If you are disabled or pushing a baby carriage you know just how dificult it is to reach the button on the automatic door openers and they never stay open long enough. All baby carriages, wheelchairs, crutches etc should contain RFID chips so as you approach the door the RFID door opener opens the door.

RFID (radio frequency identification) chips are low cost <7 cents to manufacture and can be applied using a simple sticket on a wheel chair, crutches etc. The alternative would be an expensive bluetooth, infrared or other wireless solution. |
|
| |
So, if I can record and simulate your RFID chip, I can open your car? |
|

The encryption capabilaties of RFID are getting better. You use RFID to pay for items electronically today such as Gas at your local petrol station. Several cars already have an RFID reader that is used to start the vehicle providing added security over traditional keys. |
|
| |
OK yes you could break the current 128 bit RFID security in approximatly 1 hour using multiple computers Google break RFID encryption but really I was just thinking about automating the disabled door button at the local shop that anyone could press. |
|
| |
I think if you had a standard keyfob that the chair/pram/whatever user could use to open doors then this could work. But the idea that a door opens automatically when a chair/pram/etc is in its vicinity suggests the possibility of false activations. |
|
| |
If the system will avoid false activations by determining through sheer proximity that a person must want to use the door, then why not just use the proximity detection system that most supermarket doors use already? The issue of the user being disabled/burdened with pram becomes irrelevant. |

Good design and timing of the automatic door opening buttons can eliminate the need entirely. Many installed today are similar to the following: button about 15cm square, easily visible, placed approx 80cm off the ground and 2-3 metres before the door. For places where that can't be done , I feel that the idea has some merit in keyfob form. [+/-] |

Yes, the RFID tag is ~7¢ but the reader is quite pricey. |

About $500 a door should cover it. For a shopping mall or public building I would assume would be an insignificant amount. |
|
| |
Why would those require authentication before opening their doors? I thought you were talking about cars. |
|
| |
Sorry you don't really require authentication to open the door I was just responding to your request in relation to security. I assume that we would want some level of validation because you really don't want people sticking an RFID sticky label that can open an automatic rfid enabled door on the actual doors. |

They would never close :-) |
