Detectan falla en tarjetas de Metro

Detectan falla en tarjetas de Metro 

 

Las fallas que han estado sucediendo en las tarjetas del metro , son debido a la interconexion, que estan realizando entre sistemas para poder hacer , uso en mtrobus y en metro ,   ya que los cargos se estan realizando , pero al realizar la operacion y bajar el credito en la BD ,   al actulizarze entre sistemas, se bloquean las operaciones y al encontrar un error , automaticamente se bloquea la tarjeta o almenos su numero de serie .

Por eso es lo de las historias , de que pasa una persona y que si se la da a otra , ya no le funciona, alcabo de un segundo de haberla usado ....

RFID Blocking Wallet

Cartera para proteger de ser scaneado RFid

 Cada vez es mas comun debido al hueco de seguridad y la facilidad de scanear remotamente que haya mas productos de este tipo ,  es buena opcion para porteger tus datos y tarjetas ,

More comfortable than aluminum foil in your pants.

There's some seriously scary stuff out there in the world -- from bird flu and terrorism to depleting our planet of natural resources. There's not a lot that the average person can do about much of the things that may keep us up at night. Luckily, there's one scary prospect on the horizon that we can help with -- and it doesn't require lining your pants with aluminum foil! Aren't you lucky?
Imagine if you will, some of these possible real-life scenarios:
A shadowy character crouches unseen in the bushes. He doesn't have a gun or a knife, but he has a laptop. He watches as his prey walks by. Invisible radio waves emitting from the credit-card in his wallet get picked up by the laptop, recorded, and saved onto a cloned card. For all intents and purposes, this man becomes you, and has decided to go shopping.
Or maybe he picked up the passkey that lets you into your office building. With ease, he can now walk into your secure office building and steal your company's equipment. The next morning, security guards are waiting in your cube to have a chat.
The nightmare scenario was brought forth recently - a bomb lies waiting in a garbage can. Sensitive electronics read the identification cards and passports of the people who walk by, waiting until somebody of your nationality comes close...
It's a scary world out there. Credit card companies and governments are putting RFID chips in your cards and identification, sometimes without your knowledge. Protect yourself and your money with a wallet that specifically inhibits those radio frequencies from escaping until you pull your card out. Did we mention you don't need to put foil in your pants? It's important to us that you know that you do NOT have to put foil in your pants. Very important. No foil. In your pants... none... zip... nada.
The DIFRwearR RFID Blocking Wallet is a high-quality leather billfold with a built in Faraday cage to block RFID transmissions. It has room for six credit cards, your cash, business cards and your ID. Don't get caught unprotected.
