The present invention relates to consumer electronics and more specifically to a system for activation of an electronic component at a point of sale terminal.
Radio-frequency identification (RFID) technology is being implemented at many large retail establishments at the case and pallet level. Pilot implementation of RFID tagging for individual items has started. It is likely that widespread item-level RFID tagging will follow. A significant problem for retailers has always been inventory shrinkage due to theft or loss of items, which can exceed one percent of total sales revenue. For large retailers, this shrinkage can translate into millions, and for some billions, of dollars. High shrinkage areas within the business include the areas of electronics devices, small home appliances, and multimedia (CD, electronic games, and DVD players). These are high value, high margin products, which are easily concealed, lending to a very high internal as well as external theft rate. Many factors play into high shrinkage, such as poor inventory management, poor hiring and training choices, as well as poor operational practices at the store level. These operational issues lead to excessive product turnover rates, poor customer services with stock outages, all leading to lost sales and lower margins. Depending on the inventory agreement between the retailer and supplier, the financial impact can apply to both. In the end, it is the honest consumer that pays for the incremental cost of inventory shrinkage.
There is a need for a solution to limit the theft or shrinkage of items. RFID tagging of the item level product may help if the RFID tags are used for both checkout and as anti-theft devices. If used as anti-theft RFID tagged items would be scanned at doorways. Tags for which an anti-theft bit had not been deactivated would trigger an alarm. However, RFID as an anti-theft technology may be defeated by various means including the use of metal shielding, or the removal, destruction, or substitution of the tags. Employees may also remove items through doorways that are not equipped with anti-theft scanners or readers. Traditional electric or magnetic ant-theft tags have the same deficiencies. Thus there is a need to employ an improved anti-theft method.
According to one embodiment of the invention, wireless activation technology is imbedded in an item by the supplier, and enabled by the retailer at the point of sale. This solution is applicable to products such as iPod and other MP3 devices, video game modules, electronic toys, cell phones, and portable DVD players, or any electric or electronic device.
It is the aim of this invention to provide a method and system of wireless activation technology, such that an electric or electronic device is activated only when a password for activation is supplied by wireless means at the point-of-sale.
It is further the aim of the invention to provide a means for generating a password that combines elements from different tagging means, e.g., RFID tags and barcodes to make decryption of the password more difficult.
It is also the aim of this invention to provide a method for the mutual authentication of labels applied to retail items.
As RFID becomes more popular suppliers will implement an RFID or other wireless sensor as part of their item level product. Once the items came into the store via case or pallet, the bulk items would be broken down into the item level.

The computing system 110 is used to control a point-of-sale terminal (POS) 155, and a reader or communications device 150 for reading and communicating with a circuit containing a wireless activation device 109. The reader devices 109, or device reader, may communicate with the point-of-sale terminal 155 and computing system 110 by wired or wireless means such as WiFi, 801.11x, or Bluetooth.
The reader 150 and wireless activation device 109 may form a system that uses RFID for communications, or other wireless communications systems 175 such as Bluetooth, Zigbee, or WiFi. The electronics item 107 may be manufactured with the functioning of the power supply or other critical component such as the display screen or speakers are in a disabled state. The wireless activation device 109, e.g. RFID tag, or Bluetooth, Zigbee, WiFi communication devices, upon receipt of a password protected command may be used to initiate a switching circuit to enable an activation circuit to enable the working of the power supply or other circuit of the electronic item 107. The password-protected instruction conveyed by wireless communication 175 to the wireless activation device 175 may permanently change the state of an activation circuit from off to on. Thus, the electronics item may be enabled at a Point of Sale 155. Additionally, the point-of-sale or local computing system may be used to store and manage the passwords used to enable the activation device. The wireless activation device may be an RFID circuit which also contains product information, e.g. an EPCglobal electronic product code. The product information may be recorded at the same time that the activation is accomplished.
Retailers will be able to identify the need for a specific product on the shelf. The system makes the needed recommendations of the correct number of units to be placed on the shelf. This number is derived on sell through information gained from the stores sales processors. As each product is tracked through the register the RFID tag may be scanned or read at the point of sale and the sales data is then moved into the store's order database triggering a re-order process.
Unlike previous wireless locking and unlocking systems, in one embodiment of this system 100 the activation may be performed once and is permanent. In a preferred embodiment, shrinkage, or theft, may be reduced by the inclusion of a wireless device 109 to enable the working of a consumer electronic item 107, such as small home appliances, multimedia, CD, electronic game, electric razor, DVD players, stereo, MP3 player, computer, PDA, and TV. The electronic item 107 may be manufactured with the functioning of the power supply or other critical component such as the display screen or speakers in a disabled state. The wireless device 109, e.g. RFID tag, Bluetooth, Zigbee, WiFi, and the like, upon receipt of a pass-word protected command is used to initiate a switching circuit to enable the working of the power supply of the electronic item 107. The electronic item 107 may be enabled at the Point of Sale 155.
Thus, the scanning operation may be used to determine the authenticity of the bar code number and the RFID tag number. These numbers may be compared in the computing system to determine whether the numbers are consistent, e.g. that at least one of the tags has not been switched with another one.
