     DETAILED DESCRIPTION 
     In certain embodiments of the present invention, an electronic tag and/or electronic device can be configured such that the electronic device selectively receives, stores or uses data from the electronic tag in conditions corresponding to a physical disturbance of the electronic tag (e.g., a ripping, tearing or partial separation of the tag). For example, the electronic tag (e.g., powered via electric and/or magnetic fields from a nearby electronic device) can be configured to detect a physical disturbance, by, e.g., determining whether a particular portion of an antenna is connected to a chip in the tag, determining whether a chip in the tag is connected to a particular pin (or particular number of pins) in the tag, determining whether an above-threshold vibration has been sensed, or determining whether a first antenna in the tag senses a signal from a second antenna in the tag. Upon detecting the physical disturbance, the electronic tag can transmit a signal to a nearby electronic device that includes particular data to the electronic device. As another example, an electronic tag can repeatedly transmit data to a nearby electronic device. However, a physical disruption of the tag can inhibit or stop the transmission or can change a characteristic of the transmission. The nearby electronic device can condition storage and/or use of the data on detection of a change in a tag signal (e.g., an abrupt stop in a tag signal or an change in a power of a tag signal exceeding a negative threshold). 
     In some instances, the electronic tag can be configured to be or include a sticker. The electronic tag can then be positioned on a container of a product, such as a box containing a fast-food item, a lid on a cup containing a drink, a package containing a toy, and so on. In some instances, the electronic tag can be configured to be party of a container (e.g., part of a take-out bag, food box, toy package, etc.). For example, a container can include a perforation line with the electronic tag straddling at least a portion the line so as to promote a physical disruption of the tag upon opening the container. 
     The data can include information pertaining to a contained object. For example,  FIG. 1A  illustrates an example an electronic tag transmitting data about a food item to an electronic device according to an embodiment of the invention. In the illustrated example, an electronic tag is provided as part of a seal  105  that is positioned on a food container  110 . In the depicted instance, food container  110  is a box that contains a sandwich food item  115 , and seal  105  is positioned along an opening of food container  110  to inhibit opening of the container. Disturbance of seal  105  (e.g., by ripping it) is nonetheless possible, which may also disturb the electronic tag. Disturbance of the electronic tag facilitates or triggers transmission of data from the tag to an electronic device  120 , which can include a wearable device worn by a user  125 . The data can include nutritional information (e.g., a quantity of calories, fat, salt, sugar or protein) pertaining to food item  115 . In some instances, the nutritional information encoded in and transmitted by the tag particularly pertains to food item  115 , such that it reflects any customizations of an order and/or such that it does not include nutritional information pertaining to other food items (e.g., non-ordered menu items). 
       FIG. 1B  illustrates one example of a data transmission from an electronic tag  130  (e.g. included in seal  105 ) to an electronic device  120  according to an embodiment of the invention. In some instances, electronic device  120  can scan for electronic tags by repeatedly (e.g., at least 1, 5 or 20 times per second) transmitting electrical and/or magnetic fields via an antenna (e.g., a radio frequency identification (RFID) antenna). When electronic tag  130  is sufficiently proximate to electronic device  120  to receive the fields, electronic tag  130  can use the energy to power up tag  130 , such that it can retrieve and transmit the encoded data to electronic device  120  via an antenna (e.g., an RFID antenna), such as a physical disturbance of tag  130 . 
     Upon receiving the data, electronic device  120  can generate and present a presentation that identifies nutrition variables in the data. For example, in the depicted instance, electronic device  120  can present a calorie count for each item and for the order. Electronic device  120  can further use the data to update one or more cumulative nutrition variables, which can also be presented. 
     It will be appreciated that the example of  FIGS. 1A-1B  is illustrative, and that various modifications are contemplated. In some instances, an electronic tag can accompany a different type of package or container and/or can transmit different types of data. For example, an electronic tag can be included as part of a bag or a seal including the tag can be positioned on a bag, and the data can include nutritional information for particular food items to be included in the bag. As another example, an electronic tag can be adhered onto on a toy or toy packaging, and the data can include information about the toy (e.g., instructions or an app customization). As yet another example, an electronic tag can be attached to or included in a lid of a drink, and the data can include an indication that a particular number of reward units are to be added to a user account. Disruption of the electronic tag to retrieve a contained item. 
       FIGS. 2A and 2B  illustrates an example of an electronic tag  205  powered by an electronic device  225  and conditionally communicating data to the electronic device. 
     Electronic device  225  can routinely scan for nearby electronic tags. For example, electronic device  225  can convert electronic power (e.g., supplied via a battery) to electric and/or magnetic fields and repeatedly (e.g., at least 1, 5 or 20 times per second) transmit signals via an antenna (e.g., an RFID antenna) of the electronic device. A tag antenna  210  of electronic tag  205  can receive the signals, convert the electric and/or magnetic fields back to electronic power, and use the power to power an electronic chip  215  of tag antenna  210 . 
     Electronic chip  215  can use the power to, for example, retrieve data from a local memory, determine whether a transmission condition is satisfied and/or facilitate transmission (e.g., via tag antenna  210 ) of the retrieved data. Electronic chip  215  can include a microprocessor, memory and/or one or more capacitors (e.g., to tune antenna  210 ). 
     Data encoded and/or stored at electronic tag  205  can include, for example, data previously encoded by another (e.g., vendor) electronic user device. The encoded data can, in some instances, correspond to a purchase, product, food item and/or drink item. In one instance, encoded data includes a nutrition variable for a food item (e.g., to be provided with tag  205 ) and/or an alcohol variable for a drink item (e.g., to be provided with tag  205 ). In one instance, the data includes a nutrition or alcohol variable for a custom order (e.g., selectively including or reflecting nutrition information for items ordered by and/or being provided to a customer). Additional exemplary detail is provided in U.S. application No. 62/111,214 and 62/111,292, each filed on Feb. 3, 2015, each of which is hereby incorporated by reference in its entirety for all purposes. The data can include, for example, locked or unlocked data. The data can include variables that can be used by an app on electronic device  225  to track a user behavior (e.g., calorie intake) and/or estimate a user-related variable (e.g., blood alcohol concentration). 
     Antenna  210  can include, for example, a coil and/or loop antenna. Antenna  210  can include a plurality of loops, in some instances, at least two loops can differ in a radius or other dimension. This variation can allow the loops to be positioned in a plane, which can allow a thickness of electronic tag  205  to remain small. Nonetheless, in some instances, antenna  210  can instead include a plurality of loops having a similar or same radius (and/or some or all other dimensions) and/or being positioned in a stacked manner or a direction orthogonal to a primary surface of tag  205 . 
     In some instances, antenna  210  can be configured so as to be affected by a physical disruption (e.g., of a particular type) of tag  205 . For example, antenna  210  can include a segment configured to be severed by a separation of tag  205  into multiple pieces (e.g., tag pieces  205   a  and  205   b ). As illustrated in the depicted instance, antenna  210  can include an outer loop  210   a  having a shape and/or dimension corresponding to that of tag  205 . The dimension can be substantially larger (e.g., at least 5, 10, 50 or 100 times larger) than a corresponding dimension of one or all other loops in antenna  210 . Outer loop  210   a  can be positioned so as to be (e.g., in its entirety or at least in one location) within a defined distance (e.g., 1 cm, 5 mm, or 1 mm) from a perimeter of tag  205 . Outer loop  210   a  can be configured to be fragile (e.g., due to a material of outer loop  210   a  or a thickness the outer loop). In some instances, but not in others, outer loop  210   a  is of a different thickness or material as compared to one or all other loops in antenna  210 . For example, a thickness of a wire forming antenna  210  can be at least twice as thin in outer loop  210   a  relative to a most central loop. 
     The depicted positioning of outer loop  210   a  can cause the loop to be severed upon a tearing of tag  205 , as illustrated in  FIG. 2B . Tag  205  can be configured such that electronic chip  215  detects a disturbance of tag  205  by detecting a disturbance (e.g., severing) of outer loop  210   a . In one instance, outer loop  210   a  connects electronic chip  215  to a pin  220 . In some instances, electronic chip  215  and pin  220  can be positioned on opposite sides and/or corners of tag  205 . Antenna  210  and pin  220  can be configured (e.g., positioned and/or shaped) such that a severing of outer loop  210   a  prevents electronic chip  215  from detecting pin  220 . Electronic chip  215  can be configured so as to initiate transmission (e.g., via one or more undamaged loops in antenna  210  and/or another antenna) of data upon determining that pin  220  cannot be detected. 
     It will be appreciated that electronic tag  205  can, in some instances, include one or more additional components not shown in  FIGS. 2A and 2B . For example, electronic tag  205  can include a top and/or bottom layer or surface (e.g., such that chip  215  as depicted in  FIGS. 2A and 2B  is positioned between and/or enclosed within the surfaces), such as a laminate, plastic or paper surface. In some instances, a top surface includes text, a graphic and/or a code, and/or a bottom surface includes an adhesive. Text and/or a graphic on electronic tag  205  can correspond to an invitation to “tap” an electronic device to the tag or can indicate that positioning an electronic device near the tag will facilitate an information transfer from the tag to the device. 
     Electronic tag  205  can be flexible and/or can be attached to a flexible substrate. Electronic tag  205  can have a size that can be characterized according to multiple dimensions, such as length, width and thickness or radius and thickness. A thickness of electronic tag  205  can be less than, e.g., 10, 50 or 100 microns, or 1, 5 or 10 millimeters. A length, width and/or radius of electronic tag can be, for example, greater than 0.1, 0.5 or 1 centimeters and/or less than 1, 3, 5, 10, 30 or 50 centimeters. 
     In some instances, electronic tag  205  is part of or is attached to a seal. The seal can include an adhesive bottom layer (e.g., which may be adhesive across part or all of the bottom layer) and a non-adhesive top layer. Electronic tag  205  can be included as part of one or both of the layers, attached to one or one or both of the layers and/or positioned in between the layers. For example, electronic tag  205  can be secured on top of the top layer. In some instances, electronic tag  205  may be positioned within a middle (along an axis perpendicular to a top-bottom axis) of the two layers. The seal may be configured to be positioned at least partly on an opening of a container (e.g., a food container) so as to inhibit opening of the container. Such positioning may inhibit or prevent a user from opening the container along the opening with removing, bending and/or tearing the seal. For example, a container may include a sandwich box that, without the seal, pivots at a first end of the box such that the box opens and closes (by separating and contracting top and bottom portions of the box) at a second opposite end. The seal can be positioned at the second opposite end (e.g., at least partly on each of the top and bottom portions) so as to inhibit opening of the box. As another example, the seal can be positioned at least partly on a top portion of a bag and a side of the bag, such that the seal promotes keeping the bag in a folded, closed position. 
     It will also be appreciated that, in some instances, tag  205  can include a configuration different than that described in relation to  FIGS. 2A and/or 2B . For example, tag  205  can include an antenna  210  of a different shape and/or not including an outer loop  210   a  having a substantially different radius or other dimension relative to other loops in antenna  210 . Meanwhile, antenna  210  can include a sensor, such as a vibration sensor and/or an accelerometer, which can be able to detect movements indicative of tag  205  being torn. Particular measurements from the sensor (e.g., above-threshold measurements) can trigger transmission of data from tag  205 . 
     As another example, tag  205  need not include pin  220 . In some instances, tag  205  can nonetheless detect a breaking of outer loop  210   a  via other techniques. For example, chip  215  can detect a pattern of transmissions received from a nearby electronic device. An abrupt change in received transmissions can be indicative of a break in outer loop  210   a  or another disruption to antenna  210 . 
     As yet another example, in some instances, chip  215  need not be configured to detect a physical disturbance of tag  205  (e.g., via a failure to detect a pin, detecting an above-threshold sensor measurement or detecting a change in received communications). For example, chip  215  can initiate transmission whenever possible, so long as sufficient power is available and/or when one or more other conditions are satisfied. Electronic device  225  can then determine whether to store and/or use (e.g., via an app) data received from tag  205 . This determination can be based on, for example, determining whether a characteristic of a transmission from tag  205  abruptly changed (e.g., detecting that a change in a signal strength is below a negative threshold or that transmissions from tag  205  ceased without preceding corresponding reduced signal strength). 
     Electronic device  225  can include a user, portable and/or handheld device, such as a smartphone, portable music player, smart wearable device (e.g., watch, glasses, wristband or armband). In some instances, electronic device  225  is configured to be worn on an arm, wrist or hand of a user. Such configuration may promote short-range data transfers between electronic tags associated with items the user is using or investigating and electronic device  225 . Electronic device  225  and/or an app on electronic device  225  can be configured to present data received from electronic tag (e.g., via an app page or by displaying a webpage corresponding to a webpage link in the data) and/or to perform one or more actions in response to receipt of the data. For example, a calorie or reward count can be incremented, a nutritional recommendation can be made (e.g., identifying a target upper threshold of calories) or an estimated blood alcohol level can be updated. 
       FIG. 3  is an example schematic diagram of an electronic tag  300  (e.g., electronic tag  205 ) according to an embodiment of the present invention. Electronic tag  300  can include processing subsystem  302 , storage subsystem  304 , one or more connection components (e.g., transceiver subsystem  308 ), a power subsystem  312  and/or (in some embodiments) one or more sensors  314 . Electronic tag  300  can also include other components (not explicitly shown). 
     Storage subsystem  304  can be implemented, e.g., using magnetic storage media, flash memory, other semiconductor memory (e.g., DRAM, SRAM), or any other non-transitory storage medium, or a combination of media, and can include volatile and/or non-volatile media. In some instances, some or all of the memory in storage subsystem  304  is readable and writable. In some instances, storage subsystem  304  can be configured such that (e.g., after encoding of tag  300 ) part or all of the memory can be locked to prevent alteration. Memory in storage subsystem  304 , in some instances, can be less than or equal to 1 or 10 kB. 
     In some embodiments, storage subsystem  304  can store data.  332  to be (e.g., conditionally or unconditionally) transmitted to one or more nearby devices. Data  332  can include data encoded via another device and/or software (e.g., encoded via RFID and/or NFC). Data  332  can include, for example, text, a link (e.g., a web address) and/or a command. U.S. Application Nos. 62/111,214 and 62/111,292, each filed on Feb. 3, 2015, and each of which is hereby incorporated by reference in its entirety for all purposes, disclose exemplary electronic vendor devices, encoding processes and types of encoded data. Data  332  can be locked or unlocked. In some instances, one or more NFC Data Encoding Function (NDEF) payloads can be generated to include data  332  (e.g., within one or more records of a message of the NDEF message). The message can also include, for example, a header corresponding to each of the one or more payloads. 
     In some instances, tag  300  can be configured to accompany a product, such as a food product sold at an eatery or a piece of merchandise. For example, tag  300  can include or can be a sticker to be placed on a package or container of the product or can be part of a package or container. An electronic vendor device can then encode data that relates to the product and/or a purchase of the product. Such data  332  can include information about and/or related to the product (e.g., assembly and/or use instructions, warranty information, nutritional information, related products, user reviews of the product and/or a selling merchant, an option to provide a review of the product and/or a merchant, and/or a reward to be provided in response to the purchase). For example, an electronic vendor device can identify items to be included in a custom order and can encode the tag with data  332  that includes nutrition information particular to those items. For example, for an order of a hamburger, fries and drink, data  332  can include a per-item and/or total calorie count and/or other nutrition data (e.g., quantity of fat, sodium, protein and/or sugar). As another example, for an order of a hamburger with added mayonnaise and no ketchup, the vendor device can identify a calorie count and/or other nutrition data for the ordered hamburger in total and/or can identify nutrition data for the base hamburger, the added mayonnaise and the ketchup (to be excluded). 
     Data  332  can additionally or alternatively include a command to modify account data to reflect, for example, purchase and/or use of the product. To illustrate, the modification can include incrementing a product-purchase counter, incrementing a reward count by a defined number, incrementing nutritional values (e.g., calorie counts, fat-gram counts and/or vitamin-unit counts) by defined amounts, and/or adjusting an estimated blood alcohol level based on an identified quantity of alcohol. 
     Data  332  can additionally or alternatively include a command to initiate or facilitate presentation of a reminder. For example, tag  300  can include one to be provided with a medication, such that tearing of tag  300  can be estimated to be indicative of a person accessing and taking the medication. Data  332  can identify a number of doses having been provided, a scheduling regime of administration, an expected date of completion of the provided medication, a number of available refills, and/or other information (e.g., one or more potential side effects). In some instances, an electronic device can use data  332  to generate a reminder to obtain a refill of a prescription if needed and/or to determine when to (e.g., locally or remotely) present the reminder. For example, data  332  can be transmitted on November 1 that indicates that indicates that a prescription is a 2-week prescription and that a refill reminder is to be presented 3 days prior to an estimated completion date. An electronic device receiving data  332  can then identify a reminder date as being November 11 and can present the reminder on that date. 
     In some embodiments, storage subsystem  304  can also store one or more transmission conditions  334  that identify when some or all of data  332  is to be transmitted. For example, a transmission condition can identify a pin or a number of pins and be configured to trigger data transmission when the pin or number of pins are not detected. As another example, a transmission condition can identify a threshold for a sensor measurement and be configured to trigger data transmission when a detected measurement exceeds the threshold (e.g., in a positive direction or, alternatively, in a negative direction). As yet another example, a transmission condition can identify a characteristic of received transmissions. To illustrate, a condition can set forth a technique for identifying a frequency of communications being received from an electronic device and a trend in signal strengths of the communications. The condition can indicate that data transmission is to be triggered upon detecting that a power of a received communication departs from the identified trend (e.g., has decreased by more than a particular amount) or has not been received despite previously strong signal strengths. 
     In some instances, one or more transmission conditions identify which data is to be transmitted. For example, for a tag configured to accompany a food product, a detection of nearby device (e.g., via interception of electric and/or magnetic fields) can trigger tag  300  to transmit nutritional data to the device, and detection of physical disturbance of the tag can trigger tag  300  to transmit data including a command to adjust one or more nutritional counts (e.g., a calorie count) based on the nutritional data. 
     In some embodiments, a transmission condition can be configured to trigger or facilitate transmission of data  332  upon detecting satisfaction of a transmission condition defining a tag disturbance. Thus, storage subsystem  304  can also store code for a disturbance detector module  336 . The disturbance detector module can be configured to monitor, for example, incoming transmissions, sensor readings, and/or pin detections. In some instances, one or more variables can be generated based on the monitoring, such as an inter-communication time, transmission frequency, signal strength, change in signal strength, change in a sensor reading, number of pins detected or whether a particular pin was detected. In some instances, a threshold can be identified, and a detected or generated variable can be compared to the threshold. The threshold can include one set forth in a transmission condition or generated based on a technique or formula as set forth in a transmission condition (e.g., using recently detected values to define the threshold). 
     The disturbance detector module can determine that a physical disturbance has been detected, for example, when a particular detection is made (e.g., detection of a particular pin), a particular detection is not made (e.g., a particular pin is not detected), a detected or generated value (e.g., a sensor measurement or variable determined based on one or more sensor measurements, or a characteristic of one or more incoming communications) exceeds a threshold. 
     Processing subsystem  302  can be implemented as one or more integrated circuits, e.g., one or more single-core or multi-core microprocessors or microcontrollers, examples of which are known in the art. In operation, processing system  302  can control the operation of electronic tag  300 . In various embodiments, processing subsystem  304  can execute a variety of programs in response to program code and can maintain multiple concurrently executing programs or processes. At any given time, some or all of the program code to be executed can be resident in processing subsystem  304  and/or in storage media such as storage subsystem  304 . 
     Through suitable programming, processing subsystem  302  can provide various functionality for electronic tag  300 . For example, in some embodiments, processing subsystem  302  can execute code for disturbance detector module  336 , evaluation of transmission conditions  334  and/or code to facilitate transmission of data  332 . 
     Transceiver subsystem  308  can allow electronic tag  300  to communicate wirelessly with various electronic devices. Transceiver interface  308  can include a component, such as an antenna (e.g., a radio frequency identification (RFID) tag antenna  309 ) and supporting circuitry to enable data communication over a wireless medium, e.g., using near-field communication (NFC), Bluetooth Low Energy, Bluetooth® (a family of standards promulgated by Bluetooth SIG, Inc.), Zigbee, Wi-Fi (IEEE 802.11 family standards), or other protocols for wireless data communication. In some embodiments, transceiver subsystem  308  can implement a proximity sensor that supports proximity detection (e.g., via NFC or Bluetooth Low Energy) through a detection of a signal, estimation of signal strength and/or other protocols for determining proximity to another electronic apparatus. 
     RFID tag antenna  309  can include, for example, an NFC antenna and/or a loop antenna with one or more loops. In some instances, a length of antenna is less than, e.g., 1, 3, 5 or 10 cm. RFID tag antenna  309  can include or be a passive, receiving antenna. An operating frequency of RFID tag antenna  309  can include a low frequency (e.g., 125-134 kHz), high frequency (e.g., between 10-30 MHz, such as 13.56 MHz) or ultra-high frequency (e.g., greater than 800 MHz). 
     In some embodiments, transceiver subsystem  308  can provide NEC capability, e.g., implementing the ISO/IEC 18092 standards or the like; NFC can support wireless data exchange between devices over a very short range (e.g., 20 centimeters or less). Transceiver subsystem  308  can be implemented using a combination of hardware (e.g., driver circuits, antennas, modulators/demodulators, encoders/decoders, and other analog and/or digital signal processing circuits) and software components. Multiple different wireless communication protocols and associated hardware can be incorporated into transceiver subsystem  308 . In some instances, a same component of transceiver subsystem  308  can serve to receive incoming signals and transmit outgoing signals. In some instances, different components handle incoming and outgoing signals. 
     In some embodiments, electronic tag  300  includes a power subsystem  312  that can provide power management capabilities for electronic tag and, in some instances, can provide power for electronic tag  300 . Power subsystem  312  can include circuitry to distribute received, converted and/or stored power to other components of electronic tag  300  that require electrical power. 
     In some instances, power subsystem  312  can convert electric and/or magnetic fields (e.g., received via antenna  309 ) into electrical energy, which can be distributed to tag components and/or used to charge a local battery. In some (but not other instances), power subsystem  312  can include a battery  340  (e.g., a rechargeable battery) and can also include circuitry operable to charge battery  340 . Thus, in some embodiments, power subsystem  312  can include a “wireless” charger, such as an inductive charger, to charge battery  340 . This capability can be used to extend a time during which tag  300  can transmit data (e.g., such that data can be transmitted even when it is not sufficiently close to be powered by a nearby electronic device) and/or can allow electronic tag  300  to communicate using a different communication protocol and/or over a larger range. For example, power can be received via NFC from a nearby electronic device and used to charge battery  340 . As the device is moved away from the device, tag  300  may be unable to communicate with the device via NFC. However, the charge of the battery can allow tag  300  to use a more power-intensive protocol (e.g., Bluetooth Low Energy) to communicate with the device, thereby extending a time during which the tag and device can communicate. In some embodiments, power subsystem  312  can also include other power sources, such as a solar cell, in addition to or instead of battery  340 . 
     In some embodiments, power subsystem  312  can control power distribution to components within electronic tag  300  to manage power consumption efficiently. For example, power subsystem  312  can automatically place device  300  into a “hibernation” state when it is determined or inferred that no electronic device is nearby (e.g., due to a lack of incoming signals). The hibernation state can serve to inhibit or pause outgoing transmissions of data. 
     Power subsystem  312  can also provide other power management capabilities, such as regulating power consumption of other components of electronic tag  300  based on the source and amount of available power, monitoring stored power in battery  340 , and so on. 
     In some embodiments, control functions of power subsystem  312  can be implemented using programmable or controllable circuits operating in response to control signals generated by processing subsystem  302  in response to program code executing thereon, or as a separate microprocessor or microcontroller. 
     In some instances, electronic tag  300  includes one or more sensors  314 , such as one or more electronic, mechanical, electromechanical, optical, or other devices that provide information related to internal external conditions around electronic tag  300 . Sensors  314  in some embodiments can provide digital signals to processing subsystem  302 , e.g., on a streaming basis or in response to polling by processing subsystem  302  as desired. Any type and combination of sensors can be used; shown by way of example are a pin detector  343  and a vibration sensor  349 . Pin detector  343  can detect, for example, how many pins tag  300  detects (e.g., via a connection between individual pins and antenna  309 ), which pins are detected and/or which pins are detected (e.g., or which portions of tag  300  detect pins). This detection can be used to evaluate a transmission condition (e.g., such that transmission can be facilitated or initiated upon failure to detect a pin). 
     A vibration sensor  349  can be configured to detect a vibration of one or more parts of tag  300  or all of tag  300 . Vibration sensor  349  can include, for example, a piezoelectric material configured to convert mechanical strain into electrical energy. This detection can be used to evaluate a transmission condition (e.g., such that transmission can be facilitated or initiated upon detection of sensor readings exceeding a threshold). One or more other sensors (e.g., an accelerometer) can also be included in addition to or instead of these examples. 
     It will be appreciated that electronic tag  300  is illustrative and that variations and modifications are possible. For example, transceiver subsystem  308  can include a different type of antenna  309  and/or can include one or more frequency-tuning components (e.g., capacitors). 
     Further, while the electronic tag  300  is described with reference to particular blocks, it is to be understood that these blocks are defined for convenience of description and are not intended to imply a particular physical arrangement of component parts. Further, the blocks need not correspond to physically distinct components. Blocks can be configured to perform various operations, e.g., by programming a processor or providing appropriate control circuitry, and various blocks might or might not be reconfigurable depending on how the initial configuration is obtained. Embodiments of the present invention can be realized in a variety of apparatus including electronic tags implemented using any combination of circuitry and software. It is also not required that every block in  FIG. 3  be implemented in a given embodiment of an electronic tag. 
       FIG. 4  is an example schematic diagram of an electronic device  400  (e.g., electronic device  225 ) according to an embodiment of the present invention. Electronic device  400  can include processing subsystem  402 , storage subsystem  404 , user interface  406 , one or more connection components (e.g., RF subsystem  408  and/or connector interface  410 ), power subsystem  412 , and environmental sensors  414 . In some instances, one or more components of electronic device  400  can parallel or complement similarly numbered components of electronic tag  300 . Electronic device  400  can also include other components (not explicitly shown). 
     Storage subsystem  404  can be implemented, e.g., using magnetic storage media, flash memory, other semiconductor memory (e.g., DRAM, SRAM), or any other non-transitory storage medium, or a combination of media, and can include volatile and/or non-volatile media. In some embodiments, storage subsystem  404  can store media items such as audio files, video files, image or artwork files; information about a user&#39;s contacts (names, addresses, phone numbers, etc.); appointments and events; notes; and/or other types of information, examples of which are described below. 
     In some embodiments, storage subsystem  404  can also store code or instructions for an operating system  437  and/or one or more application programs (or apps)  438  to be executed by processing subsystem  402 . Apps  438  can include, for example, a tracking app, such as an app configured to track eating patterns, estimated alcohol levels, spending patterns and/or rewards. 
     Storage subsystem  404  can, in some instances, also include code or instructions for a data management module  439 , which can detect incoming data (e.g., included in one or more signals from an electronic tag) and control whether to store all or part of the data and/or distribute all or part of the data to one or more apps. Data management module  439  can make this determination by, for example, identifying and/or analyzing one or more characteristics of received signals. For example, data management module  439  can use one or more recent transmissions from an electronic tag to predict whether (e.g., and when) a next signal is expected and/or signal strength of a next transmission. Upon determining that an expected signal has not been received or that a signal strength is below an expected value (e.g., and a defined buffer), data management module  439  can store, route or avail data included in a current or previous communication. As another example, data management module  439  can determine a change in signal strength or latency between two signals from an electronic tag. Upon detecting a change value below a defined threshold, data management module  439  can store, route or avail data included in a current or previous communication. 
     In some instances, an app includes a data management module. For example, an app can determine whether to adjust a tracked parameter based on received data based on whether transmissions from an electronic tag abruptly stopped (e.g., without a preceding decrease in signal strength of a defined magnitude) and/or whether a decrease in signal strengths of the transmissions is below a defined threshold. 
     User interface  406  can include any combination of input and output devices. In some instances, a user can operate input devices of user interface  406  to invoke the functionality of electronic device  400  and can view, hear, and/or otherwise experience output from electronic device  400  via output devices of user interface  406 . Examples of output devices include display  420 , speakers  422 , and haptic output generator  424 . Examples of input devices include microphone  426 , touch sensor  428 , and camera  429 . 
     Display  420  can be implemented using compact display technologies, e.g., LCD (liquid crystal display), LED (light-emitting diode), OLED (organic light-emitting diode), or the like. In some embodiments, display  420  can incorporate a flexible display element or curved-glass display element, allowing electronic device  400  to conform to a desired shape. One or more speakers  422  can be provided using small-form-factor speaker technologies, including any technology capable of converting electronic signals into audible sound waves. In some embodiments, speakers  422  can be used to produce tones (e.g., beeping or ringing) and can but need not be capable of reproducing sounds such as speech or music with any particular degree of fidelity. Haptic output generator  424  can be, e.g., a device that converts electronic signals into vibrations; in some embodiments, the vibrations can be strong enough to be felt by a user wearing electronic device  400  but not so strong as to produce distinct sounds. 
     Touch sensor  428  can include, e.g., a capacitive sensor array with the ability to localize contacts to a particular point or region on the surface of the sensor and in some instances, the ability to distinguish multiple simultaneous contacts. In some embodiments, touch sensor  428  can be overlaid over display  420  to provide a touchscreen interface, and processing subsystem  404  can translate touch events (including taps and/or other gestures made with one or more contacts) into specific user inputs depending on what is currently displayed on display  420 . 
     Camera  429  can include, e.g., a compact digital camera that includes an image sensor such as a CMOS sensor and optical components (e.g. lenses) arranged to focus an image onto the image sensor, along with control logic operable to use the imaging components to capture and store still and/or video images. Images can be stored, e.g., in storage subsystem  404  and/or transmitted by electronic device  400  to other devices for storage. Depending on implementation, the optical components can provide fixed focal distance or variable focal distance; in the latter case, autofocus can be provided. In some embodiments, camera  429  can be disposed along an edge of a face member of a device, e.g., the top edge, and oriented to allow a user to capture images of nearby objects in the environment such as a bar code or QR code. In other embodiments, camera  429  can be disposed on the front surface of a device face member, e.g., to capture images of the user. Zero, one, or more cameras can be provided, depending on implementation. 
     Microphone  426  can include any device that converts sound waves into electronic signals. In some embodiments, microphone  426  can be sufficiently sensitive to provide a representation of specific words spoken by a user; in other embodiments, microphone  426  can be usable to provide indications of general ambient sound levels without necessarily providing a high-quality electronic representation of specific sounds. 
     In some embodiments, user interface  406  can provide output to and/or receive input from an auxiliary device such as a headset. For example, audio jack  430  can connect via an audio cable (e.g., a standard 2.5-mm or 3.5-mm audio cable) to an auxiliary device. Audio jack  430  can include input and/or output paths. Accordingly, audio jack  430  can provide audio to the auxiliary device and/or receive audio from the auxiliary device. In some embodiments, a wireless connection interface can be used to communicate with an auxiliary device. 
     Processing subsystem  402  can be implemented as one or more integrated circuits, e.g., one or more single-core or multi-core microprocessors or microcontrollers, examples of which are known in the art. In operation, processing system  402  can control the operation of electronic device  400 . In various embodiments, processing subsystem  404  can execute a variety of programs in response to program code and can maintain multiple concurrently executing programs or processes. At any given time, some or all of the program code to be executed can be resident in processing subsystem  404  and/or in storage media such as storage subsystem  404 . 
     Through suitable programming, processing subsystem  402  can provide various functionality for electronic device  400 . For example, in some embodiments, processing subsystem  402  can execute an operating system (OS)  437 , one or more apps  438  and/or data management module  439 . 
     RF subsystem  408  can allow electronic device  400  to communicate wirelessly with various devices (e.g., an electronic tag). RF subsystem  408  can include RF transceiver components, such as an antenna (e.g., RFID reader antenna  409 ) and supporting circuitry to enable data communication over a wireless medium, e.g., using near-field communication (NFC), Bluetooth Low Energy, Bluetooth® (a family of standards promulgated by Bluetooth SIG, Inc.), Zigbee, Wi-Fi (IEEE 802.11 family standards), or other protocols for wireless data communication. In some embodiments, transceiver subsystem  308  can implement a proximity sensor that supports proximity detection (e.g., via NFC or Bluetooth Low Energy) through a detection of a signal, estimation of signal strength and/or other protocols for determining proximity to another electronic device. 
     RFID reader antenna  409  can include one or more antennas configured to transmit electric and/or magnetic signals (e.g., having linear or circular polarization). RFID reader antenna  409  can repeatedly scan for electronic tags. Because some tags can be passive and not including a power source (or can have a limited power reserve), to detect the tag, RFID reader antenna can repeatedly transmit a power signal. If such signal is transmitted while near a tag, the tag can convert the signal into electrical energy and use the energy to generate and transmit a signal back to electronic device  400 . In some instances, between 1 and 20 scanning transmissions can be transmitted per second. 
     In some embodiments, RF subsystem  408  can provide NFC capability, e.g., implementing the ISO/IEC 18092 standards or the like; NFC can support wireless data exchange between devices over a very short range (e.g., 20 centimeters or less). RF subsystem  408  can be implemented using a combination of hardware (e.g., driver circuits, antennas, modulators/demodulators, encoders/decoders, and other analog and/or digital signal processing circuits) and software components. Multiple different wireless communication protocols and associated hardware can be incorporated into RF subsystem  408 . In some instances, a same component of RF subsystem  408  can serve to receive incoming signals and transmit outgoing signals (e.g., by outputting a field and intercepting a modulation of the field). In some instances, different components handle incoming and outgoing signals. 
     Environmental sensors  414  can include various electronic, mechanical, electromechanical, optical, or other devices that provide information related to external conditions around electronic device  400 . Sensors  414  in some embodiments can provide digital signals to processing subsystem  402 , e.g., on a streaming basis or in response to polling by processing subsystem  402  as desired. Any type and combination of environmental sensors can be used; shown by way of example are an accelerometer  442  and GPS receiver  448 . 
     Some environmental sensors can provide information about the location and/or motion of electronic device  400 . For example, an accelerometer  442  can detect an acceleration of device  400  (e.g., generally or in each of one or more directions). As another example, a GPS receiver  448  can receive communications from multiple GPS satellites and estimate a location of device  400 . It will be appreciated that other sensors can also be included in addition to or instead of these examples. 
     Power subsystem  412  can provide power and power management capabilities for electronic device  400 . For example, power subsystem  412  can include a battery  440  (e.g., a rechargeable battery) and associated circuitry to distribute power from battery  440  to other components of electronic device  400  that require electrical power. In some embodiments, power subsystem  412  can also include circuitry operable to charge battery  440 , e.g., when connector interface  410  is connected to a power source. In some embodiments, power subsystem  412  can include a “wireless” charger, such as an inductive charger, to charge battery  440  without relying on connector interface  410 . In some embodiments, power subsystem  412  can also include other power sources, such as a solar cell, in addition to or instead of battery  440 . 
     Power subsystem  412  can also provide power management capabilities, such as regulating power consumption of other components of electronic device  400  based on the source and amount of available power, monitoring stored power in battery  440 , generating user alerts if the stored power drops below a minimum level, and so on. Power subsystem  412  can also coordinate distribution of power to RF subsystem  408  so as to facilitate conversion of electrical power to electric and/or magnetic fields to be transmitted in scanning signals and/or to electronic tags. 
     In some embodiments, control functions of power subsystem  412  can be implemented using programmable or controllable circuits operating in response to control signals generated by processing subsystem  402  in response to program code executing thereon, or as a separate microprocessor or microcontroller. In some embodiments, control functions of power subsystem  412  can be based on user interaction with the device (e.g., to power down components if a device has not been interacted with in a particular manner, such as via a touch, button press or network activity, for a defined period of time). 
     It will be appreciated that electronic device  400  is illustrative and that variations and modifications are possible. For example, device  400  can include an additional environmental sensor, such as a gyroscope to detect a position of electronic device  400 . 
     Further, while the electronic device is described with reference to particular blocks, it is to be understood that these blocks are defined for convenience of description and are not intended to imply a particular physical arrangement of component parts. Further, the blocks need not correspond to physically distinct components. Blocks can be configured to perform various operations, e.g., by programming a processor or providing appropriate control circuitry, and various blocks might or might not be reconfigurable depending on how the initial configuration is obtained. Embodiments of the present invention can be realized in a variety of apparatus including electronic devices implemented using any combination of circuitry and software. It is also not required that every block in  FIG. 4  be implemented in a given embodiment of an electronic device. 
       FIG. 5  is a flow diagram of a process  500  for conditioned transmission of data from an electronic tag to an electronic device according to an embodiment of the present invention. In some instances, execution of one or more apps on an electronic tag or electronic device can cause one or more processors of the electronic tag or electronic device to perform one or more actions in process  500 . In some instances, one or more modules (e.g., disturbance detector module  336  or data management module  439 ) can perform one or more actions in process  500 . 
     At block  505 , the electronic device can convert electrical current into electric and/or magnetic fields. For example, an oscillating electric current can be provided to an antenna (e.g., an RFID reader antenna) such that magnetic and/or electric fields are produced around antenna elements. In some instances, process  500  utilizes NFC, and block  505  produces a magnetic field. In some instances, an electromagnetic field is generated. 
     At block  510   a , the electronic device can transmit (e.g., radiate) the electric and/or magnetic fields (e.g., via an antenna). At block  510   b , the electronic tag can receive (e.g., intercept) the electrical and/or magnetic fields (e.g., via an antenna, such as an RFID tag antenna). 
     At block  515 , the electronic tag can convert the electric and/or magnetic fields back into electrical current. For example, the waves can exert force on electronics in antenna elements to produce oscillating currents. 
     In some instances, the electronic tag can be an active tag that includes a battery. At least part of the electrical current can then be used to partly or fully charge the battery. In some instances, the electronic tag can be a passive tag without a battery, and block  520  can be omitted from process  500 . 
     The electrical current can be used to perform one or more other actions (e.g., via direct use of the current or via a battery having been charged by the current), such as one or more of those in blocks  525 - 535   a . One action can include, at block  525 , detecting a physical disturbance of the tag. It will be appreciated that a detection of the physical disturbance can include, for example, detecting an above-threshold sensor measurement, absence of a pin detection or change in incoming transmissions that is indicative of the physical disturbance. Thus, the detection need not include actually detecting the physical disturbance itself but can instead detect another indication that the physical disturbance has occurred. 
     In some instances, the physical disturbance can be detected by collecting and assessing one or more sensor measurements. For example, one or more measurements from an accelerometer or vibration sensor can be collected. In some instances, the measurement(s) can be processed, e.g., to average the measurements across a time period. A sensor measurement (or processed version of one or more measurements) can be compared to a threshold, which can include (for example) a fixed threshold or a relative threshold (e.g., 150% of an average sensor reading across a previous 10-minute period). Detecting the physical disturbance can include determining that a sensor measurement or processed version of one or more measurements exceeds the threshold. 
     In some instances, the physical disturbance can be detected by monitoring pin detections. A physical disturbance can be detected by, for example, determining whether a particular portion of the tag (e.g., a particular portion of an antenna of the tag) is in contact with or detects a pin, whether a defined number (or at least a defined number) of pins are detected, whether a particular pin is detected. For example, an antenna can be configured such that a loop of the antenna is connected to a pin. If the loop is broken via a physical disturbance, a chip in the tag can fail to detect the pin. Thus, detecting whether a physical disturbance occurred can include determining that a pin is not detected. 
     In some instances, detecting a physical disturbance can include detecting that a characteristic (e.g., impedance or resistance) of an antenna of the tag has changed or exceeded a threshold. In some instances, detecting a physical disturbance can include detecting a change (e.g., an above-threshold change) in incoming signals. For example, an antenna can be configured to be fragile (e.g., via selection of a small width of the antenna and/or a weak material) at least partly track a perimeter of the tag and be within a defined small distance from an edge of the tag. Thus, a rip of the tag can break the antenna. Breaking the antenna can reduce the power that can be received from fields from an electronic device and/or can inhibit the tag from receiving a signal from the device. 
     Thus, detecting the physical disturbance can include, for example, detecting that a power received from an electronic device has dropped below an absolute threshold or relative threshold (e.g., 70% of the power provided in a previous 1-second interval). As another example, detecting the physical disturbance can include determining that a previous signal from an electronic device provided a power above a threshold and that no subsequent signal (at an expected time or within a defined time period) had been received. 
     In some instances, the electronic tag includes a perforation and can be configured to detect a physical disturbance that corresponds to separation of the tag at the perforation. For example, a chip and part of an antenna can be positioned on one side of the perforation, another part of the antenna can positioned on another side of the perforation, and the detection can correspond to detecting a break in the antenna. 
     At block  530 , the electronic tag can retrieve stored data, which can include data locally stored in a memory of the electronic tag. In some instances, the data can be retrieved in response to the detection at block  525 . The data can include locked data or unlocked data. The data can, for example, include text, a graphic, a webpage address and/or a command. For example, the data can include a command to generate and/or present a presentation reflecting information in the data. As another example, the data can include a command to increment a count (e.g., a reward, calorie, carbohydrate or expenditure count) by a specified number. 
     The data can relate to an item accompanying the electronic tag. For example, the electronic tag can be configured to be positioned on (e.g., stuck to), included in and/or connected to packaging of a product. The packaging can include, for example, a container, box, plastic cover, cup, or lid. The packaging can at least partly or fully enclose a product, such as a piece of merchandise, a toy, a food product, a drink or medication. The data can include instructions pertaining to the (e.g., enclosed) item, such as assembly instructions, use instructions, maintenance instructions and/or administration instructions. The data can include other information pertaining to the item, such as a name of the item, one or more features of the item, one or more specifications of the item, a warranty, nutritional information, alcohol content or one or more user reviews. The data can also include an identification of an app to which to avail part or all of the data. 
     The data can include a command, such as one indicating that a presentation is to be presented, such as one or more instructions, nutrition variables, item identifications or other data are to be presented on a receiving electronic device (e.g., immediately, at a particular time or upon receipt of a particular user input). A command can alternatively or additionally indicate that a variable (e.g., associated with a user account, such as a reward variable or cumulative nutrition variable) is to be updated based on the data. 
     At block  535   a , a tag signal can be transmitted that includes the retrieved data, and at block  535   b , the tag signal can be received at the electronic device. Block  535   a  can include, for example, modulating an existing field provided by the electronic device (e.g., that provided at block  510   a ) or by generating a new field corresponding to the data. In the latter instance, the electronic device can alternate between supplying and receiving electric and/or magnetic fields. The communication of blocks  535   a - b  can occur, for example, via NFC, a short-range network, using Bluetooth Low Energy, using Bluetooth, wirelessly and/or using a same communication protocol as used in blocks  510   a - b . Thus, at a time of transmission, the electronic device and electronic tag may be physically proximate (e.g., close enough for the transmission to occur via NFC, within 12 inches or within 6 inches). 
     At block  550 , the electronic device can store and/or use the data and/or avail the data to an app. For example, the data can include an identifier of an app. The electronic device can then initiate execution of the app if it is not currently executing and route data from the signal to be used by the app. The app can then, for example, use the data to adjust account data, change a tracked parameter (e.g., calories consumed), facilitate an informational presentation, facilitate transmission of some or all of the data to a remote server, generate a behavioral recommendation to be presented via a user interface and so on. As another example, the electronic device can use the data to perform a command as identified in the data. 
     It will be appreciated that process  500  is illustrative, and various alternative embodiments are contemplated. For example, alternative embodiments can include one or more additional actions, fewer actions and/or different actions relative to those depicted in  FIG. 5 . In one instances, blocks  505 - 520  can be omitted from process  500 . 
       FIG. 6  is a flow diagram of a process  600  for conditioning storage or use of data transmitted from an electronic tag to an electronic device based on detection of a tag signal change according to an embodiment of the present invention. Various blocks (e.g.,  605 ,  610   a - b ,  615 ,  620 ,  630 ,  635   a - b  and  640 ) in process  600  can parallel blocks with corresponding numbers in process  500 . However, in process  600 , the electronic tag need not detect a physical disturbance of the tag. In some instances, execution of one or more apps on an electronic tag or electronic device can cause one or more processors of the electronic tag or electronic device to perform one or more actions in process  600 . In some instances, one or more modules (e.g., disturbance detector module  336  or data management module  439 ) can perform one or more actions in process  600 . 
     Rather, the electronic device can detect the disturbance of the tag at block  637 . Block  637  can include identifying and/or assessing a characteristic of one or more tag signals received from the electronic tag. The characteristic can include, for example, a signal strength (e.g., strength of modulation of a field). Detection of a physical disturbance can correspond to detecting that the characteristic, a change in the characteristic across time or signals and/or an acceleration in the characteristic across time or signals is below a threshold. In response to the detection, the data represented in the tag signal can be stored, used and/or availed to an app, as further discussed herein. 
     Thus, embodiments of the present invention can provide a variety of techniques for detecting a physical disturbance of a tag and conditioning one or more actions (e.g., retrieval of stored data at the tag, transmission of data from the tag to an electronic device, storing the data at an electronic device, using (e.g., presenting) the data at an electronic device and/or availing the data to an app at an electronic device) on the detection. This conditioning can conserve resources of the tag and/or device and/or can restrict usage of data to appropriate instances. For example, a tag can store data including instructions to increment a reward count. However, such modification can be selectively appropriate in instances where an accompanying product was purchased. The physical disturbance can correspond to gaining access to an enclosed package and can indicate that the purchase was made and reward count increment is appropriate. Similarly, ripping a tag positioned on a fast food container can indicate that a nearby user is going to eat a food item in the container. Thus, it can be appropriate to adjust a nutritional tracker based on stored data identifying nutrition information of the food item. 
     Embodiments of the present invention, e.g., in methods, apparatus, computer readable media and the like, can be realized using any combination of dedicated components and/or programmable processors and/or other programmable devices. The various processes described herein can be implemented on the same processor or different processors in any combination. Where components are described as being configured to perform certain operations, such configuration can be accomplished, e.g., by designing electronic circuits to perform the operation, by programming programmable electronic circuits (such as microprocessors) to perform the operation, or any combination thereof. Further, while the embodiments described above may make reference to specific hardware and software components, those skilled in the art will appreciate that different combinations of hardware and/or software components may also be used and that particular operations described as being implemented in hardware might also be implemented in software or vice versa. 
     Computer programs incorporating various features of the present invention may be encoded and stored on various computer readable storage media; suitable media include magnetic disk or tape, optical storage media such as compact disk (CD) or DVD (digital versatile disk), flash memory, and other non-transitory media. Computer readable media encoded with the program code may be packaged with a compatible electronic device, or the program code may be provided separately from electronic devices (e.g., via Internet download or as a separately packaged computer-readable storage medium). 
     Thus, although the invention has been described with respect to specific embodiments, it will be appreciated that the invention is intended to cover all modifications and equivalents within the scope of the following claims.
