Abstract

A card reader includes a digital connector such as a Universal Serial Bus (USB) plug or an Apple® Lightning® plug. The digital connector includes a corresponding connector interface, which provides voltage to at least a card reader interface and an integrated circuit (IC) of the card reader. The card reader interface outputs an analog transaction information signal upon reading the card. The IC generates a digital version of the analog transaction information signal, encrypts the digital version, converts that into an analog audio signal. The audio signal can then be sent to the connector interface, which converts it into a digital signal such as a USB or Apple® Lightning® signal that is sent by the digital connector to a mobile device. Alternately, the audio signal can be sent to a microcontroller that converts the audio signal to a digital format such as USB, and then to the digital connector.

First claim

The invention claimed is:

1. A transaction object reader device having a first connector that communicates with a second connector of a mobile device, the transaction object reader device comprising:
a housing;
a transaction object reader interface that is at least partially within the housing, wherein the transaction object reader interface reads transaction information from a transaction object as a transaction information signal;
signal interface circuitry that is within the housing and that is coupled to the transaction object reader interface, wherein the signal interface circuitry processes the transaction information signal to generate a processed transaction information signal;
an interposer that is within the housing and that is coupled to the signal interface circuitry and to the first connector, wherein the interposer conveys the processed transaction information signal from the signal interface circuitry to the first connector, wherein the interposer affects a range of movement of the signal interface circuitry and the first connector relative to the housing; and
the first connector that at least partially extends from the housing and that is coupled to the interposer, wherein the first connector sends the processed transaction information signal to the second connector of the mobile device.

2. The transaction object reader device of claim 1 , wherein the interposer is anchored to the housing, and wherein the interposer limits the range of movement to affect the range of movement.

3. The transaction object reader device of claim 1 , wherein a position of the interposer relative to the housing is flexible, and wherein the interposer increases the range of movement to affect the range of movement.

4. A transaction object reader device having a first connector that communicates with a second connector of a mobile device, the transaction object reader device comprising:
a transaction object reader interface, wherein the transaction object reader interface reads transaction information from a transaction object as a transaction information signal;
signal interface circuitry that is within a housing and that is coupled to the transaction object reader interface, wherein the signal interface circuitry processes the transaction information signal to generate a processed transaction information signal;
an interposer that is within the housing and that is coupled to the signal interface circuitry and to the first connector, wherein the interposer conveys the processed transaction information signal from the signal interface circuitry to the first connector, wherein the interposer affects a range of movement of the signal interface circuitry and the first connector relative to the housing; and
the first connector that is coupled to the interposer, wherein the first connector sends the processed transaction information signal to the second connector of the mobile device.

5. The transaction object reader device of claim 4 , wherein the interposer is anchored to the housing, and wherein the interposer limits the range of movement to affect the range of movement.

6. The transaction object reader device of claim 4 , wherein a position of the interposer relative to the housing is flexible, and wherein the interposer increases the range of movement to affect the range of movement.

7. The transaction object reader device of claim 4 , wherein the interposer includes a first connector and a second connector, wherein the first connector couples a first connection point of the signal interface circuitry with a first connection point of the signal interface circuitry, and wherein the second connector couples a second connection point of the signal interface circuitry with a second connection point of the signal interface circuitry.

8. The transaction object reader device of claim 4 , wherein the interposer is configured to dissipate heat.

9. The transaction object reader device of claim 4 , wherein, to processes the transaction information signal, the signal interface circuitry generates an analog signal based on the transaction information signal and generates the processed transaction information signal based on the analog signal.

10. The transaction object reader device of claim 9 , wherein the signal interface circuitry includes a digital to analog converter (DAC) that generates the analog signal based on the transaction information signal.

11. The transaction object reader device of claim 9 , wherein the processed transaction information signal is a digital signal.

12. The transaction object reader device of claim 11 , wherein the signal interface circuitry includes an analog to digital converter (ADC) that generates the processed transaction information signal based on the analog signal.

13. The transaction object reader device of claim 4 , further comprising:
metal shielding within the housing, wherein the metal shielding protects at least one of the first connector, the signal interface circuitry, or the interposer.

14. The transaction object reader device of claim 13 , further comprising:
a neck that extends from the housing, wherein the first connector extends from the neck, wherein the metal shielding includes a first portion within the neck, wherein the metal shielding includes a second portion that is within the housing and that flares out wider than the neck.

15. The transaction object reader device of claim 13 , wherein the metal shielding is secured to the housing.

16. The transaction object reader device of claim 4 , wherein the transaction object is an element on a card, and wherein the transaction object reader interface reads the transaction information from the element on the card in response to receipt of at least the element on the card through a card slot in the housing.

17. The transaction object reader device of claim 4 , wherein the transaction object reader interface includes a near field communication (NFC) reader and the transaction object includes a NFC interface, wherein the NFC reader reads the transaction information from the NFC interface in response to the NFC interface entering into a proximity of the NFC reader.

18. A method for interfacing, the method comprising:
reading, using a transaction object reader interface, transaction information from a transaction object as a transaction information signal;
processing, using signal interface circuitry that is within a housing and that is coupled to the transaction object reader interface, the transaction information signal to generate a processed transaction information signal;
conveying, using an interposer that is within the housing and that is coupled to the signal interface circuitry and to a first connector, processed transaction information signal from the signal interface circuitry to the first connector;
