Card reader for mobile device
View Patent ↗A card reader for use with a mobile device includes a rotatable face that can be rotated over a portion of the mobile device so that when the user slides a card through the card reader, the overlapping portion of the rotatable face prevents the card reader from spinning or rotating. A foot and/or a housing for a jack on the bottom of the card reader prevents the card reader from accidently turning off the mobile device during use.
1. A card reader comprising:
a stationary back plate;
a stationary front plate connected to the back plate, wherein a slot is formed between the back plate and the stationary front plate and wherein the slot is configured to receive a card;
a protrusion extending from a first bottom portion of the stationary back plate or the stationary front plate, wherein the protrusion extends at least a height of an on/off button of a mobile device, abuts against a surface on which the on/off button extends from on the mobile device when the card reader is inserted into the mobile device, and does not overlap the on/off button when the card reader is inserted into the mobile device;
a jack extending from a second bottom portion of the stationary back plate or the stationary front plate apart from the first bottom portion; and
a housing extending from the second bottom portion of the stationary back plate or the stationary front plate, wherein the jack extends through the housing.
2. The card reader of claim 1 , further comprising a rotatable front plate rotatably coupled to the stationary front plate and rotatable along a face of the stationary front plate parallel to a front or back face of the mobile device, wherein the rotatable front plate is rotatable to be positioned such that at least a portion of the rotatable front plate overlaps a surface of the mobile device when the card reader is inserted into the mobile device.
3. The card reader of claim 2 , wherein the stationary back plate, the stationary front plate, and the rotatable front plate are triangular.
4. The card reader of claim 3 , wherein the stationary back plate is a larger triangle than the stationary front plate and the rotatable front plate.
5. The card reader of claim 4 , wherein the stationary front plate and the rotatable front plate have the same triangular surface area.
6. The card reader of claim 1 , wherein the stationary back plate and the stationary front plate form a unitary structure.
7. The card reader of claim 1 , further comprising a jack extending from a bottom portion of the stationary back plate or the stationary front plate.
8. The card reader of claim 7 , further comprising a housing extending from the bottom portion of the stationary back plate or the stationary front plate, wherein the jack extends through the housing.
9. The card reader of claim 1 , wherein the card is a magnetic strip card.
10. The card reader of claim 1 , further comprising a read head along a portion of the stationary front plate or the stationary back plate.
11. A card reader for a mobile device, comprising:
a stationary first plate;
a stationary second plate connected to the first plate, wherein a slot is formed between the first plate and the second plate and wherein the slot is configured to receive a card;
a protrusion extending from a first bottom portion of the stationary first or second plate, wherein the protrusion extends at least a height of an on/off button of a mobile device, abuts against a surface on which the on/off button extends from on the mobile device when the card reader is inserted into the mobile device, and does not overlap the on/off button when the card reader is inserted into the mobile device; and
a jack extending from a second bottom portion of the first or second plate apart from the first bottom portion.
12. The card reader of claim 11 , further comprising a third plate rotatably coupled to the second plate and rotatable along a face of the stationary first or second plate parallel to a front or back face of the mobile device, wherein the third plate is rotatable to be positioned such that at least a portion of the third plate overlaps a surface of the mobile device when the card reader is inserted into the mobile device.
13. The card reader of claim 12 , wherein the first, second, and third plates are triangular.
14. The card reader of claim 13 , wherein the stationary first plate is a triangular back plate larger than the second and third plates.
15. The card reader of claim 14 , wherein the second and third plate have the same triangular surface area.
16. The card reader of claim 11 , wherein the stationary first and second plates form a unitary structure.
17. The card reader of claim 11 , further comprising a housing extending from the bottom portion of the first or second plate, wherein the jack extends through the housing.
18. The card reader of claim 11 , wherein the card is a magnetic strip card.
19. The card reader of claim 18 , further comprising a read head along a portion of the stationary first plate.
