In some examples, a wireless card reader detects insertion of a chip card at a chip card reader interface that includes electrical contacts positioned in the wireless card reader to contact contacts of the chip card when inserted into the wireless card reader. The wireless card reader may send, to a mobile computing device, a wireless communication request to send a PIN to the card reader. The card reader may receive, from the mobile computing device, a wireless communication including the PIN entered by a user on the mobile computing device. The card reader may send the PIN for authentication of the PIN. The card reader may receive a confirmation that the PIN has been authenticated. The card reader may send, to the mobile computing device, via the communication component, an indication of the confirmation that the PIN has been authenticated.

Secure wireless card reader

A card reader configured to read a smart card can be detachably connected to a mobile computing device. When the card reader is attached to the mobile device, an application installed on the mobile computing device permits the mobile device to communicate with the card reader in order to process transactions. Security measures can be used on the mobile device to prevent theft of a PIN during software PIN entry of a payment transaction. The mobile device can prevent the keypad or other input interface from displaying feedback. The mobile device can also prevent passcodes from being stolen by displaying media encoded with digital rights management (DRM) and by managing the media and user inputs at a secure server. A mobile device can securely communicate with a card reader for a payment transaction using asymmetric or symmetric encryption.

Software PIN entry

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing a plurality of stored fingerprints, wherein each of the stored fingerprints is associated with a respective software environment and a respective mobile device; receiving from a first mobile device a first fingerprint of a first software environment in the first mobile device; determining whether the stored fingerprints include less than a threshold amount of fingerprints identical to the first fingerprint; based on a determination that the stored fingerprints include less than the threshold amount of fingerprints identical to the first fingerprint, determining that the first software environment is a compromised software environment; and performing a corrective measure.

Hierarchical data security measures for a mobile device

A method includes receiving a request for a list of nearby user devices, where the list of nearby user devices will be sent to a merchant device, where the merchant device is associated with a merchant, where the merchant operates a plurality of merchant devices, and where the merchant device is included in the plurality of merchant devices; receiving a respective location for one or more user devices, where each user device is associated with the merchant; determining, for each of the one or more user devices, whether the user device is nearby the merchant device, based on the respective location, to the merchant device than the other merchant devices in the plurality of merchant devices; generating the list of nearby user devices based at least on the determination; and sending the list of nearby user devices to the merchant device.

Software pin entry

Several embodiments include a mobile device that uses a media file to render a passcode entry interface. The passcode entry interface can have an assigned location of an input element that corresponds to an inputtable value in the passcode entry interface. The media file can include a visual depiction having the input element at the assigned location. In several embodiments, the media file does not store the association between the assigned location and the inputtable value. The assigned location corresponding to the inputtable value can be separately stored. The mobile device can receive a coordinate of a touch event on the passcode entry interface. To determine a passcode entry based on the touch event, the coordinate can be compared against the separately stored assigned location to determine a corresponding input value to the coordinate.

A method of includes receiving hotspot identification data from the first device, where the identification data identifies a plurality of WiFi hotspots that are in proximity to the first device; determining that the second device is associated with the first device; sending the hotspot identification data to the second device, where the first device and second device are mobile devices; receiving an indication of proximity from the second device; and notifying the first device of the indication of proximity.

Detecting proximity using WiFi hotspots

A method of detecting location includes receiving, on a mobile device, a plurality of previously stored WiFi hotspots; detecting, on the mobile device, a plurality of surrounding WiFi hotspots; comparing the plurality of surrounding WiFi hotspots to determine one or more differences between the plurality of previously stored WiFi hotspots; determining the differences satisfy a difference threshold; sending the plurality of surrounding WiFi hotspots to a location lookup system; and receiving a response from the location lookup system.

Detecting location using WiFi hotspots

Method, systems, and apparatus for receiving the email message from a sender device; identifying, using data processing apparatus of a payment service system, a sender email address, a service email address, and one or more recipient email addresses from the email message; identifying, for the sender email address, a sender financial account associated with the payment service system and, for each of the one or more recipient email addresses, a respective recipient financial account associated with the payment service system; identifying a payment amount from a subject or body of the email message; submitting a request to transfer, using the payment service system, the payment amount from the respective sender financial account to the respective recipient financial account.
