. Are humans next?
It is said that soon humans will started being implanted with radio tags so it is easy to access their medical data. These are called VeriChip. It is a medical radio identification tag that can be implanted under the skin of a patient. The chips memory holds the patients indemnification number. This enables doctors to access quickly the vital medical records of unconscious patients in the hospital emergency room. The Verichip is about the same size of a coin.
How do medical tags work?
- Chip is implanted into the arm of a human
- Handheld scanners send radio waves to the tag’s antenna to power chip.
- Powered chip sends radio frequency signals back to scanner.
- Patients number is sent fro ma scanner to a local computer
- Computer connects to main server and requests patients file.
- Server uses patient number to find file and send it to local computers in seconds allowing them to access all the medical history and information for the human.
Uses of ID chips:
- Pets – with tags on their collars, stray cats and dogs can be returned to their owners.
- Prisoners – whether in jail or out on parole, the authorities can track their movements.
- Marathon runners – runners can have their laces tagged so supporters can check locations and times.
- Medical patients – in the future, tags will store patient’s medical history as well as their patient number.
- Car Security – A chip in the car key holds the drivers number. If it matches the number in the cards memory, the card starts.

Smart Cards – The magic bankcard Chip! What does it do?
Feb 9th
Smart card is a plastic card with an embedded microchip. It can store large amounts of data, from bank details to medical records in its memory. The data is encrypted – put into code – for security.
So why a smart card? How does it protect me?
A smart card is more useful and secure than a magnetic strip card. The card can hold up to 80 times more data and is much harder to copy a chip than magnetic strip. Data is protected because it is encrypted inside the chip. Although it is not possible to steal data from the chip, the high cost and computing power required deters criminals. The memory chip requires authentication before stored data is unlocked.
The “Chip & Pin” process makes a card payments more secure. The chip in the cards holds an encrypted copy of the users four-digit personal identification number (PIN). By entering the number into a reading device, a user can prove they own the card. This has reduced instances of card fraud; without the PIN, it is almost impossible for a crimincal to steal and use another persons card.
Smart card uses
- In money – people use smart cards to access their individual bank accounts and withdraw money or check their account information.
- Telephone calls – prepaid telephone cards are credited with a number units to make calls
- Cell Phones – Smart cards in cell phones contain subscriber information to identify the user to the network.
- Computer Security – to gain access to a personal computer, a smart card can authenticate the user.
- Travel – Many subway systems use prepaid smart cards instead of tickets, passengers swipe their cards to gain access.
- Health – smart cards provide an easy and safe way of storing and checking confidential medical information.
Interesting Facts:
- The gold pad found on top of a Smart card allows a two-way flow of data between the card and the reader.
- The first smart cards were introduced in Europe during the 1990s. They were mainly used as pay-phone cards.
- Smarts cards will be replaced by radio tags embedded in objects that can be scanned remotely like key rings or even the uses body.
