True remote keyless entry and immobilizer systems, which let drivers access, start, and secure their cars without removing a key fob from pocket or purse, are seeing wider and wider adoption.
Logically then, expanded applications using wireless RFID technology (for low current draw on a fob's battery) are being developed to link key fobs with smart phones and other personal electronics. Future functions could then include GPS-based location of one's car in a parking lot and use of the key to pay parking fees or even retail purchases.
But for payment use, security technology is paramount, involving not only safe links but the use of crypto co-processors. Early technology demonstrations are underway by BMW, Continental
, and NXP Semiconductors
Here's a full report
on such security technology development from Dirk Wenzel and Huanyu Gu, two managers for Car Access and Immobilizers at NXP Semiconductors.
