Encoding data in multiple formats |
摘要 |
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for modulating card information between a card reader and a user device. One of the methods includes receiving, from a read head of the card reader, card information associated with a card. The card information is encoded in a first format to be sent to the user device at a first data rate. The card information is encoded in a second format to be sent to the user device at a second data rate lower than the first data rate. The card information is sent to the user device encoded in the first format and the second format. |

1. A computer-implemented method comprising:
receiving, from a payment object reader, information associated with a payment object; encoding the information associated with the payment object into a data segment of a first packet; generating a preamble segment for the first packet; encoding the information associated with the payment object into the data segment of a second packet to be sent to a user device; modulating the first packet and the second packet into a signal that includes at least a first portion that corresponds to the first packet and at least a second portion that corresponds to the second packet; and sending, to the user device, the signal including the first portion that corresponds to the first packet and the second portion that corresponds to the second packet. |
