Low-profile card reader

1. A low-profile card reader, comprising:

a carriage;

a single support arm, comprising:

a first end, statically mounted to the carriage;

a second end, free from the carriage;

a body connecting the first end to the second end and tapering from the second end toward the first end, wherein the body is free from the carriage, such that the support arm freely deflects along a support arm length of the support arm relative to the carriage; and

a set of strengthening channels extending along the support arm length of the support arm; and

a magnetic reading head statically connected to the second end of the support arm.

2. The low-profile card reader of claim 1 , further comprising a housing defining a card opening arranged at a non-zero angle to a longitudinal axis of the carriage, wherein the support arm is arranged with the support arm length of the support arm parallel the longitudinal axis of the carriage and the second end proximal the card opening.

3. The low-profile card reader of claim 2 , wherein:

the carriage comprises a first carriage component and a second carriage component opposing the first carriage component, the first and second carriage components cooperatively defining a card receptacle contiguous with the card opening therebetween; and

the first end of the support arm is mounted to the first carriage component with the second end proximal a card opening end of the first carriage component, wherein the card opening end of the first carriage component is proximal the card opening, and a track of the magnetic reading head arranged proximal the second carriage component.

4. The low-profile card reader of claim 3 , wherein the card receptacle is configured to encapsulate a card along an entirety of a card width.

5. The low-profile card reader of claim 4 , further comprising an IC chip reader, wherein the IC chip reader is mounted to the second carriage component proximal a card obstruction end of the second carriage component that opposes the card opening end of the first carriage component.

6. The low-profile card reader of claim 5 , further comprising a card detection pin mounted to the carriage along the card obstruction end.

7. The low-profile card reader of claim 3 , wherein the second end of the support arm protrudes beyond the card opening end of the first carriage component, wherein the second carriage component comprises an extension opposing the second end of the support arm, the extension comprising a ramp proximal the support arm.

8. The low-profile card reader of claim 2 , wherein each strengthening channel of the set comprises an opening, wherein the strengthening channels are arranged with the openings defined along a first broad face of the support arm, wherein the magnetic reading head comprises a set of tracks, wherein the magnetic reading head is mounted to the support arm with the tracks proximal the first broad face of the support arm, and wherein the support arm is mounted to the carriage with the tracks and the first broad face proximal the card opening.

9. The low-profile card reader of claim 8 , wherein the magnetic reading head is a three-track head, wherein the magnetic reading head is mounted to the support arm with a central longitudinal axis of a central track aligned with a central longitudinal axis of the support arm.

10. The low-profile card reader of claim 1 , wherein the second end defines a fork, wherein the magnetic reading head is statically mounted within the fork.

11. The low-profile card reader of claim 1 , wherein the first end of the support arm is laser welded to the carriage.

12. The low-profile card reader of claim 1 , wherein the set of strengthening channels comprise:

a central channel defined along a central longitudinal axis of the support arm, the central channel extending from the second end to the first end; and

a pair of secondary channels extending from the second end partway along the support arm length of the support arm, wherein the central channel is interposed between the pair of secondary channels.
