Abstract
Systems and methods for reading from a transaction instrument are disclosed. In some examples, a system receives a signal from a reader interface in response to an interaction between the reader interface and the transaction instrument. The system amplifies the signal using an amplifier and based on a gain of the amplifier to generate an amplified signal. In some examples, the system converts the amplified signal. The system decodes data from the amplified signal. The system adjusts the gain of the amplifier based on the data. The system outputs the data, in some cases in an encrypted form.
Claims20
A method of reading from a transaction instrument, the method comprising:
- receiving a signal from a reader interface in response to an interaction between the reader interface and the transaction instrument;
- amplifying the signal using an amplifier and based on a gain of the amplifier to generate an amplified signal;
- converting the amplified signal to decode data from the amplified signal;
- adjusting the gain of the amplifier based on the data decoded from the amplified signal;
- encrypting the data to generate encrypted data;
- and
- outputting the encrypted data.
A method comprising:
- amplifying a signal using an amplifier and based on a gain of the amplifier to generate an amplified signal, wherein the signal is based on an interaction between a reader interface and a transaction instrument;
- decoding data from the amplified signal;
- adjusting the gain of the amplifier based on the data decoded from the amplified signal;
- and
- outputting the data.
A system comprising:
- an amplifier that receives a signal from a reader interface in response to an interaction between the reader interface and a transaction instrument, wherein the amplifier amplifies the signal based on a gain of the amplifier to generate an amplified signal;
- an integrated circuit (IC), wherein the IC decodes data from the amplified signal, wherein the IC adjusts the gain of the amplifier based on the data decoded from the amplified signal, and wherein the IC encrypts the data to generate encrypted data;
- and
- an output interface that outputs the data.
