TRANSACTION FACILITATION METHODS AND APPARATUSES

Devices and systems using Bluetooth Low Energy (BLE) to facilitate sale transactions are disclosed. The devices can be in the form of a credit card, debit card, smart phone, wearable device such as a watch or glasses. A virtual payment card can store information relevant to a plurality of preexisting accounts and can provide outputs that include wirelessly communicating account information to a wireless device such as the emulation device, programming a dynamically alterable magnetic strip to include magnetized sectors that are magnetized in a fashion that reflects account information, and a visual output of the transaction card whose relevant card information has been communicated wirelessly or to the magnetic strip. Bluetooth-enabled electronic devices are configured to alternately scan and operate as beacons and employ various technologies to detect the signal strengths of other Bluetooth devices, and such signal strength values are wirelessly communicated to a server that resolves the various signal strength values into relative locations of each of the Bluetooth electronic devices. The electronic device that has the closest proximity to the emulation device is instructed to communicate information regarding a preexisting account to the emulation device. A proximity detection apparatus employs an RF transceiver and a pair of antennas at two spaced locations that are located at different distances from each of a plurality of signal sources. The signal source whose signal strengths detected at the two locations are of the greatest difference in magnitude is the relatively closest signal source. La présente invention concerne des dispositifs et des systèmes qui utilisent Bluetooth Low Energy (BLE) pour faciliter des transactions de vente. Les dispositifs peuvent se présenter sous la forme d'une carte de crédit, d'une carte de débit, d'un téléphone intelligent, d'un dispositif portatif tel qu'une montre ou des lunettes. Une carte de paiement virtuel peut stocker des informations pertinentes à une pluralité de compte préexistants et peut fournir des sorties qui comprennent la communication sans fil d'informations de compte à un dispositif sans fil tel que le dispositif d'émulation, la programmation d'une bande magnétique dynamiquement modifiable pour comprendre des secteurs magnétisés qui sont magnétisés d'une manière qui reflète des informations de compte, et une sortie visuelle de la carte de transaction dont des informations de carte pertinentes ont été
