Abstract: A system for provisioning credentials onto an electronic device is provided. The system may include a payment network subsystem, a service provider subsystem, a primary user device, and a secondary user device. The user may select a particular payment card to provision onto the secondary user device by providing an input at the primary user device. A broker module running on the service provider subsystem may then transfer a disabled pass to the secondary user device. Concurrently, the payment network subsystem may direct a trusted service manager module on the service provider subsystem to write credential information onto a secure element within the secondary user device. Once the secure element has been updated, the broker module may provide an activated pass to the secondary user device so that the secondary user device can be used to perform NFC-based financial transactions at a merchant terminal.

Abstract: A magnetic stripe decoder includes an amplitude discrimination circuit to remove noise due to glitches. The use of amplitude discrimination rather than a filter, which is in common use today, permits a single decoder circuit to decode data over a wide range of frequencies including the standards 75 BPI and 210 BPI. In the absence of such an amplitude discriminator, two different decoders, one for 75 BPI and one for 210 BPI are necessary.
